First step is to wash away the silver halide crystals. It is made of a diethanolamine-sulfur dioxide complex, hydroquinone, sodium bisulfite, and potassium bromide mixed with water. in the stop bath you have to change the ph level to neutralize the chemical reaction, it is a form of acetic acid mixed with water. Then u wash off all the chemicals with water. During the fixer you remove the unexposed silver halide and leave behind the developed, exposed silver halide. Fixer consists of a salt of sodium thiosulfate mixed with water. The process of fixing ensures that the image on the negative is no longer sensitive to light. Then you finish off with a final water bath in which the film is rinsed.
