Response to one film/one developer

Joesph, I have always had different developintimes with the same film/developer combination for different sizes. Not only the difference between tray and tank development, which have substantially different agitation schemes, but also tank development of different sizes, i.e 35mm and 120. I suspect this is because of the difference in enlarging ratios, and fluid dymamics in different size tanks with different size film. Also, in order to reduce grain, 35mm film should be optimized for printing on grade 3 paper while 4x5 and 120 should be tailored for grade 2. I imagine you will have to test each one. As for the timer, clean the numbers and hope. If they still aren't bright enough, get some flourescent stickers and cut them up with scissors and apply them where needed (usually it is the moving hands that are the most important). Hope this helps, ;^D)
