Skip,
Thanks for the drying ideas - the chamois leather wrap seems a good plan.
As for Photoflo - that's a bit serious. I use the stuff almost religiously
and have never had drying mark problems since I started using it. There is
also a lifetimes supply sitting in my darkroom! Does it affect the dev and
fixing stages if there are minute amounts of flo clinging to the plastic?
Cheers,
