Is there a big difference in times/dilutions for Technical Pan in 35mm compared to 120? or has the bottle of PMK I bought last summer expired(shoulda bought 1 batch, not 2...)? I'm using the same amount/time/dilutions/agitation for 1 roll of 120 as I used to for 2 rolls of 35mm (20oz), and my results are different, way different...(posted 8856 days ago)ps where's Gene C.? I haven't heard from him for a long time?
