Thanks drg Right now I'm just doing enlarging. I have a contact printer but, I already know the negatives I want to work with so have no plans for that in the next couple of sessions. I'll have to try the shower trick before printing to see if that helps. The heating is baseboard and the bathroom is tile floor. I also have an overhead exhaust fan that I run. I really made no effort to take care of dust this first attempt, so I'm hoping next time, when I'm more conscious of it, that it won't be as bad I'll go out this weekend though and pick up some canned air, a static brush, and scope out some filters.
