As you know, I'm still very new to this. I've just burnt and washed out my 4th screen but this time I've noticed a fair amount of the emulsion has come off. I used the same lamp at the same distance for the same amount of time as before, with the same emulsion and negative. The only differences where:
-I used a different sheet of glass (Maybe something about thickness stopping the
-It was left coated but unexposed in a dark cupboard for about a week as opposed to a day / day and a half max.
My gut feeling is that maybe the age stopped it burning quite so well but I can't think of anything to back that up. What do you think?
