- The chemistry of photography is based on photosensitivity and reactions with light. The chemical processes that create a traditional photograph start inside the camera with the absorption of photons. However, photochemistry alone is not able to produce an image. Development is continued in the darkroom through chemical reactions involving

- There are a variety of chemical compounds that are photosensitive, but the most widely used from the earliest days of photography has been the conversion of silver halides, AgX (X = Cl, Br, I), to produce metallic Ag and X 2. This …

- The Conditions Electron ejected from chlorine (Oxidation): Ag+ + Cl- + light energy → Ag+ + Cl + 1 electron Electron captured by silver (Reduction): Ag+ + 1 electron → Ag (metal) Silver Chloride exposed to UV light Physical …

- All photographic emulsions contain crystals of varying sizes, but within a given emulsion the range is from less than 0.1 micron in slow emulsions (e.g., for paper prints) to a few microns in "fast" negative emulsions.

- The first magical part of photographic chemistry is the photographic emulsion. As you recall, film is made up of a support and an emulsion. The emulsion has two major ingredients: Silver Halide Crystals and Gelatin. The silver halide crystals capture the photographic image. The gelatin holds the silver halide

- The key reactions are outlined below: 1. Forming the image by exposure to light (hυ )_: A very small number of X-ions in the AgX crystals in the film are oxidized to X. The electrons released from this oxidation reduce the Ag+to silver metal in the surrounding AgX crystal. X -+ hυ X¥ + e-(1a) Ag+ + e-Ag (1b) 2.

- These crystals are scattered in a gelatin substrate providing a buffered environment as well as stabilizing some chemical reactions. A cozy place of sorts. Light sensitive Silver Halides used in film photography are mostly based on Chlorine [Cl] and Bromide [Br]. Silver Bromide [AgBr] being used often, this is the one we will use our examples.

- A conduction-band electron can then go on to combine with a positive hole in the silver-halide lattice and form a single atom of silver. This single atom of silver is unstable. However, if enough photoelectrons are present at the same time in the crystal lattice, they may combine with enough positive holes to form a stable latent-image site.

- Color printers work the same way, except the above process is repeated four times. Four types of toner are used: cyan (bluish), magenta (reddish), yellow, and black. By combining tiny dots of these four colors, nearly every other color can be created. A photocopier works according to the same basic principle, except the electrostatic

- Collodion: This substance transformed photography. This a viscous mixture of gun cotton that is dissolved in alcohol that then creates a thin film. It is then mixed with silver bromide, silver iodide or silver chloride. This substance reduced exposure time to seconds instead of hours.
