Re: Advice: Drying Large Sheet Film (20x24+)

I have much better luck avoiding puddle/drying marks by hanging large
film. The advantage of Photoflo is that it makes the water come off the
film in a "sheet" rather than leaving drops. Exactly like the no spot
dishwasher products. This only works if the water has an "escape"
route. If the film is left horizontal (on a screen) then photoflo does
very little or no good.

For 4x5 to 11x14 inch film I simply hang mine from one corner over my
sink using a simple plastic clothes pin.

Very large film (16x20 or larger) won't be held by a single pin. On
these large sizes I use two pins on the short side of the film. This
allows the water to "sheet" off of the large film, onto the lower short
end of the film, and then fall off.

If, 5 or 10 minutes after hanging, you touch the lower end of the
drying film with some paper towels most of the excess water will be
absorbed and your drying time will be reduced.

Hope that helps.
