hi guys,
I’ve been processing color 4x5 negatives in a SP-445 tank. Has anyone used theirs for stand development? I read that it’s about 1-2ml of Rodinal for each sheet of 4x5 film- the tank holds 450-480ml of liquid. Would I just mix 1-2ml per sheet in 450ml of water?
Typical ratio for stand development is 1 part Rodinal to 100 parts of water for 1 hour. So 4.5 to 5 ml in your 480 ml would be about right. You don't have to be exact. The Rodinal is pretty much all done after 30 minutes anyway I don't know what the additional 30 minutes gets you.
