I am planning to develope some 9x12 cm sheet film taken with myc ICA folding camera. I suppose it will be a tray developement.
What do you people use to keep track of time in the dark. I had been planning on using a normal egg timer until it dawned on me that I will not be able to set it in the dark. Silly me. What do people use for this? I thought about discoupling the enlarger from the timer and set the timer for 5 minutes and just listen to when it stops and then hit it again. Better ideas? About timers, the timer I'm using has a "glow in the dark" dial. Is this film safe?
