When & How to Replace Chemicals
Important: The chemistry’s condition is important for proper film processing. Exhausted and/or
contaminated chemistry will lead to poor images. Since the processor is used in the final stage of
generating an image, it is normally blamed for poor image quality, overlooking the chemistry.
Before assuming the poor image quality is due to a processor problem we highly recommend that
the chemistry be checked.
