Context: If you read my most recent post , you know I ' m building a darkroom . The first big challenge was to get a good color . If the darkroom were somewhere that I could just shut the door and no one would ever see it , I 'd just paint it black , like sensible photographers do . However , I ' m using the basement hallway that leads from the stairs to the game room and powder room .
