    Tetenal kit, one shot?

    I've decided to give C-41 processing a go. I ordered a Tetenal kit that makes 1 liter of developer, blix, and stabilizer, which is exactly the amount my tank takes. I've tried to search as to whether I can reuse these chemicals for more than 1 batch, but can't come up with anything definitive. If I could get 2 batches out of each kit, I'd feel good. It just seems a little bit pricey for 1 shot, but I'll continue anyway.

    Any advice?

    You can do two rounds no problem. I increase dev time by 15 sec for the second round.

    Much, much more than 1 shot. I reuse the Tetenal chemicals for a minimum 15 rolls, but a lot of mine are short rolls. The chemicals can last a VERY long time. This Summer I had a kit last well over 30 rolls, with minimal time increases. the tradeoff is increased grain.
    In life you only get one great dog, one great car, and one great woman. Pet the dog. Drive the car. Make love to the woman. Don't mix them up.

    I should add that "1 round" for me = 2x120 or 1x220 roll. So I usually get 4 x 120 rolls done for every 250 ml of the Tetenal 3-bath. Since I get the 1L kit, I can get 16 rolls of 120 done, which works out to around $1.05 per roll of 120

    Good to know. I will be using a holder that takes 6 sheets of 4x5 that fits in a Paterson 3 reel tank. How many rounds would you say I could get out of a liter?

    FYI, here is the insert I mentioned. I just ordered one, and hope it makes my 4x5 developing much more hassle free.

    My 1 round (2 x 120 or 1 x 220) is about the same as 6 sheets of 4x5.

    Very roughly speaking, a 120 film (6 cm x 83 cm) = 498 cm^2 times 2 = 996 cm^2, 4x5 film (10 cm x 12.5 cm) = 125 cm^2 times 6 = 750 cm^2, so 6 sheets of 4x5 is actually 25% less film area than what I consider 1 round's worth. I'd say you can do 2 rounds (12 sheets), if not 3 rounds (18 sheets) easy. Increase dev time by 15 sec for each additional round.
