Hello, I am fairly new to developing 120 roll film in a hands on basis. However the darkroom at school that I use has the equipment, chemicals neccessary. I believe they use something from Lauder apparently. The film is Ilford Delta 100. My question is for the chemical process are the chemicals used for 135 film going to be the same as for the 120 development? I.e. fixer, hypo, etc. Also what about the timing? More or less or perhaps about the same. Thank you.
