My view: wet time to grain relation is inconclusive.(posted 8179 days ago)I have read several articles about this sort of issues, but none of them is convincing. Theoretical argument from either side is not too convincing and does not exclude the possibility of the other. Experimental arguments are based on too few data points to conclude anything meaningful (it just tells that the phenomenon is irrelevant for practical purposes).
I just don't want to sound like I support either side of this wet time - grain controversy. This is not because I don't want to sound controversial, but instead because I don't have any strong reason or urge to say this issue is a complete myth. I would like to have a good reason before I say something against widely held views (whether useful or not). I'm not brave enough to believe what Kodak states without any reasoning or data. (Did I say something like this before?)
My recommendation: Reasonable temperature selection and stability are important not to stress/damage the emulsion anyway. Wet time is much less critical with film than paper, but as a general statement, the shorter the less damage to the gelatine.
