for fourmats
I developed some film last night- another roll of 6×7 and another 35mm one. Then I also grabbed an exposed roll of Ilford HP5 that I ran through a 6×6 Yashicamat last summer, and another roll of 35mm film which was almost a year old (T-max) and I had forgotten that it was half-frame. In other words, I developed 4 formats shot on 3 different types of film with HC110 (20C) for 10 minutes. All that stuff about exactness in development of film are just guidelines I think.
