WikiAnswers contributors share their photographic knowledge:
- The standard temperature of photographic solutions (i.e., developer, stop bath, fixer, and rinse water) when processing film is 20 degrees Celsius/68 degrees Fahrenheit. Film and photochemical manufacturers normally provide an information sheet listing alternative time and temperature combinations for various developers and other photochemicals. Care must be taken not to use too high a processing temperature, as it may cause permanent damage to the negative ("reticulation").
- The temperature noted above applies to b&w film. The C41 process for color is 100F, which is more difficult to maintain throughout the process.
In addition, reticulation is caused by extreme changes in temperature, not merely processing too warm. It is difficult to cause reticulation in modern film. One last nit-pick: you don't develop negatives, you print them. You develop film.

What is the apparatus consisting of an optical projector used to create photographic prints from negatives?
Enlarger
Is film developing has to use fixer or only developer and stop can do the work?
You must use fixer. If you don't, the undeveloped silver halide will remain in the film, and you won't be able to get light through it--hence the negatives will be useless.
What is a Kodak projection paper holder model b pat?
Used in photographic printing. It's now known as an enlarging easel. It holds the photographic paper in place below an enlarger so that projected enlargements can be made from smaller negatives. Nora Hague Notman Photographic Archives
Is the temperature a rational number?
yes because there can be negatives
What element is used in photographic negatives?
Many are. But if you're referring to the main one used to form a stable image on the transparent backing, that would be silver.
