Because of the speed of the film the fast and slow, and Fixatives on the amount of sodium thiosulfate join, high concentrations of fixative, fixing faster, if fixative of concentration above 45%, fixative is too strong, fotographic is not sensitive silver halide solubilies minimum, it reduces the cofficiency so that the inverse function of, say, fixing concentration is inappropriate, to weaken the effectiveness of fixative, at the same time fixing not 深透 and has a special interest.

由于胶片的不退影速率的迟慢，与不退影液洋的硫代硫酸钠参加度多少有干系，不退影液的淡度矮，不退影速率不离迟，如果不退影液的淡度超功45%，不退影液太淡之后，胶片未感光的卤化银凝固度最小，不正而贬低了凝固度，使得其不正的功用，所以说，不退影淡度把持得合适其时，不妨不收松不退影液的出力，同时不退影不不肤浅，并且有发黄的本体。
