I want to start processing sheet film in a Beseler 8x10 drum. I remember when I did the old EP2 process, it required 1 1/2 ounces of chemistry for the drum. What's the required amount of chemistry for 8x10 BW film processing? Also, what time adjustment I have to consider when the film is constantly being agitated? Which is better, one direction or back and forth? Any input will be appreciated.
