From my various home dark-rooms the one thing I have to contribute is that it makes a world of difference in a makeshift dark room whether you are working at night or in the day. I can make my "darkish" room ok for prints in the day, and yet I must do negatives in the middle of the night. My life's goal is a door. Think closet. Who needs air? Anyhow, it works. Just think about giving up on light proofing everything and put the PM shifts in your Daytimer as Darkroom time.(posted 8787 days ago)Dean
