Color (or colour) photography is photography that uses media capable of reproducing colors. By contrast, black-and-white (monochrome) photography records only a single channel of luminance (brightness) and uses media capable only of showing shades of gray.
In color photography, electronic sensors or light-sensitive chemicals record color information at the time of exposure. This is usually done by analyzing the spectrum of colors into three channels of information, one dominated by red, another by green and the third by blue, in imitation of the way the normal human eye senses color. The recorded information is then used to reproduce the original colors by mixing various proportions of red, green and blue light (RGB color, used by video displays, digital projectors and some historical photographic processes), or by using dyes or pigments to remove various proportions of the red, green and blue which are present in white light (CMY color, used for prints on paper and transparencies on film).
Monochrome images which have been "colorized" by tinting selected areas by hand or mechanically or with the aid of a computer are "colored photographs", not "color photographs". Their colors are not dependent on the actual colors of the objects photographed and may be inaccurate.
The foundation of virtually all practical color processes, the three-color method was first suggested in an 1855 paper by Scottish physicist James Clerk Maxwell, with the first color photograph produced by Thomas Sutton for a Maxwell lecture in 1861. Color photography has been the dominant form of photography since the 1970s, with monochrome photography mostly relegated to niche markets such as art photography.
Colour photography was attempted beginning in the 1840s. Early experiments were directed at finding a "chameleon substance" which would assume the colour of the light falling on it. Some encouraging early results, typically obtained by projecting a solar spectrum directly onto the sensitive surface, seemed to promise eventual success, but the comparatively dim image formed in a camera required exposures lasting for hours or even days. The quality and range of the colour was sometimes severely limited mainly to primary colours, as in the chemically complicated "Hillotype" process invented by American daguerreotypist Levi Hill around 1850. Other experimenters, such as Edmond Becquerel, achieved better results but could find no way to prevent the colours from quickly fading when the images were exposed to light for viewing. Over the following several decades, renewed experiments along these lines periodically raised hopes and then dashed them, yielding nothing of practical value.
In 1886 Lippmann's interest had turned to a method of fixing the colors of the solar spectrum on a photographic plate. On 2 February 1891, he announced to the Academy of Sciences: "I have succeeded in obtaining the image of the spectrum with its colors on a photographic plate whereby the image remains fixed and can remain in daylight without deterioration." By April 1892, he was able to report that he had succeeded in producing color images of a stained glass window, a group of flags, a bowl of oranges topped by a red poppy and a multicolored parrot. He presented his theory of color photography using the interference method in two papers to the academy, one in 1894, the other in 1906.
The three-color method, which is the foundation of virtually all practical color processes whether chemical or electronic, was first suggested in an 1855 paper on color vision by Scottish physicist James Clerk Maxwell.
It is based on the Young-Helmholtz theory that the normal human eye sees color because its inner surface is covered with millions of intermingled cone cells of three types: in theory, one type is most sensitive to the end of the spectrum we call "red", another is more sensitive to the middle or "green" region, and a third which is most strongly stimulated by "blue". The named colors are somewhat arbitrary divisions imposed on the continuous spectrum of visible light, and the theory is not an entirely accurate description of cone sensitivity. But the simple description of these three colors coincides enough with the sensations experienced by the eye that when these three colors are used the three cones types are adequately and unequally stimulated to form the illusion of various intermediate wavelengths of light.
In his studies of color vision, Maxwell showed, by using a rotating disk with which he could alter the proportions, that any visible hue or gray tone could be made by mixing only three pure colors of light – red, green and blue – in proportions that would stimulate the three types of cells to the same degrees under particular lighting conditions. To emphasize that each type of cell by itself did not actually see color but was simply more or less stimulated, he drew an analogy to black-and-white photography: if three colorless photographs of the same scene were taken through red, green and blue filters, and transparencies ("slides") made from them were projected through the same filters and superimposed on a screen, the result would be an image reproducing not only red, green and blue, but all of the colors in the original scene.
The first color photograph made according to Maxwell's prescription, a set of three monochrome "color separations", was taken by Thomas Sutton in 1861 for use in illustrating a lecture on color by Maxwell, where it was shown in color by the triple projection method. The test subject was a bow made of ribbon with stripes of various colors, apparently including red and green. During the lecture, which was about physics and physiology, not photography, Maxwell commented on the inadequacy of the results and the need for a photographic material more sensitive to red and green light. A century later, historians were mystified by the reproduction of any red at all, because the photographic process used by Sutton was for all practical purposes totally insensitive to red light and only marginally sensitive to green. In 1961, researchers found that many red dyes also reflect ultraviolet light, coincidentally transmitted by Sutton's red filter, and surmised that the three images were probably due to ultra-violet, blue-green and blue wavelengths, rather than to red, green and blue.
Creating colors by mixing colored lights (usually red, green and blue) in various proportions is the additive method of color reproduction. LCD, LED, plasma and CRT (picture tube) color video displays all use this method. If one of these displays is examined with a sufficiently strong magnifier, it will be seen that each pixel is actually composed of red, green and blue sub-pixels which blend at normal viewing distances, reproducing a wide range of colors as well as white and shades of gray. This is also known as the RGB color model.
The same three images taken through red, green and blue filters which are used for additive color synthesis may also be used to produce color prints and transparencies by the subtractive method, in which colors are subtracted from white light by dyes or pigments. In photography, the dye colors are normally cyan, a greenish-blue which absorbs red; magenta, a purplish-pink which absorbs green; and yellow, which absorbs blue. The red-filtered image is used to create a cyan dye image, the green-filtered image to create a magenta dye image, and the blue-filtered image to create a yellow dye image. When the three dye images are superimposed they form a complete color image.
This is also known as the CMYK color model. The "K" is a black component normally added in ink-jet and other mechanical printing processes to compensate for the imperfections of the colored inks used, which ideally should absorb or transmit various parts of the spectrum but not reflect any color, and to improve image definition.
At first it may seem that each image ought to be printed in the color of the filter used in making it, but by following any given color through the process the reason for printing in complementary colors should become apparent. A red object, for example, will be very pale in the red-filtered image but very dark in the other two images, so the result will be an area with just a trace of cyan, absorbing just a bit of red light, but a large amount of magenta and yellow, which together absorb most of the green and blue light, leaving mainly red light to be reflected back from the white paper in the case of a print, or transmitted through a clear support in the case of a transparency.
Before the technical innovations of the years 1935 to 1942, the only way to create a subtractive full-color print or transparency was by means of one of several labor-intensive and time-consuming procedures. Most commonly, three pigment images were first created separately by the so-called carbon process and then carefully combined in register. Sometimes, related processes were used to make three gelatin matrices which were dyed and assembled or used to transfer the three dye images into a single layer of gelatin coated on a final support. Chemical toning could be used to convert three black-and-white silver images into cyan, magenta and yellow images which were then assembled. In a few processes, the three images were created one on top of another by repeated coating or re-sensitizing, negative registration, exposure and development operations. A number of variations were devised and marketed during the first half of the 20th century, some of them short-lived, others, such as the Trichrome Carbro process, enduring for several decades. Because some of these processes allow very stable and light-fast coloring matter to be used, yielding images which can remain virtually unchanged for centuries, they are still not quite completely extinct.
The production of photographic three-color prints on paper was pioneered by Louis Ducos du Hauron, whose comprehensive 1868 French patent also included the basic concepts of most of the color photographic processes which were subsequently developed. For making the three color-filtered negatives required, he was able to develop materials and methods which were not as completely blind to red and green light as those used by Thomas Sutton in 1861, but they were still very insensitive to those colors. Exposure times were impractically long, the red or orange-filtered negative requiring hours of exposure in the camera. His earliest surviving color prints are "sun prints" of pressed flowers and leaves, each of the three negatives having been made without a camera by exposing the light-sensitive surface to direct sunlight passing first through a color filter and then through the vegetation. His first attempts were based on the red-yellow-blue colors then used for pigments, with no color reversal. Later he used the primary colors of light with color reversal.
As long as photographic materials were usefully sensitive only to blue-green, blue, violet and ultraviolet, three-color photography could never be practical. In 1873 German chemist Hermann Wilhelm Vogel discovered that the addition of small amounts of certain aniline dyes to a photographic emulsion could add sensitivity to colors which the dyes absorbed. He identified dyes which variously sensitized for all the previously ineffective colors except true red, to which only a marginal trace of sensitivity could be added. In the following year, Edmond Becquerel discovered that chlorophyll was a good sensitizer for red. Although it would be many more years before these sensitizers (and better ones developed later) found much use beyond scientific applications such as spectrography, they were quickly and eagerly adopted by Louis Ducos du Hauron, Charles Cros and other color photography pioneers. Exposure times for the "problem" colors could now be reduced from hours to minutes. As ever-more-sensitive gelatin emulsions replaced the old wet and dry collodion processes, the minutes became seconds. New sensitizing dyes introduced early in the 20th century eventually made so-called "instantaneous" color exposures possible.
Making color separations by reloading the camera and changing the filter between exposures was inconvenient, added delays to the already long exposure times and could result in the camera being accidentally shifted out of position. To improve the actual picture-taking, a number of experimenters designed one or more special cameras for color photography. They were usually of two main types.
The first type used a system of partially reflecting surfaces to divide the light coming through the lens into three parts, each part passing through a different color filter and forming a separate image, so that the three images could be photographed at the same time on three plates (flexible film had not yet replaced glass plates as the support for the emulsion) or different areas of one plate. Later known as "one-shot" cameras, refined versions continued to be used as late as the 1950s for special purposes such as commercial photography for publication, in which a set of color separations was ultimately required in order to prepare printing plates.
The second type, known variously as a multiple back, repeating back or drop back camera, still exposed the images one at a time but used a sliding holder for the filters and plates which allowed each filter and the corresponding unexposed area of emulsion to be quickly shifted into place. German photochemistry professor Adolf Miethe designed a high-quality camera of this type which was commercially introduced by Bermpohl in 1903. It was probably this Miethe-Bermpohl camera which was used by Miethe's pupil Sergei Mikhailovich Prokudin-Gorskii to make his now-celebrated color photographic surveys of Russia before the 1917 revolution. One sophisticated variant, patented by Frederic Eugene Ives in 1897, was driven by clockwork and could be adjusted to automatically make each of the exposures for a different length of time according to the particular color sensitivities of the emulsion being used.
Otherwise simple cameras with multiple color-filtered lenses were sometimes tried, but unless everything in the scene was at a great distance, or all in a plane at the same distance, the difference in the viewpoints of the lenses (parallax) made it impossible to completely "register" all parts of the resulting images at the same time.
Prior to the late 1890s color photography was strictly the domain of a very few intrepid experimenters willing to build their own equipment, do their own color-sensitizing of photographic emulsions, make and test their own color filters and otherwise devote a large amount of time and effort to their pursuits. There were many opportunities for something to go wrong during the series of operations required and problem-free results were rare. Most photographers still regarded the whole idea of color photography as a pipe dream, something only madmen and swindlers would claim to have accomplished.
In 1898, however, it was possible to buy the required equipment and supplies ready-made. Two adequately red-sensitive photographic plates were already on the market, and two very different systems of color photography with which to use them, tantalizingly described in photographic magazines for several years past, were finally available to the public.
The most extensive and expensive of the two was the "Kromskop" (pronounced "chrome-scope") system developed by Frederic Eugene Ives. This was a straightforward additive system and its essential elements had been described by James Clerk Maxwell, Louis Ducos du Hauron and Charles Cros much earlier, but Ives invested years of careful work and ingenuity in refining the methods and materials to optimize color quality, in overcoming problems inherent in the optical systems involved, and in simplifying the apparatus to bring down the cost of producing it commercially. The color images, dubbed "Kromograms", were in the form of sets of three black-and-white transparencies on glass, mounted onto special cloth-tape-hinged triple cardboard frames. To see a Kromogram in color it had to be inserted into a "Kromskop" (generic name "chromoscope" or "photochromoscope"), a viewing device which used an arrangement of colored glass filters to illuminate each slide with the correct color of light and transparent reflectors to visually combine them into a single full-color image. The most popular model was stereoscopic. By looking through its pair of lenses, an image in full natural color and 3-D was seen, a startling novelty in the late Victorian age.
The results won near-universal praise for excellence and realism. At demonstrations, Ives sometimes placed a viewer displaying a still-life subject next to the actual objects photographed, inviting direct comparison. A Kromskop triple "lantern" could be used to project the three images, mounted in a special metal or wooden frame for this purpose, through filters as Maxwell had done in 1861. Prepared Kromograms of still-life subjects, landscapes, famous buildings and works of art were sold and these were the Kromskop viewer's usual fodder, but a "multiple back" camera attachment and a set of three specially adjusted color filters could be bought by "Kromskopists" wishing to make their own Kromograms.
Kromskops and ready-made Kromograms were bought by educational institutions for their value in teaching about color and color vision, and by individuals who were in a position to pay a substantial sum for an intriguing optical toy. A few people did, indeed, make their own Kromograms. Unfortunately for Ives, this was not enough to sustain the businesses which had been set up to exploit the system and they soon failed, but the viewers, projectors, Kromograms and several varieties of Kromskop cameras and camera attachments continued to be available through the Scientific Shop in Chicago as late as 1907.
The simpler and somewhat more economical alternative was the Joly Screen process. This required no special camera or viewer, just a special color-compensating filter for the camera lens and a special holder for the photographic plates. The holder contained the heart of the system: a clear glass plate on which very fine lines of three colors had been ruled in a regular repeating pattern, completely covering its surface. The idea was that instead of taking three separate complete photographs through three colored filters, the filters could be in the form of a large number of very narrow strips (the colored lines) allowing the necessary color information to be recorded in a single compound image. After the negative was developed, a positive transparency was printed from it and a viewing screen with red, green and blue lines in the same pattern as the lines of the taking screen was applied and carefully aligned. The colors then appeared as if by magic. The transparency and screen were very like the layer of monochrome liquid crystal elements and overlay of hair-thin red, green and blue color filter stripes which create the color image in a typical LCD display. This was the invention of Irish scientist John Joly, although he, like so many other inventors, eventually discovered that his basic concept had been anticipated in Louis Ducos du Hauron's long-since-expired 1868 patent.
The Joly Screen process had some problems. First and foremost, although the colored lines were reasonably fine (about 75 sets of three colored lines to the inch) they were still disturbingly visible at normal viewing distances and nearly intolerable when enlarged by projection. This problem was exacerbated by the fact that each screen was individually ruled on a machine which used three pens to apply the transparent colored inks, resulting in irregularities, high reject rates and high cost. The glass used for photographic plates at the time was not perfectly flat, and lack of uniform good contact between the screen and the image gave rise to areas of degraded color. Poor contact also caused false colors to appear if the sandwich was viewed at an angle. Although much simpler than the Kromskop system, the Joly system was not inexpensive. The starter kit of plate holder, compensating filter, one taking screen and one viewing screen cost US$30 (the equivalent of at least $750 in 2010 dollars) and additional viewing screens were $1 each (the equivalent of at least $25 in 2010 dollars). This system, too, soon died of neglect, although in fact it pointed the way to the future.
Surviving examples of the Joly process usually show extremely poor color now. The colors in the viewing screens have badly faded and shifted, making it impossible to judge their original appearance. In some specimens the viewing screen is also misaligned.
Lippmann photography is a way of making a color photograph that relies on Bragg reflection planes in the emulsion to make the colors. It is similar to using the colors of soap bubbles to make an image. Gabriel Jonas Lippmann won the Nobel Prize in physics in 1908 for the creation of the first color photographic process using a single emulsion. The color fidelity is extremely high but the images can not be reproduced and viewing requires very specific lighting conditions. The development of the Autochrome process quickly rendered the Lippmann method redundant. The method is still utilized to make singular images that cannot be copied for security purposes.
The first commercially successful color process, the Lumière Autochrome, invented by the French Lumière brothers, reached the market in 1907. Instead of colored strips, it was based on an irregular screen plate filter made of three colors of dyed grains of potato starch which were too small to be individually visible. The light-sensitive emulsion was coated directly onto the screen plate, eliminating problems due to imperfect contact between the screen and image. Reversal processing was used to convert the negative image which was initially produced into a positive image by removing the exposed silver metal, and re-exposing the remaining silver halide, so no printing or screen registration was required. The shortcomings of the Autochrome process were the expense (one plate cost about as much as a dozen black-and-white plates of the same size), the relatively long exposure times which made hand-held "snapshots" and photographs of moving subjects impractical, and the density of the finished image due to the presence of the light-absorbing color screen.
Viewed under optimum conditions and by daylight as intended, a well-made and well-preserved Autochrome can look startlingly fresh and vivid. Unfortunately, modern film and digital copies are usually made with a highly diffused light source, which causes loss of color saturation and other ill effects due to light scatter within the structure of the screen and emulsion, and by fluorescent or other artificial light which alters the color balance. The capabilities of the process should not be judged by the dull, washed-out, odd-colored reproductions commonly seen.
Millions of Autochrome plates were manufactured and used during the quarter century before the plates were replaced by film-based versions in the 1930s. The very last film version, named Alticolor, brought the Autochrome process into the 1950s but was discontinued in 1955. Many additive color screen products were available between the 1890s and the 1950s, but none, with the possible exception of Dufaycolor, introduced as film for still photography in 1935, was as popular or successful as the Lumière Autochrome. The most recent use of the additive screen process for non-digital photography was in Polachrome, an "instant" 35mm slide film introduced in 1983 and discontinued about twenty years later.
Louis Ducos du Hauron had suggested using a sandwich of three differently color-recording emulsions on transparent supports which could be exposed together in an ordinary camera, then taken apart and used like any other set of three-color separations. The problem was that although two of the emulsions could be in contact face-to-face, the third would have to be separated by the thickness of one transparent support layer. Because all silver halide emulsions are inherently sensitive to blue, the blue-recording layer ought to be on top and have a blue-blocking yellow filter layer behind it. This blue-recording layer, used to make the yellow print which could most afford to be "soft", would end up producing the sharpest image. The two layers behind it, one sensitized to red but not green and the other to green but not red, would suffer from scattering of the light as it passed through the topmost emulsion, and one or both would further suffer by being spaced away from it.
Despite these limitations, some "tripacks" were commercially produced, such as the Hess-Ives "Hiblock" which sandwiched an emulsion on film between emulsions coated on glass plates. For a brief period in the early 1930s, the American Agfa-Ansco company produced Colorol, a roll-film tripack for snapshot cameras. The three emulsions were on unusually thin film bases. After exposure, the roll was sent to Agfa-Ansco for processing and the triple negatives were returned to the customer with a set of color prints. The images were not sharp and the color was not very good, but they were genuine "natural color" snapshots.
"Bipacks" using only two emulsions face-to-face were the subject of some development. Although the range of colors which could be reproduced by only two components was limited, skin tones and most hair and eye colors could be rendered with surprising fidelity, making bipack processes a viable option for color portraiture. In commercial practice, however, the use of bipacks was almost entirely confined to two-color motion picture systems.
If the three layers of emulsion in a tripack did not have to be taken apart in order to produce the cyan, magenta and yellow dye images from them, they could be coated directly on top of each other, eliminating the most serious problems. In fact, some chemical magic was under development which would make that possible.
In 1935, American Eastman Kodak introduced the first modern "integral tripack" color film and called it Kodachrome, a name recycled from an earlier and completely different two-color process. Its development was led by the improbable team of Leopold Mannes and Leopold Godowsky, Jr. (nicknamed "Man" and "God"), two highly regarded classical musicians who had started tinkering with color photographic processes and ended up working with the Kodak Research Laboratories. Kodachrome had three layers of emulsion coated on a single base, each layer recording one of the three additive primaries, red, green, and blue. In keeping with Kodak's old "you press the button, we do the rest" slogan, the film was simply loaded into the camera, exposed in the ordinary way, then mailed to Kodak for processing. The complicated part, if the complexities of manufacturing the film are ignored, was the processing, which involved the controlled penetration of chemicals into the three layers of emulsion. Only a simplified description of the process is appropriate in a short history: as each layer was developed into a black-and-white silver image, a "dye coupler" added during that stage of development caused a cyan, magenta or yellow dye image to be created along with it. The silver images were chemically removed, leaving only the three layers of dye images in the finished film.
Initially, Kodachrome was available only as 16mm film for home movies, but in 1936 it was also introduced as 8mm home movie film and short lengths of 35mm film for still photography. In 1938, sheet film in various sizes for professional photographers was introduced, some changes were made to cure early problems with unstable colors, and a somewhat simplified processing method was instituted.
In 1936, the German Agfa followed with their own integral tripack film, Agfacolor Neu, which was generally similar to Kodachrome but had one important advantage: Agfa had found a way to incorporate the dye couplers into the emulsion layers during manufacture, allowing all three layers to be developed at the same time and greatly simplifying the processing. Most modern color films, excepting the now-discontinued Kodachrome, use the incorporated dye coupler technique, but since the 1970s nearly all have used a modification developed by Kodak rather than the original Agfa version.
In 1941, Kodak made it possible to order prints from Kodachrome slides. The print "paper" was actually a white plastic coated with a multilayer emulsion similar to that on the film. These were the first commercially available color prints created by the chromogenic dye coupler method. In the following year, Kodacolor film was introduced. Unlike Kodachrome, it was designed to be processed into a negative image which showed not only light and dark reversed but also complementary colors. The use of such a negative for making prints on paper simplified the processing of the prints, reducing their cost.
The expense of color film as compared to black-and-white and the difficulty of using it with indoor lighting combined to delay its widespread adoption by amateurs. In 1950, black-and-white snapshots were still the norm. By 1960, color was much more common but still tended to be reserved for travel photos and special occasions. Color film and color prints still cost several times as much as black-and-white, and taking color snapshots in deep shade or indoors required the use of flashbulbs, an inconvenience and an additional expense. By 1970, prices were coming down, film sensitivity had been improved, electronic flash units were replacing flashbulbs, and in most families color had become the norm for snapshot-taking. Black-and-white film continued to be used by some photographers who preferred it for aesthetic reasons or who wanted to take pictures by existing light in low-light conditions, which was still difficult to do with color film. They usually did their own developing and printing. By 1980, black-and-white film in the formats used by typical snapshot cameras, as well as commercial developing and printing service for it, had nearly disappeared.
Instant color film was introduced by Polaroid in 1963. Like Polaroid's contemporary instant black-and-white film, their first color product was a negative-positive peel-apart process which produced a unique print on paper. The negative could not be reused and was discarded. The blight created by carelessly discarded caustic-chemical-laden Polaroid negatives, which tended to accumulate most heavily at the prettiest, most snapshot-worthy locations, horrified Polaroid founder Edwin Land and prompted him to develop the later SX-70 system, which produced no separate negative to discard.
Some currently available color films are designed to produce positive transparencies for use in a slide projector or magnifying viewer, although paper prints can also be made from them. Transparencies are preferred by some professional photographers who use film because they can be judged without having to print them first. Transparencies are also capable of a wider dynamic range, and therefore of a greater degree of realism, than the more convenient medium of prints on paper. The early popularity of color "slides" among amateurs went into decline after the introduction of automated printing equipment started bringing print quality up and prices down.
Other currently available films are designed to produce color negatives for use in creating enlarged positive prints on color photographic paper. Color negatives may also be digitally scanned and then printed by non-photographic means or viewed as positives electronically. Unlike reversal-film transparency processes, negative-positive processes are, within limits, forgiving of incorrect exposure and poor color lighting, because a considerable degree of correction is possible at the time of printing. Negative film is therefore more suitable for casual use by amateurs. Virtually all single-use cameras employ negative film. Photographic transparencies can be made from negatives by printing them on special "positive film", but this has always been unusual outside of the motion picture industry and commercial service to do it for still images may no longer be available. Negative films and paper prints are by far the most common form of color film photography today.
After a transition period centered around 1995–2005, color film was relegated to a niche market by inexpensive multi-megapixel digital cameras which can shoot both in monochrome as well as color. Film continues to be the preference of some photographers because of its distinctive "look" and fondness of the format.
Photographers differed in opinion about color photography when it was first introduced. Some fully embraced it when it was available to the public in the late 1930s, while others remained skeptical of its relevance in the art of photography.
Ferenc Berko, a classic photographer who lived during the rise of color film, was one of the photographers who immediately recognized the potential of color film. He saw it as a new way to frame the world; a way to experiment with the subjects he photographed and how he conveyed emotion in the photograph.
John Hedgecoe, another photographer who lived during this time period, was another example of those who preferred color. He published a book entitled The Art of Color Photography, in which he explained the importance of understanding the "special and often subtle relationships between different colors". He also described the psychological and emotional power that color can have on the viewer, since certain colors, he argues, can make people feel a certain way.
Jan Groover, a postmodernist noted for her work during the 1970s used color extensively in her work.
Though color photography had its followers, black-and-white still remained the more popular and respected film when color first came out.
Harold Baquet, for instance—a relatively current photographer known best for documenting New Orleans civil rights—was not keen on color. He preferred to take pictures mainly using black-and-white film. When asked about his reasoning for this preference during an interview, he replied “The less is more thing. Sometimes the color distracts from the essential subject. Sometimes, just light, line and form is enough, and it allows you to explore the sculptural qualities of that third dimension, that illusional dimension of depth. And it’s fun”. This aversion to color was due mainly to a fear of losing simplicity in his pictures. He worried that color gave the eye too much to take in.
This worry was not uncommon. Photographer Ansel Adams, known best for his dramatic black-and-white landscapes, also felt that color could be distracting, and could therefore divert the artist's attention away from creating a photograph to his full potential, according to some experts. Adams actually claimed that he could get "a far greater sense of 'color' through a well-planned and executed black-and-white image than [he had] ever achieved with color photography". Another expert source mentioned that Adams was a "master of control". He wrote books about technique, developed the Zone System—which helped determine the optimal exposure and development time for a given photograph—and introduced the idea of "previsualization", which involved the photographer imagining what he wanted his final print to look like before he even took the shot. These concepts and methods allowed for nearly total control of all the potential variables that factor into a final print. Because of this love for control, Adams disliked color because it lacked this element that he had mastered with black-and-white.
While Adams initially was far from thrilled with color, he did experiment with it, unknown to many. A few examples of his color work are available in the online archive of the Center for Creative Photography at the University of Arizona. His subjects that he shot in color ranged from portraits to landscape to architecture; a similar scope to that of his black and white work. In fact, toward the end of his life, Adams admitted his regret of not being able to master the technique of color, according to an expert source.
Though a wide range of film preference still exists among photographers today, color has, with time, gained a much larger following as well as a higher level of respect in the field of photography as a whole.
Experimentation with creating photographs that mirrored the colors of real life began in the 1840s. Each process may require different methods of preservation.
Color photographic materials are impermanent and are by nature unstable. Chromogenic color photographs, for example, are composed of yellow, magenta, and cyan organic dyes, which fade at different rates. Even when in dark storage and enclosed in the proper archival materials, deterioration is unavoidable. However, when given the proper preservation care, fading, color shifting, and discoloration can be delayed.
Numerous factors can deteriorate and even destroy photographs. Some examples include:
Three signs of age that affect color photography are:
In general, the colder the storage, the longer the "life" of color photographs. Frost-free refrigeration, more commonly known as cold storage (below freezing) is one of the most effective ways to bring a halt to developing damage to color photographic materials. Selecting this type of storage environment is costly and requires special training to remove and return items. Therefore, cool storage (above freezing) is more common and less costly, which requires that the temperature is consistently between 10–15 °C (50–59 °F) with 30–40% relative humidity with special attention to dew point to eliminate concerns for condensation. General dark storage in light tight enclosures and storage boxes is always advised for individual items. When materials are exposed to light during handling, usage, or display, light sources should be UV-filtered and intensity kept at minimum. In storage areas, 200–400 lux is recommended.
The usage of enclosures is the easiest method of preserving photographic materials from being damaged through handling and light exposure. All protective materials should pass the Photographic Activity Test (PAT) as described both by the American National Standards Institute (ANSI) in standard IT9.2–1988, and the International Organization for Standardization (ISO) in standard 18916:2007(E), Photography – Processed Photographic Materials – Photographic Activity Test for Enclosure Materials. The PAT is an archival science test that determines what kind of enclosures will preserve, prevent, and/or prolong from further deterioration while in storage.
The recommended use of archival enclosures includes each item having its own enclosure and that each enclosure is of the appropriate size. Archival enclosures may come in two different forms: paper or plastic. Choosing either option has its advantages and disadvantages.
After photographic materials are individually enclosed, housing or storage containers provide another protective barrier such as folders and boxes made from archival paperboard as addressed in ISO Standards 18916:2007 and 18902. Sometimes these containers have to be custom-made in order to properly store odd sizes. In general, flat storage in boxes is recommended because it provides more stable support, particularly for materials that are in more fragile condition. Still, boxes and folders should never be over-filled with materials.
Suspended nanoparticles in the glass prevent U.V light from causing chemical reactions that change image colors. For this reason stained glass is being used to capture true color images of Mars for the 2019 ESA Mars rover mission.
The Autochrome Lumière is an early color photography process patented in 1903 by the Lumière brothers in France and first marketed in 1907. It was the principal color photography process in use before the advent of subtractive color film in the mid-1930s. Prior to the Lumiere brothers, Louis Ducos du Hauron utilized the separation technique to create colour images on paper with screen plates, producing natural colours through superimposition, which would become the foundation of all commercial colour photography. Descendents of photographer Antoine Lumiere, inventors Louis and Auguste Lumiere utilized Du Hauron's (1869) technique, which had already been improved upon by other inventors such as John Joly (1894) and James William McDonough (1896), making it possible to print photographic images in colour. The most broadly used form of colour photography in the early twentieth century, autochrome was cherished for its aesthetic appeal and uniqueness, which have also become its most recognizable characteristics.Autumn in New England
The autumn in New England marks the transition from summer to winter in New England, United States. The autumn color of trees in New England has been said to be some of the most brilliant color in the United States. Travelers from many areas of the USA and even Europe flock to Vermont, New Hampshire, Maine, and parts of Massachusetts to see the colors each fall. Hiking has become popular among the tourists, and several areas offer guided tours.The combination of the natural rugged landscape with the rural and small town villages has made several areas in New England iconic in terms of fall color photography. The numerous barns, church buildings, farmhouses, and villages combined with the bright oranges, reds, and yellows makes for iconic foliage photographs.Chromogenic
Chromogenic refers to photographic processes that work by forming a conventional silver image and then replacing it with a dye image. Most films and papers used for color photography today are chromogenic.Chromogenic print
A chromogenic print, also known as a silver halide print, or a dye coupler print, is a photographic print made from a color negative, transparency, or digital image, and developed using a chromogenic process. They are composed of three layers of gelatin, each containing an emulsion of silver halide, which is used as a light-sensitive material, and a different dye coupler of subtractive color which together, when developed, form a full-color image.Darkroom
A darkroom is a workshop used by photographers working with photographic film to make prints and carry out other associated tasks. It is a room that can be made completely dark to allow the processing of the light-sensitive photographic materials, including film and photographic paper. Various equipment is used in the darkroom, including an enlarger, baths containing chemicals, and running water.
Darkrooms have been used since the inception of photography in the early 19th century. Darkrooms have many various manifestations, from the elaborate space used by Ansel Adams to a retooled ambulance wagon used by Timothy H. O'Sullivan. From the initial development of the film to the creation of prints, the darkroom process allows complete control over the medium.
Due to the popularity of color photography and complexity of processing color film (see C-41 process) and printing color photographs and also to the rise, first of Polaroid technology and later digital photography, darkrooms are decreasing in popularity, though are still commonplace on college campuses, schools and in the studios of many professional photographers.
Other applications of darkrooms include the use in nondestructive testing, such as magnetic particle inspection.Dye coupler
Dye coupler is present in chromogenic film and paper used in photography, primarily color photography. When color developer reduces ionized (exposed) silver-halide crystals, the developer is oxidized, and the oxidized molecules react with dye coupler molecules to form dye in situ. The silver image is removed by subsequent bleach and fix processes, so the final image will consist of the dye image.
Dye coupler technology has seen considerable advancement since the beginning of modern color photography. Major film and paper manufacturers have continually improved the stability of the image dye by improving couplers, particularly since the 1980s, so that archival properties of images are enhanced in newer color papers and films. Generally speaking, dye couplers for paper use are given more emphasis on the image permanence than those for film use, but some modern films (such as Fujichrome Provia films) use variants of couplers that were originally designed for paper use to further improve the image permanence.Eric Meola
Eric Meola (born 1946 in Syracuse, New York) is an American photographer. He graduated from Syracuse University in 1968 and is self-taught in the art of photography. In New York he apprenticed under photographer Pete Turner, who influenced Meola's use of saturated color and graphic design. In 1971, Meola opened a studio and began working for popular magazines such as Life, Esquire, and Time, shooting editorial photos. His work has since appeared in museum collections including the National Portrait Gallery in Washington, DC, and in Munich's Museum of Modern Art. Meola's official website can be found below.
Meola has traveled throughout the world, and is recognized for the brilliant use of color in his photography. One of his most famous photos, Coca(Cola) Kid, was taken in Haiti. This photo appeared in the 1997 issue of Life magazine as one of the "100 Magnificent Moments of the Past 1,000 Years". Meola is also known for his photos of Bruce Springsteen, including the cover of Springsteen's album Born to Run. Several of Meola's Springsteen photographs appear in the thirtieth anniversary box-set edition of Darkness on the Edge of Town. Meola's clients include American Express, Jeep, AT&T, Porsche and BMW.
Meola received a Clio Award for his Timberland campaign and won "Photographer of the Year" from the American Society of Media Photographers.
He has published several books; Last Places on Earth, published in 2004, and Born to Run: The Unseen Photos, published in 2006. In October 2008, a new, 272-page book entitled India: in Word and Image from Welcome Books compiles his color photography of India. Reviewer Pete Turner says, "Eric…has brought back a vision of color unmatched anywhere on earth." Meola was among the 43 noted photographers invited to donate a print to "FOCUS: an auction of the finest photography to benefit City Harvest...." The fund-raiser on September 18, 2008 supported City Harvest, a food collection bank in New York City. Ernst Haas
For the political scientist, see Ernst B. Haas and for Swiss rower see Ernst Haas (rower).Ernst Haas (March 2, 1921 – September 12, 1986) was an Austrian-American photojournalist and color photographer. During his 40-year career, Haas bridged the gap between photojournalism and the use of photography as a medium for expression and creativity. In addition to his coverage of events around the globe after World War II, Haas was an early innovator in color photography. His images were disseminated by magazines like Life and Vogue and, in 1962, were the subject of the first single-artist exhibition of color photography at New York's Museum of Modern Art. He served as president of the cooperative Magnum Photos, and his book The Creation (1971) was one of the most successful photography books ever, selling 350,000 copies.Image editing
Image editing encompasses the processes of altering images, whether they are digital photographs, traditional photo-chemical photographs, or illustrations. Traditional analog image editing is known as photo retouching, using tools such as an airbrush to modify photographs, or editing illustrations with any traditional art medium. Graphic software programs, which can be broadly grouped into vector graphics editors, raster graphics editors, and 3D modelers, are the primary tools with which a user may manipulate, enhance, and transform images. Many image editing programs are also used to render or create computer art from scratch.Joseph A. Ball
Joseph Arthur Ball (August 16, 1894 – August 27, 1951) was an American inventor, physicist, and executive at Technicolor. He was the technical director of the first color movie Becky Sharp, and a recipient of an Academy Honorary Award at the 11th Academy Awards for his contributions to color film photography. He held many patents in color photography and was credited with creating the three-component process.Kodachrome
Kodachrome is a brand name for a non-substantive, color reversal film introduced by Eastman Kodak in 1935. It was one of the first successful color materials and was used for both cinematography and still photography. For many years Kodachrome was widely used for professional color photography, especially for images intended for publication in print media. Because of its complex processing requirements, the film was sold process-paid in the United States until 1954 when a legal ruling prohibited this. Elsewhere, this arrangement continued.
Due to the growth and popularity of alternative photographic materials, its complex processing requirements, and the widespread transition to digital photography, Kodachrome lost market share. Its manufacture was discontinued in 2009, and processing ended in December 2010.
In early 2017, Kodak announced they were investigating the possibility of reintroducing Kodachrome, but later conceded that this was unlikely to happen.Louis Arthur Ducos du Hauron
Louis Arthur Ducos du Hauron (8 December 1837 – 31 August 1920) was a French pioneer of color photography. He was born in Langon, Gironde and died in Agen.
After writing an unpublished paper setting forth his basic concepts in 1862, he worked on developing practical processes for color photography on the three-color principle, using both additive and subtractive methods. In 1868 he patented his ideas and in 1869 he published them in Les couleurs en photographie, solution du problème. The discovery of dye sensitization by Hermann Wilhelm Vogel in 1873 greatly facilitated the initial three-color analysis on which all of Ducos de Hauron's methods depended.The most widely reproduced of his surviving color photographs is the View of Agen, an 1877 image of a landscape in southern France, printed by the subtractive assembly method he pioneered. Several different photographs of the view from his attic window, one dated 1874, also survive, as do later views taken in Algeria, still life subjects, reproductions of paintings and art prints, and at least two portraits of uncertain date.
In 1891, he introduced the anaglyph stereoscopic print, the "red and blue glasses" type of 3-D print. Although others had earlier applied the same principle to drawings or used it to project images onto a screen, he was the first to reproduce stereoscopic photographs in the convenient form of anaglyph prints on paper.Love (magazine)
Love is a bi-annual British style magazine founded in 2009 by stylist and fashion journalist Katie Grand, who remains editor-in-chief. Since 2012, Lulu Kennedy has been editor-at-large and Alex Fury has been editor of this Condé Nast publication. Suzanne Weinstock of the Columbia University Graduate School of Journalism described the magazine this way in 2010:
Despite its glossy pages, the magazine has a raw look. Black-and-white photography dominates, and most of the color photography has a muted palette, as if the pictures have aged and faded. Some images are clearly fashion photography; others are more like inventive snapshots. Nudity is plentiful in many styles, from the grittily pornographic to the breathtakingly artistic.
The first cover in 2009 featured American singer-songwriter Beth Ditto, naked. Later covers have featured Madonna, Cher, Kate Moss, Miley Cyrus, Lea T, Justin Bieber, and even (for the tenth issue) Minnie Mouse.Luis Marden
Luis Marden (born Annibale Luigi Paragallo) (January 25, 1913 – March 3, 2003) was an American photographer, explorer, writer, filmmaker, diver, navigator, and linguist who worked for National Geographic Magazine. He worked as a photographer and reporter before serving as chief of the National Geographic foreign editorial staff. He was a pioneer in the use of color photography, both on land and underwater, and also made many discoveries in the world of science.
His polymathic nature has led many to consider him the epitome of the "National Geographic man," the old-time adventurer who trekked to the edges of the globe in search of material for the magazine's longer articles. Though he had officially retired in 1976, Marden continued to write occasional stories long after. He wrote more than 60 articles for the magazine.Photograph
A photograph (also known as a photo) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography. The word photograph was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (phos), meaning "light," and γραφή (graphê), meaning "drawing, writing," together meaning "drawing with light."Sarah Angelina Acland
Sarah Angelina ("Angie") Acland (26 June 1849 – 2 December 1930) was an English amateur photographer, known for her portraiture and as a pioneer of colour photography. She was credited by her contemporaries with inaugurating colour photography "as a process for the travelling amateur", by virtue of the photographs she took during two visits to Gibraltar in 1903 and 1904.Sergey Prokudin-Gorsky
Sergey Mikhaylovich Prokudin-Gorsky (Russian: Серге́й Миха́йлович Проку́дин-Го́рский, listen ; August 30 [O.S. August 18] 1863 – September 27, 1944) was a Russian chemist and photographer. He is best known for his pioneering work in colour photography and his effort to document early 20th-century Russia.Using a railroad-car darkroom provided by Tsar Nicholas II, Prokudin-Gorsky traveled the Russian Empire from around 1909 to 1915 using his three-image colour photography to record its many aspects. While some of his negatives were lost, the majority ended up in the U.S. Library of Congress after his death. Starting in 2000, the negatives were digitised and the colour triples for each subject digitally combined to produce hundreds of high-quality colour images of century-ago Russia.The Terror of the Tongs
The Terror of the Tongs is a 1961 Hammer Film directed by Anthony Bushell and starring Geoffrey Toone, Christopher Lee and Yvonne Monlaur.
The low-budget Hammer film is distinguished by good color photography and a strong performance by Christopher Lee as Chung King, the aphorism-quoting leader of the Hong Kong division of the Red Dragon Tong.Zond 7
Zond 7, a formal member of the Soviet Zond program and unmanned version of Soyuz 7K-L1 manned moon-flyby spacecraft, the first truly successful test of L1, was launched towards the Moon from a mother spacecraft (69-067B) on a mission of further studies of the Moon and circumlunar space, to obtain color photography of Earth and the Moon from varying distances, and to flight test the spacecraft systems. Earth photos were obtained on August 9, 1969. On August 11, 1969, the spacecraft flew past the Moon at a distance of 1984.6 km and conducted two picture taking sessions. Zond 7 reentered Earth's atmosphere on August 14, 1969, and achieved a soft landing in a preset region south of Kustanai, Kazakhstan.
Like other Zond circumlunar craft, Zond 7 used a relatively uncommon technique called skip reentry to shed velocity upon returning to Earth.
Of all circumlunar Zond craft launches, Zond 7 would have been the first to make a safe flight for a crew had it been manned.
The return capsule is on display at the Orevo Facility of Bauman University in Dmitrov, Russia.
