Acquired a few rolls os MACO B&W "UP" films (100 & 400 ISO). I use TMAX for all my processing - only the ISO 400 has a dev time for TMAX - 8 minutes - a dash against the ISO 100 film. I will do a test run (say 6 or 7 mins) for the ISO 100 film. In the meantime, anyone got experience with the TMAX/ISO 100 combination. Thanks.(posted 8975 days ago)
