Does a daylight tank for 5x7 exist? Or for that matter 8x10, though I suspect the answer to the latter is no. Did anybody ever make one? I am aware of the Jobo system and also of the use of unicolor drums, but was looking for a more traditional daylight tank. I am quite happy with my HP combi tank for 4x5 which gives me very even development. My only gripe is that it handles only six sheets at a time. Thanks. Sincerely, Hany.
