In fact, monochrome film stock is now rarely used at the time of shooting, even if the films are intended to be presented theatrically in black-and-white. Movies such as John Boorman’s The General (1998) and Joel Coen’s The Man Who Wasn’t There (2001) were filmed in color despite being presented in black-and-white for artistic reasons. Raging Bull (1980) and Clerks (1994) are two of the few well-known modern films deliberately shot in black-and-white. In the case of Clerks, because of the extremely low budget, the production team could not afford the added costs of shooting in color. Although the difference in film stock price would have been slight, the store’s fluorescent lights could not have been used to light for color. By shooting in black-and-white, the filmmakers did not have to rent lighting equipment.

Film has a number of disadvantages as a scientific detector: it is difficult to calibrate for photometry, it is not re-usable, it requires careful handling (including temperature and humidity control) for best calibration, and the film must physically be returned to the laboratory and processed. Against this, photographic film can be made with a higher spatial resolution than any other type of imaging detector, and, because of its logarithmic response to light, has a wider dynamic range than most digital detectors. For example, Agfa 10E56 holographic film has a resolution of over 4,000 lines/mm—equivalent to a pixel size of 0.125 micrometers—and an active dynamic range of over five orders of magnitude in brightness, compared to typical scientific CCDs that might have pixels of about 10 micrometers and a dynamic range of 3–4 orders of magnitude.[26][not in citation given]

Most modern black-and-white films, called panchromatic films, record the entire visible spectrum.[1]:157 Some films are orthochromatic, recording visible light wavelengths shorter than 590 nanometers,[1]:158 in the blue to green range of the spectrum and are less sensitive to the longer wavelength range (i.e. orange-red) of the visible spectrum.[3] Black-and-white photography is considered by some to be more subtle and interpretive, and less realistic than color photography.[1]:5 Monochrome images are not direct renditions of their subjects, but are abstractions from reality, representing colors in shades of grey. In computer terms, this is often called greyscale.[4] Black-and-white photography is considered by some to add a more emotional touch to the subject, compared with the original colored photography.[5]

Early photographic plates and films were usefully sensitive only to blue, violet and ultraviolet light. As a result, the relative tonal values in a scene registered roughly as they would appear if viewed through a piece of deep blue glass. Blue skies with interesting cloud formations photographed as a white blank. Any detail visible in masses of green foliage was due mainly to the colorless surface gloss. Bright yellows and reds appeared nearly black. Most skin tones came out unnaturally dark, and uneven or freckled complexions were exaggerated. Photographers sometimes compensated by adding in skies from separate negatives that had been exposed and processed to optimize the visibility of the clouds, by manually retouching their negatives to adjust problematic tonal values, and by heavily powdering the faces of their portrait sitters.

In black-and-white photographic film, there is usually one layer of silver halide crystals. When the exposed silver halide grains are developed, the silver halide crystals are converted to metallic silver, which blocks light and appears as the black part of the film negative. Color film has at least three sensitive layers, incorporating different combinations of sensitizing dyes. Typically the blue-sensitive layer is on top, followed by a yellow filter layer to stop any remaining blue light from affecting the layers below. Next comes a green-and-blue sensitive layer, and a red-and-blue sensitive layer, which record the green and red images respectively. During development, the exposed silver halide crystals are converted to metallic silver, just as with black-and-white film. But in a color film, the by-products of the development reaction simultaneously combine with chemicals known as color couplers that are included either in the film itself or in the developer solution to form colored dyes. Because the by-products are created in direct proportion to the amount of exposure and development, the dye clouds formed are also in proportion to the exposure and development. Following development, the silver is converted back to silver halide crystals in the bleach step. It is removed from the film during the process of fixing the image on the film with a solution of ammonium thiosulfate or sodium thiosulfate (hypo or fixer).[3] Fixing leaves behind only the formed color dyes, which combine to make up the colored visible image. Later color films, like Kodacolor II, have as many as 12 emulsion layers,[4] with upwards of 20 different chemicals in each layer.

The progression of lens design for later emulsions is of practical importance when considering the use of old lenses, still often used on large-format equipment; a lens designed for orthochromatic film may have visible defects with a color emulsion; a lens for panchromatic film will be better but not as good as later designs.

Most films are affected by the physics of silver grain activation (which sets a minimum amount of light required to expose a single grain) and by the statistics of random grain activation by photons. The film requires a minimum amount of light before it begins to expose, and then responds by progressive darkening over a wide dynamic range of exposure until all of the grains are exposed, and the film achieves (after development) its maximum optical density.

As a form of censorship when movies and TV series are aired on Philippine television, many gory scenes are shown in black-and-white. Sometimes the exposure of innards or other scenes too bloody or gruesome are also blurred, not just rendered in monochrome, in compliance with Philippine broadcasting standards.

The first practical and commercially successful color “film” was the Lumière Autochrome, a glass plate product introduced in 1907. It was expensive and not sensitive enough for hand-held “snapshot” use. Film-based versions were introduced in the early 1930s and the sensitivity was later improved. These were “mosaic screen” additive color products, which used a simple layer of black-and-white emulsion in combination with a layer of microscopically small color filter elements. The resulting transparencies or “slides” were very dark because the color filter mosaic layer absorbed most of the light passing through. The last films of this type were discontinued in the 1950s, but Polachrome “instant” slide film, introduced in 1983, temporarily revived the technology.

Black and white, often abbreviated B/W or B&W, and hyphenated black-and-white when used as an adjective, is any of several monochrome forms in visual arts.

Likewise, if part of an image receives less than the beginning threshold level of exposure, which depends upon the film’s sensitivity to light—or speed—the film there will have no appreciable image density, and will appear on the print as a featureless black. Some photographers use their knowledge of these limits to determine the optimum exposure for a photograph; for one example, see the Zone System. Most automatic cameras instead try to achieve a particular average density.

The filters used were different for the different film types.

In order to produce a usable image, the film needs to be exposed properly. The amount of exposure variation that a given film can tolerate, while still producing an acceptable level of quality, is called its exposure latitude. Color print film generally has greater exposure latitude than other types of film. Additionally, because print film must be printed to be viewed, after-the-fact corrections for imperfect exposure are possible during the printing process.

Films can be made to record non-visible ultraviolet (UV) and infrared (IR) radiation. These films generally require special equipment; for example, most photographic lenses are made of glass and will therefore filter out most ultraviolet light. Instead, expensive lenses made of quartz must be used. Infrared films may be shot in standard cameras using an infrared band- or long-pass filter, although the infrared focal point must be compensated for.

Instant photography, as popularized by Polaroid, uses a special type of camera and film that automates and integrates development, without the need of further equipment or chemicals. This process is carried out immediately after exposure, as opposed to regular film, which is developed afterwards and requires additional chemicals. See instant film.

Film remained the dominant form of photography until the early 21st century, when advances in digital photography drew consumers to digital formats. The first consumer electronic camera, the Sony Mavica was released in 1981, the first digital camera, the Fuji DS-X released in 1989,[28] coupled with advances in software such as Adobe Photoshop which was released in 1989, improvements in consumer level digital color printers and increasingly widespread computers in households during the late 20th century facilitated uptake of digital photography by consumers.[20] Although modern photography is dominated by digital users, film continues to be used by enthusiasts. Film remains the preference of some photographers because of its distinctive “look”.[a]

Hurter and Driffield began pioneering work on the light sensitivity of photographic emulsions in 1876. Their work enabled the first quantitative measure of film speed to be devised.[13] They developed H&D curves, which are specific for each film and paper. These curves plot the photographic density against the log of the exposure, to determine sensitivity or speed of the emulsion and enabling correct exposure.[14]

In black-and-white still photography, many photographers choose to shoot in solely black-and-white since the stark contrasts enhance the subject matter.

The history of various visual media has typically begun with black and white, and as technology improved, altered to color. However, there are exceptions to this rule, including black-and-white fine art photography and in motion pictures, many art films.

Photographic film is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film.[1]

Over the active dynamic range of most films, the density of the developed film is proportional to the logarithm of the total amount of light to which the film was exposed, so the transmission coefficient of the developed film is proportional to a power of the reciprocal of the brightness of the original exposure. The plot of the density of the film image against the log of the exposure is known as an H&D curve.[14] This effect is due to the statistics of grain activation: as the film becomes progressively more exposed, each incident photon is less likely to impact a still-unexposed grain, yielding the logarithmic behavior. A simple, idealized statistical model yields the equation density = 1 – ( 1 – k) light, where light is proportional to the number of photons hitting a unit area of film, k is the probability of a single photon striking a grain (based on the size of the grains and how closely spaced they are), and density is the proportion of grains that have been hit by at least one photon. The relationship between density and log exposure is linear for photographic films except at the extreme ranges of maximum exposure (D-max) and minimum exposure (D-min) on an H&D curve, so the curve is characteristically S-shaped (as opposed to digital camera sensors which have a linear response through the effective exposure range.[20] The sensitivity (i.e., the ISO speed) of a film can be affected by changing the length or temperature of development, which would move the H&D curve to the left or right (see figure).[21][22]

In a black and white pre-credits opening sequence in the 2006 Bond film, Casino Royale, a young James Bond (played by Daniel Craig) gains his licence to kill and status as a 00 agent by assassinating the traitorous MI6 section chief Dryden at the British Embassy in Prague, as well as his terrorist contact, Fisher, in a bathroom in Lahore. The remainder of the film starting with the opening credits is shown in color.

A film with a particular ISO rating can be push-processed, or “pushed”, to behave like a film with a higher ISO, by developing for a longer amount of time or at a higher temperature than usual.[25]:160 More rarely, a film can be “pulled” to behave like a “slower” film. Pushing generally coarsens grain and increases contrast, reducing dynamic range, to the detriment of overall quality. Nevertheless, it can be a useful tradeoff in difficult shooting environments, if the alternative is no usable shot at all.

Exposure and focusing are difficult when using UV or IR film with a camera and lens designed for visible light. The ISO standard for film speed only applies to visible light, so visual-spectrum light meters are nearly useless. Film manufacturers can supply suggested equivalent film speeds under different conditions, and recommend heavy bracketing (e.g., with a certain filter, assume ISO 25 under daylight and ISO 64 under tungsten lighting). This allows a light meter to be used to estimate an exposure. The focal point for IR is slightly farther away from the camera than visible light, and UV slightly closer; this must be compensated for when focusing. Apochromatic lenses are sometimes recommended due to their improved focusing across the spectrum.

Experiments with color photography began almost as early as photography itself, but the three-color principle underlying all practical processes was not set forth until 1855, not demonstrated until 1861, and not generally accepted as “real” color photography until it had become an undeniable commercial reality in the early 20th century. Although color photographs of good quality were being made by the 1890s, they required special equipment, long exposures, complex printing or display procedures and highly specialized skills, so they were then exceedingly rare.

Monochrome images may be produced in a number of ways. Finding and capturing a scene having only variants of a certain hue, while difficult and uncommon in practice, will result in an image that technically qualifies as a monochrome photo.[7] One can also artificially limit the range of color in a photo to those within a certain hue by using black-and-white film or paper, or by manipulating color images using computer software.

“Color film” in the modern sense of a subtractive color product with a multi-layered emulsion was born with the introduction of Kodachrome for home movies in 1935 and as lengths of 35 mm film for still cameras in 1936.[15] During the next several decades, color remained much more expensive than black-and-white and required much more light, factors which combined to delay its widespread adoption. Decreasing cost and increasing sensitivity gradually overcame these impediments. By the 1970s, color film predominated in the consumer market, while the use of black-and-white film was increasingly confined to photojournalism and fine art photography.

Photographic lenses and equipment are designed around the film to be used. Although the earliest photographic materials were sensitive only to the blue-violet end of the spectrum, partially color-corrected achromatic lenses were normally used, so that when the photographer brought the visually brightest yellow rays to a sharp focus, the visually dimmest but photographically most active violet rays would be correctly focused, too. The introduction of orthochromatic emulsions required the whole range of colors from yellow to blue to be brought to an adequate focus. Most plates and films described as orthochromatic or isochromatic were practically insensitive to red, so the correct focus of red light was unimportant; a red window could be used to view the frame numbers on the paper backing of roll film, as any red light which leaked around the backing would not fog the film; and red lighting could be used in darkrooms. With the introduction of panchromatic film, the whole visible spectrum needed to be brought to an acceptably sharp focus. In all cases a color cast in the lens glass or faint colored reflections in the image were of no consequence as they would merely change the contrast a little. This was no longer acceptable when using color film. More highly corrected lenses for newer emulsions could be used with older emulsion types, but the converse was not true.

Sepia and brown hued images are produced by certain photographic processes such as calotypes and albumen prints, or by the use of toning solutions which convert silver in the image to silver sulphide, imparting the brown or sepia tone. Selenium toner produces a blue-black or purple image, similarly by converting silver into more stable silver selenide.[6] Cyanotypes used iron salts rather than silver salts to create blue and white hued images.[2]

Special films are used for the long exposures required by astrophotography.[27]

Monochrome photography is photography where each position on an image can record and show a different amount of light, but not a different hue. It includes all forms of black-and-white photography, which produce images containing tones of neutral grey ranging from black to white.[1] Other hues besides grey, such as sepia, cyan or brown can also be used in monochrome photography.[2] In the contemporary world, monochrome photography is mostly used for artistic purposes and certain technical imaging applications, rather than for visually accurate reproduction of scenes.

However, black-and-white photography has continued to be a popular medium for art photography, as shown in the picture by the well-known photographer Ansel Adams. This can take the form of black-and-white film or digital conversion to grayscale, with optional digital image editing manipulation to enhance the results. For amateur use certain companies such as Kodak manufactured black-and-white disposable cameras until 2009. Also, certain films are produced today which give black-and-white images using the ubiquitous C41 color process.

Kosmo Foto article on future of film

Since the late 1960s, few mainstream films have been shot in black-and-white. The reasons are frequently commercial, as it is difficult to sell a film for television broadcasting if the film is not in color. 1961 was the last year in which the majority of Hollywood films were released in black and white.[2]

The earliest practical photographic process was the daguerreotype; it was introduced in 1839 and did not use film. The light-sensitive chemicals were formed on the surface of a silver-plated copper sheet.[5] The calotype process produced paper negatives.[6] Beginning in the 1850s, thin glass plates coated with photographic emulsion became the standard material for use in the camera. Although fragile and relatively heavy, the glass used for photographic plates was of better optical quality than early transparent plastics and was, at first, less expensive. Glass plates continued to be used long after the introduction of film, and were used for astrophotography[7] and electron micrography until the early 2000s, when they were supplanted by digital recording methods. Ilford continues to manufacture glass plates for special scientific applications.[8]

Japan-based Fujifilm’s instant film “Instax” cameras and paper have also proven to be very successful, and have replaced traditional photographic films as Fujifilm’s main film products, while they continue to offer traditional photographic films in various formats and types. [33]

In 1894, the Lumière Brothers introduced their Lumière Panchromatic plate, which was made sensitive, although very unequally, to all colors including red. New and improved sensitizing dyes were developed, and in 1902 the much more evenly color-sensitive Perchromo panchromatic plate was being sold by the German manufacturer Perutz. The commercial availability of highly panchromatic black-and-white emulsions also accelerated the progress of practical color photography, which requires good sensitivity to all the colors of the spectrum for the red, green and blue channels of color information to all be captured with reasonable exposure times.

If parts of the image are exposed heavily enough to approach the maximum density possible for a print film, then they will begin losing the ability to show tonal variations in the final print. Usually those areas will be considered overexposed and will appear as featureless white on the print. Some subject matter is tolerant of very heavy exposure. For example, sources of brilliant light, such as a light bulb or the sun, generally appear best as a featureless white on the print.

Most early forms of motion pictures or film were black and white. Some color film processes, including hand coloring were experimented with, and in limited use, from the earliest days of motion pictures. The switch from most films being in black-and-white to most being in color was gradual, taking place from the 1930s to the 1960s. Even when most film studios had the capability to make color films, the technology’s popularity was limited, as using the Technicolor process was expensive and the process cumbersome. For many years, it was not possible for films in color to render realistic hues, thus its use was restricted to historical films or musicals until the 1950s, while many directors preferred to use black-and-white stock. For the years 1940–1966, a separate Academy Award for Best Art Direction was given for black-and-white movies along with one for color.

The first flexible photographic roll film was sold by George Eastman in 1885,[9] but this original “film” was actually a coating on a paper base. As part of the processing, the image-bearing layer was stripped from the paper and attached to a sheet of hardened clear gelatin. The first transparent plastic roll film followed in 1889.[10] It was made from highly flammable nitrocellulose (“celluloid”), now usually called “nitrate film”.

Plot of image density (D) vs. log exposure (H), yields a characteristic S-curve (H&D curve) for each type of film to determine its sensitivity. Changing the emulsion properties or the processing parameters will move the curve to the left or right.

Changing the exposure will move along the curve, helping to determine what exposure is needed for a given film. Note the non-linear response at the far left (“toe”) and right (“shoulder”) of the curve.

In 2013 Ferrania, a Italy-based film manufacturer which ceased production of photographic films between the years 2009 and 2010, was acquired by the new Film Ferrania S.R.L taking over the old company’s manufacturing faacilities, and re-employed some workers who had been laid off 3 years earlier when the company stopped production of film. In November of the same year, the company started a crowdfunding campaign with the goal of raising $250,000 to buy tooling and machines from the old factory, with the intention of putting some of the films that had been discontinued back into production, the campaign succeeded and in October 2014 was ended with over $320,000 being raised.

Although cellulose acetate or “safety film” had been introduced by Kodak in 1908,[11] at first it found only a few special applications as an alternative to the hazardous nitrate film, which had the advantages of being considerably tougher, slightly more transparent, and cheaper. The changeover was completed for X-ray films in 1933, but although safety film was always used for 16 mm and 8 mm home movies, nitrate film remained standard for theatrical 35 mm films until it was finally discontinued in 1951.[12]

Kodak announced on January 5th, 2017, that Ektachrome, one of Kodak’s most well known transparency films that was discontinued between 2012 and 2013, would be reformulated and manufactured once again, in 35mm still and Super 8 motion picture film formats. [32]

The earliest television broadcasts were transmitted in black-and-white, and received and displayed by black-and-white only television sets.[1] Scottish inventor John Logie Baird demonstrated the world’s first color television transmission on July 3, 1928 using a mechanical process. Some color broadcasts in the U.S. began in the 1950s, with color becoming common in western industrialized nations during the late 1960s. In the United States, the Federal Communications Commission (FCC) settled on a color NTSC standard in 1953, and the NBC network began broadcasting a limited color television schedule in January 1954. Color television became more widespread in the U.S. between 1963 and 1967, when major networks like CBS and ABC joined NBC in broadcasting full color schedules. Some TV stations (small and medium) in the US were still broadcasting in B&W until the late 80s to early 90s, depending on network. Canada began airing color television in 1966 while the United Kingdom began to use an entirely different color system from July 1967 known as PAL. The Republic of Ireland followed in 1970. New Zealand began color broadcasting in 1973, and Australia experimented with color television in 1967 but continued to broadcast in black-and-white until 1975, and New Zealand experimented with color broadcasting in 1973 but didn’t convert until 1975. In China, black-and-white television sets were the norm until as late as the 1990s, color TVs not outselling them until about 1989. In 1969, Japanese electronics manufacturers standardized the first format for industrial/non-broadcast videotape recorders (VTRs) called EIAJ-1, which initially offered only black-and-white video recording and playback. While seldom used professionally now, many consumer camcorders have the ability to record in black-and-white.

Film optimized for sensing X-ray radiation is commonly used for medical imaging by placing the subject between the film and a source of X-rays, without a lens, as if a translucent object were imaged by being placed between a light source and standard film. Unlike other types of film, X-ray film has a sensitive emulsion on both sides of the carrier material. This reduces the X-ray exposure for an acceptable image – a desirable feature in medical radiography. The film is usually placed in contact with a thin layer of lead which also enhances its sensitivity.

The concentration of dyes or silver halide crystals remaining on the film after development is referred to as optical density, or simply density; the optical density is proportional to the logarithm of the optical transmission coefficient of the developed film. A dark image on the negative is of higher density than a more transparent image.

The Wizard of Oz (1939) is in color when Dorothy is in Oz, but in black-and-white when she is in Kansas, although the latter scenes were actually in sepia when the film was originally released. The British film A Matter of Life and Death (1946) depicts the other world in black-and-white (a character says “one is starved of Technicolor … up there”), and earthly events in color. Similarly, Wim Wenders’s film Wings of Desire (1987) uses sepia-tone black-and-white for the scenes shot from the angels’ perspective. When Damiel, the angel (the film’s main character), becomes a human the film changes to color, emphasising his new “real life” view of the world.

Despite the fact that digital cameras are currently by far the most commonly used photographic tool, and that the selection of available photographic films is much smaller than it once was, sales of photographic film have been on a steady upward trend, and companies such as Kodak, which declared bankruptcy in early 2012, among other companies have noticed this upward trend, the president of Kodak Alaris’ film, paper and photo chemical’s division Dennis Olbrich has stated that sales of their photographic films have been growing over the past 3 or 4 years, UK-based Ilford have also confirmed this trend, and have conducted extensive research on this subject matter, their research showed that 60% of current film users had only started using film in the past five years, and that 30% of current film users were under 35 years old. [31]

Printing is an ancient art, and color printing has been possible in some ways from the time colored inks were produced. In the modern era, for financial and other practical reasons, black-and-white printing has been very common through the 20th century. However with the technology of the 21st century, home color printers, which can produce color photographs, are common and relatively inexpensive, a technology relatively unimaginable in the mid-20th century.

Most computers had monochrome (black-and-white, black and green, or black and amber) screens until the late 1980s, although some home computers could be connected to television screens to eliminate the extra cost of a monitor. These took advantage of NTSC or PAL encoding to offer a range of colors from as low as 4 (IBM CGA) to 128 (Atari 800) to 4096 (Commodore Amiga). Early videogame consoles such as the Atari 2600 supported both black-and-white and color modes via a switch, as did some of the early home computers; this was to accommodate black-and-white TV sets, which would display a color signal poorly. (Typically a different shading scheme would be used for the display in the black-and-white mode.)

In 1873, Hermann Wilhelm Vogel discovered that the spectral sensitivity could be extended to green and yellow light by adding very small quantities of certain dyes to the emulsion. The instability of early sensitizing dyes and their tendency to rapidly cause fogging initially confined their use to the laboratory, but in 1883 the first commercially dye-sensitized plates appeared on the market. These early products, described as isochromatic or orthochromatic depending on the manufacturer, made possible a more accurate rendering of colored subject matter into a black-and-white image. Because they were still disproportionately sensitive to blue, the use of a yellow filter and a consequently longer exposure time were required to take full advantage of their extended sensitivity.

Layers of 35mm color film: 1. Film base; 2. Subbing layer; 3. Red light sensitive layer; 4. Green light sensitive layer; 5. Yellow filter; 6. Blue light sensitive layer; 7. UV Filter; 8. Protective layer; 9. (Visible light exposing film).

Print film, when developed, yields transparent negatives with the light and dark areas and colors (if color film is used) inverted to their respective complementary colors. This type of film is designed to be printed onto photographic paper, usually by means of an enlarger but in some cases by contact printing.

The paper is then itself developed. The second inversion that results restores light, shade and color to their normal appearance. Color negatives incorporate an orange color correction mask that compensates for unwanted dye absorptions and improves color accuracy in the prints.

Although color processing is more complex and temperature-sensitive than black-and-white processing, the wide availability of commercial color processing and scarcity of service for black-and-white prompted the design of some black-and-white films which are processed in exactly the same way as standard color film.

Color reversal film produces positive transparencies, also known as diapositives. Transparencies can be reviewed with the aid of a magnifying loupe and a lightbox. If mounted in small metal, plastic or cardboard frames for use in a slide projector or slide viewer they are commonly called slides.

Reversal film is often marketed as “slide film”. Large-format color reversal sheet film is used by some professional photographers, typically to originate very-high-resolution imagery for digital scanning into color separations for mass photomechanical reproduction.

Photographic prints can be produced from reversal film transparencies, but positive-to-positive print materials for doing this directly (e.g. Ektachrome paper, Cibachrome/Ilfochrome) have all been discontinued, so that it now requires the use of an internegative to convert the positive transparency image into a negative transparency, which is then printed as a positive print.

[16] Black-and-white reversal film exists but is very uncommon. Conventional black-and-white negative film can be reversal-processed to produce black-and-white slides, as by dr5 Chrome.[17] Although kits of chemicals for black-and-white reversal processing may no longer be available to amateur darkroom enthusiasts, an acid bleaching solution, the only unusual component which is essential, is easily prepared from scratch.

Black-and-white transparencies may also be produced by printing negatives onto special positive print film, still available from some specialty photographic supply dealers.[18]

The films Pleasantville (1998), and Aro Tolbukhin. En la mente del asesino (2002), play with the concept of black-and-white as an anachronism, using it to selectively portray scenes and characters who are either more or less outdated or duller than the characters and scenes shot in full-color. This manipulation of color is utilized in the film Sin City (2005) and the occasional television commercial. The film American History X (1998) is told in a nonlinear narrative in which the portions of the plot that take place “in the past” are shown entirely in black and white, while the “present” storyline’s scenes are displayed in color. In the documentary film Night and Fog (1955) a mix of black-and-white documentary footage is contrasted with color film of the present.

Color images can be converted to black and white on the computer using several methods, including desaturating the existing color RGB image so that no color remains visible (which still allows color channels to be manipulated to alter tones such as darkening a blue sky, or by converting the image to a greyscale version (which eliminates the colors permanently), using software programs like Photoshop.[8] After software conversion to a monochrome image, one or more hues can replace the grey tones to emulate duotones, sepia, selenium or gold toned images or cyanotype, calotype or albumen prints.[2][9]

Black-and-white images are not usually starkly contrasted black and white. They combine black and white in a continuum producing a range of shades of gray. Further, many monochrome prints in still photography, especially those produced earlier in its development, were in sepia (mainly for archival stability), which yielded richer, subtler shading than reproductions in plain black-and-white.

Throughout the 19th century, most photography was monochrome photography: images were either black-and-white or shades of sepia. Occasionally personal and/or commercial photographs might be hand tinted. Color photography was originally rare and expensive and again often containing inaccurate hues. Color photography became more common from the mid-20th century.

Most American newspapers were black-and-white until the early 1980s; The New York Times and The Washington Post remained in black-and-white until the 1990s. Some claim that USA Today was the major impetus for the change to color. In the UK, color was only slowly introduced from the mid-1980s. Even today, many newspapers restrict color photographs to the front and other prominent pages since mass-producing photographs in black-and-white is considerably less expensive than color. Similarly, daily comic strips in newspapers were traditionally black-and-white with color reserved for Sunday strips.:Color printing is more expensive. Sometimes color is reserved for the cover. Magazines such as Jet magazine were either all or mostly black-and-white until the end of the 2000s when it became all-color. Manga (Japanese or Japanese-influenced comics) are typically published in black-and-white although now it is part of its image. Many school yearbooks are still entirely or mostly in black-and-white.

Common film speeds include ISO 25, 50, 64, 100, 160, 200, 400, 800, 1600, 3200, and 6400. Consumer print films are usually in the ISO 100 to ISO 800 range. Some films, like Kodak’s Technical Pan,[24] are not ISO rated and therefore careful examination of the film’s properties must be made by the photographer before exposure and development. ISO 25 film is very “slow”, as it requires much more exposure to produce a usable image than “fast” ISO 800 film. Films of ISO 800 and greater are thus better suited to low-light situations and action shots (where the short exposure time limits the total light received). The benefit of slower film is that it usually has finer grain and better color rendition than fast film. Professional photographers of static subjects such as portraits or landscapes usually seek these qualities, and therefore require a tripod to stabilize the camera for a longer exposure. A professional photographing subjects such as rapidly moving sports or in low-light conditions will inevitably choose a faster film.

In February 2017, Film Ferrania unveiled their “P30” 80 ASA, Panchromatic black and white film, in 35mm format.

The movie Pi is filmed entirely in black-and-white, with a grainy effect until the end.

Some formal photo portraits still use black-and-white. Many visual-art photographers use black-and-white in their work.

Some modern film directors will occasionally shoot movies in black-and-white as an artistic choice, though it is much less common for a major Hollywood production. The use of black-and-white in the mass media often connotes something “nostalgic” or historic. The film director Woody Allen has used black-and-white a number of times since Manhattan (1979), which also had a George Gershwin derived score. The makers of The Good German (2006) used camera lens from the 1940s, and other equipment from that era, so that their black-and-white film imitated the look of early noir.

Film optimized for sensing X-rays and for gamma rays is sometimes used for radiation dosimetry and personal monitoring.

In computing terminology, black-and-white is sometimes used to refer to a binary image consisting solely of pure black pixels and pure white pixels; what would normally be called a black-and-white image, that is, an image containing shades of gray, is referred to in this context as grayscale.[3]

The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can be chemically developed into a visible photograph. In addition to visible light, all films are sensitive to ultraviolet, X-rays and high-energy particles. Unmodified silver halide crystals are sensitive only to the blue part of the visible spectrum, producing unnatural-looking renditions of some colored subjects. This problem was resolved with the discovery that certain dyes, called sensitizing dyes, when adsorbed onto the silver halide crystals made them respond to other colors as well. First orthochromatic (sensitive to blue and green) and finally panchromatic (sensitive to all visible colors) films were developed. Panchromatic film renders all colors in shades of gray approximately matching their subjective brightness. By similar techniques, special-purpose films can be made sensitive to the infrared (IR) region of the spectrum.[2]

However, all of these were glass-based plate products. Panchromatic emulsions on a film base were not commercially available until the 1910s and did not come into general use until much later. Many photographers who did their own darkroom work preferred to go without the seeming luxury of sensitivity to red—a rare color in nature and uncommon even in man-made objects—rather than be forced to abandon the traditional red darkroom safelight and process their exposed film in complete darkness. Kodak’s popular Verichrome black-and-white snapshot film, introduced in 1931, remained a red-insensitive orthochromatic product until 1956, when it was replaced by Verichrome Pan. Amateur darkroom enthusiasts then had to handle the undeveloped film by the sense of touch alone.

DX Encoding (Digital indeX), or DX coding was initially developed by Kodak in the 1980s, and eventually adapted by all camera and film manufacturers.[34] It provides information on both the film cassette and on the film regarding the type of film, number of exposures, speed (ISO/ASA rating) of the film. It consists of three types of identification. First is a barcode near the film opening of the cassette, identifying the manufacturer, film type and processing method (see image below left). This is used by photofinishing equipment during film processing. The second part is a barcode on the edge of the film (see image below right), used also during processing, which indicates the image film type, manufacturer, frame number and synchronizes the position of the frame. The third part of DX coding, known as the DX Camera Auto Sensing (CAS) code, consists of a series of 12 metal contacts on the film cassette, which beginning with cameras manufactured after 1985 could detect the type of film, number of exposures and ISO of the film, and use that information to automatically adjust the camera settings for the speed of the film.[34][35][36]

Film speed describes a film’s threshold sensitivity to light. The international standard for rating film speed is the ISO scale, which combines both the ASA speed and the DIN speed in the format ASA/DIN. Using ISO convention film with an ASA speed of 400 would be labeled 400/27°.[23] A fourth naming standard is GOST, developed by the Russian standards authority. See the film speed article for a table of conversions between ASA, DIN, and GOST film speeds.
