I appreciate there is no substitute for doing testing for ones own working environment and I intend to do that.
For a starting point, I have collected data for the following films which I was going to use as a starting point for what I consider to be a normal scene, (No + or - development)
These will be 4x5 sheet film, developed in PyroCat HD (1+1+100) (20°C) in a Paterson tank with gentle inversions every minute for 15 seconds.
Has anyone used any of the following films with tank inversion as above, and how close are the times listed below to what you have experienced.
