    That's a good idea Jim. In my case it was probably was the wash water that was the temperature variable, everything else was just sitting in bottles in the room.

    In its most severe form, that temperature differential can cause emulsion to lift right off the backing. Quite a bit of the newsreel film of the Allied invasion of Normandy on June 6,1944 was ruined by an overenthusiastic lab tech who ran his developer bath too hot. Talk about no chance for a second take!

    Yikes, that's a big "ouch" for history!

    Interesting, this is the first time I'm seeing the fabled reticulation effect. Not because I'm some processing guru, I just have very little experience doing black and white. Anyway, I can see why some go for it. It looks like an aged painting.

    That looks exactly like the reticulation I got with Neopan 400. I found that film, or that batch of it, particularly prone to it. I think I blamed it on leaving my running water wash going and the water temperature changing drastically as usage in my apartment changed.
