Where are photographs developed?

Answer 1

You are not clear on whether you mean negatives, slides or prints; manually or by machine; color or black and white. The answer could be a long, long one if it is to be meaningful as there are many steps, controls and apparatus involved. Please Google it or borrow books from the library to appreciate the depth of the subject.

Answer 2

When you take a picture, light hits the film from the thing you are taking a picture of because everything reflects light. When the light hits the film, the film uses that light to take a picture. When you develop it, it is a negative (if it was black and white film, the people would be black and a White House would be black but a black shoe would be white) and you make it so all the white is black and all the black it white. When you make the picture, you use a sheet of paper that is not sensative to the red end of the visible light spectrum. So you use the enlarger to make a bigger picture onto the paper and when you run it through the cemical, it does the same thing as it does to film. Only that you aren't trying to turn in negative. The developer makes the picture darker so you can see, stop bath is used to stop the developer from making the picture any darker, and fixer makes it so the paper can be taken into regular light. Hope this helps. ************

Simply explained and applicable to B&W but not colour Photography, for sure. However, paper does not develop exactly the same as film. Paper develops according to how much light energy it received and no more. If properly exposed, you don't need a stop bath (acid) to arrest development, in which case it's primary function is to off-set the alkalinity of the developer, thereby making the fixer (acidic) last longer. Mild over-exposure can be arrested with the stop bath as suggested. Severe needing fast movement into the stop bath? Start over with the proper exposure! The purpose of the fixer is to remove undeveloped silver halide from the paper (otherwise you could not take it out into normal light) and promote stability of the image. Film fixer should not be used on paper (most contain a hardener) and don't have the proper characteristics anyway. Using a paper that is "not sensitive to the red end..." is almost always true. However, you can use panchromatic paper (sensitive to all light wavelengths, thus must be exposed in darkness) to make B&W prints from colour neg's.

Answer 3

Early photographs were developed using the cyanotype process. It involves using glass plates to hold the image still and to keep the image while it was developing.

Answer 4

In a darkroom or developing machine.
