In partnership with [[Louis Daguerre]], he worked out post-exposure processing methods that produced visually superior results and replaced the bitumen with a more light-sensitive resin, but hours of exposure in the camera were still required. With an eye to eventual commercial exploitation, the partners opted for total secrecy. [197] => [198] => Niépce died in 1833 and Daguerre then redirected the experiments toward the light-sensitive [[silver halide]]s, which Niépce had abandoned many years earlier because of his inability to make the images he captured with them light-fast and permanent. Daguerre's efforts culminated in what would later be named the [[daguerreotype]] process. The essential elements—a silver-plated surface sensitized by [[iodine]] vapor, developed by [[Mercury (element)|mercury]] vapor, and "fixed" with hot saturated [[sodium chloride|salt]] water—were in place in 1837. The required exposure time was measured in minutes instead of hours. Daguerre took the earliest confirmed photograph of a person in 1838 while capturing a view of a Paris street: unlike the other pedestrian and horse-drawn traffic on the busy boulevard, which appears deserted, one man having his boots polished stood sufficiently still throughout the several-minutes-long exposure to be visible. The existence of Daguerre's process was publicly announced, without details, on 7 January 1839. The news created an international sensation. France soon agreed to pay Daguerre a pension in exchange for the right to present his invention to the world as the gift of France, which occurred when complete working instructions were unveiled on 19 August 1839.

After reading about Daguerre's invention in January 1839, Talbot published his hitherto secret method and set about improving on it. At first, like other pre-daguerreotype processes, Talbot's paper-based photography typically required hours-long [[exposures]] in the camera, but in 1840 he created the [[calotype]] process, which used the [[photographic processing|chemical development]] of a [[latent image]] to greatly reduce the exposure needed and compete with the daguerreotype. In both its original and calotype forms, Talbot's process, unlike Daguerre's, created a translucent [[negative (photography)|negative]] which could be used to print multiple positive copies; this is the basis of most modern chemical photography up to the present day, as daguerreotypes could only be replicated by rephotographing them with a camera.[https://www.bbc.co.uk/history/historic_figures/fox_talbot_william_henry.shtml William Henry Fox Talbot (1800–1877)] {{Webarchive|url=https://web.archive.org/web/20101003154557/http://www.bbc.co.uk/history/historic_figures/fox_talbot_william_henry.shtml |date=3 October 2010}}.

Although the convenience of the film greatly popularized amateur photography, early films were somewhat more expensive and of markedly lower optical quality than their glass plate equivalents, and until the late 1910s they were not available in the large formats preferred by most professional photographers, so the new medium did not immediately or completely replace the old.

This provides the photographer with the three basic channels required to recreate a color image. Transparent prints of the images could be projected through similar color filters and superimposed on the projection screen, an [[additive color|additive method]] of color reproduction. A color print on paper could be produced by superimposing [[carbon print]]s of the three images made in their [[complementary color]]s, a [[subtractive color|subtractive method]] of color reproduction pioneered by [[Louis Ducos du Hauron]] in the late 1860s. [306] => [[File:Colonel William Willoughby Verner, Sanger Shepherd process, by Sarah Acland 1903.png|thumb|left|Color photography was possible long before [[Kodachrome]], as this 1903 portrait by [[Sarah Angelina Acland]] demonstrates, but in its earliest years, the need for special equipment, long exposures, and complicated printing processes made it extremely rare.]] [307] => Russian photographer [[Sergei Mikhailovich Prokudin-Gorskii]] made extensive use of this color separation technique, employing a special camera which successively exposed the three color-filtered images on different parts of an oblong [[photographic plate|plate]]. Because his exposures were not simultaneous, unsteady subjects exhibited color "fringes" or, if rapidly moving through the scene, appeared as brightly colored ghosts in the resulting projected or printed images. [308] => [309] => Implementation of color photography was hindered by the limited sensitivity of early photographic materials, which were mostly sensitive to blue, only slightly sensitive to green, and virtually insensitive to red. The discovery of dye sensitization by photochemist [[Hermann W. Vogel|Hermann Vogel]] in 1873 suddenly made it possible to add sensitivity to green, yellow and even red. Improved color sensitizers and ongoing improvements in the overall sensitivity of [[Photographic emulsion|emulsions]] steadily reduced the once-prohibitive long exposure times required for color, bringing it ever closer to commercial viability. [310] => [311] => [[Autochrome]], the first commercially successful color process, was introduced by the [[Auguste and Louis Lumière|Lumière brothers]] in 1907. Autochrome [[photographic plate|plates]] incorporated a [[mosaic]] color filter layer made of dyed grains of [[potato starch]], which allowed the three color components to be recorded as adjacent microscopic image fragments. After an Autochrome plate was [[reversal film|reversal processed]] to produce a positive [[reversal film|transparency]], the starch grains served to illuminate each fragment with the correct color and the tiny colored points blended together in the eye, synthesizing the color of the subject by the [[additive color|additive method]]. Autochrome plates were one of several varieties of additive color screen plates and films marketed between the 1890s and the 1950s. [312] => [313] => [[Kodachrome]], the first modern "integral tripack" (or "monopack") color film, was introduced by [[Kodak]] in 1935. It captured the three color components in a multi-layer [[Photographic emulsion|emulsion]]. One layer was sensitized to record the red-dominated part of the [[visible spectrum|spectrum]], another layer recorded only the green part and a third recorded only the blue. Without special [[film processing]], the result would simply be three superimposed black-and-white images, but [[complementary color|complementary]] cyan, magenta, and yellow dye images were created in those layers by adding [[color coupler]]s during a complex processing procedure. [314] => [315] => [[Agfa-Gevaert|Agfa's]] similarly structured [[Agfacolor]] Neu was introduced in 1936. Unlike Kodachrome, the color couplers in Agfacolor Neu were incorporated into the emulsion layers during manufacture, which greatly simplified the processing. Currently, available color films still employ a multi-layer emulsion and the same principles, most closely resembling Agfa's product. [316] => [317] => [[Instant film|Instant color film]], used in a special camera which yielded a unique finished color print only a minute or two after the exposure, was introduced by [[Polaroid Corporation|Polaroid]] in 1963. [318] => [319] => [[Color photography]] may form images as positive transparencies, which can be used in a [[slide projector]], or as color negatives intended for use in creating positive color enlargements on specially coated paper. The latter is now the most common form of film (non-digital) color photography owing to the introduction of automated photo printing equipment. After a transition period centered around 1995–2005, color film was relegated to a niche market by inexpensive multi-megapixel digital cameras.

In this light, money could be paid for the subject of the photograph or the photograph itself. The commercial photographic world could include: [457] => * Advertising photography: There are photographs made to illustrate and usually sell a service or product. These images, such as [[packshot]]s, are generally done with an [[advertising agency]], [[design firm]] or with an in-house corporate design team. [458] => * [[Architectural photography]] focuses on capturing photographs of buildings and architectural structures that are aesthetically pleasing and accurate in terms of representations of their subjects. [459] => * [[Event photography]] focuses on photographing guests and occurrences at mostly social events. [460] => * Fashion and glamour photography usually incorporates [[photographic model|models]] and is a form of advertising photography. [[Fashion photography]], like the work featured in ''[[Harper's Bazaar]]'', emphasizes clothes and other products; glamour emphasizes the model and body form while glamour photography is popular in advertising and [[men's magazine]]s. Models in [[glamour photography]] sometimes work [[Nude photography|nude]]. [461] => * [[360 product photography]] displays a series of photos to give the impression of a rotating object. This technique is commonly used by ecommerce websites to help shoppers visualise products. [462] => * [[Concert photography]] focuses on capturing candid images of both the artist or band as well as the atmosphere (including the crowd). Many of these photographers work freelance and are contracted through an artist or their management to cover a specific show. Concert photographs are often used to promote the artist or band in addition to the venue. [463] => * [[Crime scene photography]] consists of photographing scenes of crime such as robberies and murders. A black and white camera or an [[infrared camera]] may be used to capture specific details. [464] => * [[Still life photography]] usually depicts inanimate subject matter, typically commonplace objects which may be either natural or man-made. Still life is a broader category for food and some natural photography and can be used for advertising purposes. [465] => * Real estate photography focuses on the production of photographs showcasing a property that is for sale, such photographs requires the use of wide-lens and extensive knowledge in [[high-dynamic-range imaging]] photography. [466] => [[File:Cheese and Tomatoes.jpg|thumb|right|Example of a studio-made food photograph]] [467] => * [[Food photography]] can be used for editorial, packaging or advertising use.

In the United States, a handful of photographers, including [[Alfred Stieglitz]], [[Edward Steichen]], [[John Szarkowski]], [[F. Holland Day]], and [[Edward Weston]], spent their lives advocating for photography as a fine art. [479] => At first, fine art photographers tried to imitate painting styles. This movement is called [[Pictorialism]], often using [[soft focus]] for a dreamy, 'romantic' look. In reaction to that, Weston, [[Ansel Adams]], and others formed the [[Group f/64]] to advocate '[[straight photography]]', the photograph as a (sharply focused) thing in itself and not an imitation of something else. [480] => [481] => The [[aesthetics]] of photography is a matter that continues to be discussed regularly, especially in artistic circles. Many artists argued that photography was the mechanical reproduction of an image. If photography is authentically art, then photography in the context of art would need redefinition, such as determining what component of a photograph makes it [[beauty|beautiful]] to the viewer. The controversy began with the earliest images "written with light"; [[Nicéphore Niépce]], [[Louis Daguerre]], and others among the very earliest photographers were met with acclaim, but some questioned if their work met the definitions and purposes of art.

It is now usually understood to refer only to still images, but in some cases the term also refers to video used in broadcast journalism. Photojournalism is distinguished from other close branches of photography (e.g., [[documentary photography]], social documentary photography, [[street photography]] or [[celebrity photography]]) by complying with a rigid ethical framework which demands that the work be both honest and impartial whilst telling the story in strictly journalistic terms. Photojournalists create pictures that contribute to the news media, and help communities connect with one other. Photojournalists must be well informed and knowledgeable about events happening right outside their door.

(1977) ''[[On Photography]]'', Penguin, London, pp. 3–24, {{ISBN|0-312-42009-9}}. Photographers decide what to take a photo of, what elements to exclude and what angle to frame the photo, and these factors may reflect a particular socio-historical context. Along these lines, it can be argued that photography is a subjective form of representation. [622] => [623] => Modern photography has raised a number of concerns on its effect on society. In [[Alfred Hitchcock]]'s ''[[Rear Window]]'' (1954), the camera is presented as promoting voyeurism. 'Although the camera is an observation station, the act of photographing is more than passive observing'. [624] => [625] =>
[626] => The camera doesn't rape or even possess, though it may presume, intrude, trespass, distort, exploit, and, at the farthest reach of metaphor, assassinate – all activities that, unlike the sexual push and shove, can be conducted from a distance, and with some detachment. [627] =>
[628] => [629] => Digital imaging has raised ethical concerns because of the ease of manipulating digital photographs in post-processing. Many [[photojournalists]] have declared they will not [[Image cropping|crop]] their pictures or are forbidden from combining elements of multiple photos to make "[[photomontage]]s", passing them as "real" photographs. Today's technology has made [[image editing]] relatively simple for even the novice photographer. However, recent changes of in-camera processing allow [[Device fingerprint|digital fingerprinting]] of photos to detect tampering for purposes of [[forensic photography]].

Further unease has been caused around cameras in regards to desensitization. Fears that disturbing or explicit images are widely accessible to children and society at large have been raised. Particularly, [[War photography|photos of war]] and [[pornography]] are causing a stir. Sontag is concerned that "to photograph is to turn people into objects that can be symbolically possessed". Desensitization discussion goes hand in hand with debates about censored images.
