OK, you guys almost got me. I had a flashlight in my hand and was headed up to the darkroom to check, when I stopped on the stairs and thought "Is this something I really want to know?" Seriously, I'm obsessive enough about that sort of thing that I would feel compelled to do something about it if I did see dust, and who knows how much lost time and money that could lead to? No, much better to put the flashlight away, go out to the garage and grab a fresh Ale, then head back up to the darkroom for a printing session using my time-tested static brush and canned air. Ahhhhh, much better. Ignorance truly is bliss!
