    Thanks. That would be around 20 - 25 120 films or 70 - 80 4x5" films - that sounds indeed like a lot. Is that realistic?

    LOL! 10-12 does not sound like much to you but 20-25 sounds like a lot! Picky picky! Figure 15-18 since that'd be your sweet spot and be safe! :-)

    1600 square inches is 20 120 rolls = 20 135-36 rolls = 20 8x10 sheets = 80 4x5 sheets

    I've been using TF5 which I mix with distiller water.

    Thank you. I would indeed stay on the safe side.

    One repeated question - does anybody has idea/opinion/experience with the alkaline fixer from Moersch I have mentioned before (page 8) ?

    I've been using TF-4 for years for my films. Great stuff! I do two one minute constant agitation rinses as a stop. After mixing up a gallon of working solution, I pour just enough for the format of film I'm working with: 250ml for 135 film and 400 ml for 120 in a 16oz steel tank. I fix three rolls and discard and use a fresh quantity from the gallon of working solution. I'm probably well off in not stretching the capacity but I feel better by not trying to economize by pushing my luck. Fixing is so important and since TF-4 is $10.99 a bottle at Freestyle it's worth knowing my negs should be stable for many years to come.
