When you say you "snap the film" to get rid of water, I get worried.(posted 8741 days ago)The purpose of LFN and Photoflo is to reduce surface tension, that is to get the water to sheet off instead of form drops. Better to have a throughly wet surface and have it all flow to the bottom, than drops form, which may dry in place, leaving marks.
1. Use distilled water for your Photoflo/LFN solution. 2. Don't snap the film, let it all run off. 3. If you have the film horizontal rather than vertical, the water flow has a shorter distance to the bottom of the film, so it does it faster, and dries faster.
If you get an accumulation of water at the edge of the film, you can run a small towel ON THE EDGE ONLY to reduce its accumulation. You may have to do this several times. I do this with sheet film, but only at the corner, as I hang it by one corner.
