I have just started developing films again, having found a hoard of exposed material I didn't get round to processing whilst i was working. Might be fogged but there is only one way to find out. My problem is the water at this time of year (April) comes out of the mains tap at 13C. Does anyone have any experience of cold temperature developing? It's a pain having to heat it up to 20C which is what the tables provide information on. I am using HC110.
