I want to try developing Foma's R100 35mm film in their positive developing kit and have some questions. (1) How is the re-exposure done? The instructions say 30 seconds on each side of the film at a 1 meter distance from a 100 watt bulb. So do I just take the lid off the tank and hold it towards the light for 30 seconds and then turn the film reel over to do the opposite side? (2) There is no mention of agitation for each stage of the process. (3) I'd like to try some 120 films so has anyone successfully processed any other films as positives in this kit?
