Processing:
The experimental no.25 film can be processed in all types of processing equipment including spiral tanks, dishes/trays, rotary processors, deep tanks and automatic processors. This film is very robust. It can handle less than ideal processing conditions and will not contaminate the processing chemistry. This film must be loaded/handled in complete darkness due to panchromatic emulsion sensitivity to all the visible light spectrum. If processed in a development tank maually,, it is recommended to agitate the film for 5 seconds every 30 seconds of development. The development time must be decreased/increased by 15% each stop of pull/push processing of this film.
