i feel like i can see stuff in my darkroom with the safelight off. this makes no sense to me. it is a cement room with a small window and a door. the door is caulked, weatherstripped, and whatever that rubber thing that goes across the bottom is called. two pieces of duct tape over the keyhole. the window is sealed from the inside with tinfoil and cardboard and from the outside with a vinyl board. during the day and with lights in the adjacent room turned on, there is not a pinhole of light to be seen. even after waiting 15 minutes in the dark. tonight i used it to change film for the first time. loading 4x5 holders. in addition to it being dark outside, i turned off the lights outside the darkroom. i cannot fathom how there could be any light getting into the room. still, i am almost 100 percent sure i can see my hand waving in front of my face. even if i close my eyes tight. is this my mind messing with me? i will find out when i develop later this week if am truly light tight, but i am curious if this is a common phenomenon? thanks!
