Replenishment (photography)
Encyclopedia
Replenishment is used in photographic film
and paper processing, where fresh chemistry is used to replace exhausted chemistry in a continuous or per-batch fashion. Replenishment rates are calculated by the quantity of film processed in each individual bath; and additionally in Process E6
by the amount of film push-processed; and by film type in Process C41
(color negative) developing.
color developer exhaustion volumes vary according to the speed and contrast of the films. Please see Table 3-2 in chapter 3 of the Kodak Process C-41 Processing Manual Z-131 to see the different color developer exhaustion rates for the various Kodak color negative films.
