- 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

- To understand the fundamental chemistry of silver-based photography, we must look at the photochemistry of silver salts. A typical photographic film contains tiny crystals of very slightly soluble silver halide salts such as silver bromide (AgBr) commonly referred to as "grains."

- A photograph is an image made by a photo-chemical reaction which records the impression of light on a surface coated with silver atoms. The reaction is possible due to the light-sensitive properties of silver halide crystals. Equation form for silver halides: Ag + + e – Ag. Species produced include: Ag2+, Ag2o, Ag3+, Ag3o, Ag4+, Ag4o In 1556, the alchemist Fabricius was …

- Chemical Reactions Involved in Photographic Processes A. Silver-based photographic processes. Capturing light to produce an image utilizes two properties of the silver cation: (1) Ag+ is reduced to silver metal in the presence of a halide which can be oxidized photochemically (i.e., a photon ejects an electron from the halide).

- appreciate the fact that a lot of chemistry goes into developing pictures. Does digital processing mark the end of chemistry in photography? There is actually plenty of fascinating chemistry going on—it’s just on a much smaller scale. Sensing light All cameras work by focusing light through lenses to create an image. A conven-

- BASIC PHOTOGRAPHIC PROCESSING CHEMISTRY. Acids, Bases and Salts are all used in photographic processing solutions. The oxides are used to make acids, bases and salts but are never used directly in photographic processing. Acids are used in stop bath and fixing solutions. Therefore, they have pH values less than 7. Bases are used in the developer.

- The film has four layers: The first layer is a protective coating which protects the emulsion layer that has the gelatin and the silver halide crystals in it. Higher speeds of film have multiple layers of emulsion. The third layer is the film base. The film base is …

- The size of the silver halide crystals has an effect on two things when taking a photo, the first of which is the film’s sensitivity. The larger the crystals, the less exposure to light that the film needs to render an image.

- 1. Exposure of the sensitive material, usually a gelatin emulsion of silver halides on a cellulose acetate film, in the camera. 2. Development in the darkroom by treating the film with a solution of organic reducing agents such as hydroquinone and N-methyl paraaminophenol.

- A silver-halide grain contains billions of silver-halide molecules, and it only takes two to four atoms of uncombined silver to form the latent-image site. In color film, this process happens separately for exposure to the red, green and blue portions of the reflected light.
