Many years ago, I lived in a small 1 bedroom apartment. There was a closet in the living room that was actually part of the overhang of the entrance stairway. For a full year, I was doing all of the B&W work for a local camera store in that space! I had an Omega D2 with coldlight head on a 3 foot deep shelf overhanging the stairs and 8X10 processing trays on metal storage shelves! THAT really sucked! At least when I processed film, I only had to be in there to load the tanks... I still can't believe how much work I did in that small space.
