Past Saturday, when I went for a walk on the Koeheide near Bertem, I took my Yashica Mat too. It was loaded with very expired Kodak 7Max 320 film. Nevertheless I exposed it at box speed and developed it for 75 minutes in 1:30 diluted Kodak Tmax developer. During the first minute I moved the tank around and then I left it standing there for the next 74 minutes.
It came out very well I must say and in de next few days I’ll post a few more from the same roll.
Like all my medium-format film I scanned it with the Epson V700 and Silverfast SE8.
