I have been away from teaching basic black and white processing for a few years; working in the world of advanced and digital courses. As I get prepared to bet back to teaching basic this fall I am once again pondering whether I should start students with the T-grain based films or stick with good old Tri-X or HP5. I had not made the switch to t-grain in my classes last time around. Any suggestions/experiences from fellow instructors?(posted 8742 days ago)P.S. I still stick with the traditional emulsion films for my own work, and just processed a few roles of old T-Max I found laying around. Is the used developer/fix and washing agent supposed to be that purple or did that have to do with the age of the film?
