One thing which has been the bane of my existence since the first roll of film I developed at home is the dreadedÂ drying marks. Those irritating little streaks on the base side of the film.
I’d tried everything. Lots of photoflo. Tiny amounts of it, just a drop. Squeegee/no squeegee. Sometimes I would be streak free and home clear, but more often than not, there they would be.
They do wipe off easily in my case. But I’d still prefer not to have to deal with them.
I don’t recall where I read this. Maybe FADU or APUG. But someone suggested distilled water for the final rinse, with just a drop of photo flo. I usually have that around anyway as I use it for mixing my stock solutions and diluted developer working solutions.
Whaddya know but it worked! Half a dozen rolls finished up this way, sitting in distilled plus a drop of the wash aid for a few minutes, and not a single drying mark among the lot of them! No squeegee either, which reduces the chances of damage. Win win, as they say.
So if you’re fighting this problem and are at a loss for how to fix it, this might just be the answer!
Next trick will be to see if I can get away with just plain distilled water and no photo flo at all. I’ll be sure to post how it goes.
