This is by far my favorite tank used for developing film. I might even like it more than my Paterson! I’m a big fan of the size of this processing tank. The total solution it holds is 500 mL, this is great as Rodinal is a cheap developer. It takes about 20 mL of Rodinal and the rest is just water. I’m saving a good amount of money processing film at home, black and white film processing at a lab usually has pretty slow turnaround times and they often charge you additional since it’s not C41. I’ll be using this thing until it breaks, that’s for sure. The downside, which isn’t much of a downside at all is that it can only process 4 sheets of 4x5 film at once. Processing shouldn’t be rushed, so, I think 4 is enough to salvage any other sheets of film is need be. The tank will run you about $100 which is a good amount upfront but you’ll be able to save down the line if you continue to shoot and process film yourself. You can purchase the tank straight from Stearman, here.
