Hypo Photography
photography help!?
1. The chemical called "fixer" or "hypo" (A) removes unexposed silver halide crystals from black and white film (B) should never be reused (C) helps eliminate water spotting on developed film
2. When developing film, the temperature of the chemicals and water (A) is unimportant (B) should be kept at 68 degrees (C) depends on how many exposures are on the roll of film
1. Fixer removes undeveloped(not necessarily unexposed) silver halide crystals from the film. It's not totally correct to call it hypo, though, as hypo refers specifically to an aqueous solution of sodium thiosulfate. Most modern fixers consist of ammonium thiosulfate in acetic acid, which actually both much faster and much more effective than sodium thiosulfate fixer.
2. None of the choices are totally correct. Developer should always be held to a consistent and known temperature, although it doesn't necessarily have to be 68 degrees.
