There are two basic kinds of developers: film, and paper. You "develop" exposed film into a negative through a developer bath. Then you typically print the negative (either directly onto paper as a proof, or to an enlarged size - 4x6, 5x7, 8x10, etc. with an enlarger, by exposing the paper to light that is filtered through the negative, creating the positive that you then "develop" in a developer bath. Once the film and/or paper is developed, you then rise off the developer in a water bath and to stop any residual continuing development then put the film or paper into a "fixer" bath, and then water to eliminate the fixer, and then to dry.
Color film and paper require more complicated, but similar processes.
Old fashioned X-ray film is similar.
There are many different manufacturers and formulas, that can vary with the kinds of film and paper you use.

To the point of the question: developer acts chemically on the "latent" image that cannot be seen until the silver salts (silver halide crystals) sensitized by light are converted to black metallic silver. The developer can distinguish between crystals that were and were not exposed (sensitized) to light.

What does STTP do in a photographic film developing formula?
In the processing of photographic films, plates or papers, the photographic developer (or just developer) is a chemical that makes the latent image Latent_imageonthe film or print visible. It does this by reducing the silver halides that have been exposed to light to elemental silver in the gelatin matrix. As a generalisation, the longer a developer is allowed to work, the greater the degree of reduction of the silver halide crystals to silver and therefore the darker the image.

what is the chemical used for making photographic plate?
For photographic plates silver halides are used.
Helium is the gas used in photographic lamps?
Not helium. But xenon is used in photographic lamps
Is nickel used in developing photos?
No, not directly. There are processes where nickel is used in recovering silver from used developer. Also, some developer tanks are stainless steel (typically, steel with about 18% chromium), which are usually made of a higher grade of stainless steel that also contains about 8% nickel. Other than these remote possibilities, I know of no other use for nickel in the photographic process.

Ammonium Citrate in distilled water is an alternate developer for Platinum and Palladium photographic prints (Iron replacement by Pt and/or Pd). It is cooler in resulting print color than the usual developer - Potassium Oxalate. See www.bostick-sullivan.com
