Just wondering who uses a water presoak, and of those who do, do you use tap or DI water? I always mix my solutions with DI water, my stop bath is running tap water, and I soak my film in DI water with Photoflo at the end. I've also been doing my presoak in DI water, but I was wondering if it would be ok to use tap water for this. I was worried that it may cause some ill effects in the developer, but there is such a small amount of it retained in the emulsion when it is transfered, that I'm not sure it would effect the large 500-1000mL developer. Any suggestions?
