    Who's knocking it? I'm all for it. I just asking questions because I want to know that it's going to do what I think it's going to do. And it seems that it is.

    I'm using a Jobo with a 3010 drum, 10 5x4 sheets at a time. If I read the Kodak documentation correctly, a liter is good for 10 10x8 sheets, so it should be good for 40 5x4 sheets. That's 4 runs at 250ml per run. If that's true, then what more could a LF c-41 photographer want?

    The only thing I have to be sure of is hitting the temperature on the nail head. My CPP-2 seems to be off about 0.7C (a displayed value of 20C seems to be in reality 20.7C).

    What is the visual effect of being a little high or a little low in temperature? I'm thinking too high a temp would shift colors toward blue maybe, while too low a temp would shift colors toward yellow? I'll need a densitometer and test strips to be sure no doubt.

    Bruce, I will not hazard a guess as to the capacity of the developer for sheet film. You see, you can process the equivalent of more than 2 rolls of 35mm in a tank at one time and this implies that the time must be adjusted in the very first process. This is why I do smaller batches of sheet films and use the Jobo recommendations. I do 8 sheets in one run using a 2000 series tank and the normal amount of developer for that tank.

    Over development makes the negative more yellow and underdevelopment makes it more blue. This is true of time and temp, but they also influence fog and contrast. That is a generalization.

    Keith, I was referring to c41 chemicals. And I've been in the store plenty of times. I'm not sure the last time you've bought a kodak 5L e-6 kit but they don't carry those either. That's only based on calling and speaking with the people in the back and searching the shelves myself.

    What c-41 kit? If there is a kodak c-41 kit, what's the product number? The only way I can get c-41 chemicals (no kits) through Samy's is a special order and that requires I buy a lot including 16 bottles of final rinse! That's coming from Juan in Pasadena last week. I've yet to get details about the remaining chemicals but it's going to be $$$$$. I don't shoot that much color neg so this all may not be worth it.

    Bill;

    Then try the Formulary kit, which is a repackaged Kodak kit.

    I will check the shelf this evening at Samy's Pasadena for Kodak C-41 Flexicolor chemistry. Perhaps they are out of final rinse, but developer, bleach, and fixer were there last week. It is a 10 L developer kit, which is easily sectioned up. (I mix 2 L at a time.) I have never purchased an entire C-41 "kit" from Kodak, so I do not know if they exist. Just a three-part developer kit, and separate bleach, fixer, and final rinse (previously called stabilizer).

    The last time I bought Kodak E-6 off the shelf at Freestyle was perhaps 3 or 4 months ago, and I ordered two kits from Samy's once ($109 after tax). I always got my Kodak C-41 at Samy's (most recently, Pasadena, and Fairfax before that).

    Buying 16 bottles of final rinse is really not all too expensive, and the stuff only lasts 8 weeks once mixed, so you will eventually use it.

    If you don't shoot much color neg, home processing is probably not worth the mild savings you will get doing small quantities. The real economy comes with a high volume of use. I get at least 40 rolls and/or 80 4x5 sheets (almost always a mix) out of every gallon of C-41 chems that I mix up, or else I don't bother doing it.

    If you need a gallon kit just to get you through a specific project, let me know. I have about a dozen that I stockpiled on hearing of their discontinuance. I also have plenty of the old stabilizer, if you are using older films that require it.

    Several people are still raising issues about the capacity of the developer. I posted this information on page 4 of this thread in post #39 for you all. This is an official Kodak document. The process there does not take into account the RA bleach and fix used today in minilabs so the process I posted is more nearly like the home process and should be used.

    Kodak makes a 5-Gallon -19 liter C-41 Developer Replenisher Kit which you can buy for $33. 19 liters of replenisher will make ~22 liters of working tank solution. 22L of tank solution will process, as PE pointed out above, 220 sheets of 4x5 (~ 15 centsUS/sheet) or 66 rolls of 120 (~50 centsUS/roll).

    Does anyone know if this kit is slated to be discontinued? I hit the panic button yesterday and purchased one so I now have two unopened kits.

    Post #39: Well, it is probably 5 rolls per liter of 35mm without time adjustment

    Post #36: you can do 10 rolls of 35mm / 20 exposure per half liter (pint or 473 ml actually) reading from a real C41 kit instruction. This is provided you adjust time properly upwards for every roll.

    So, there must be someone misunderstanding the "rules" somewhere. Personally, I would only do 10 rolls or less per liter myself just for quality concerns, but Kodak says 20 rolls per liter with time adjustments.
    ------------------------------------------------------------------------------------------------------
    I know I was confused. I didn't realize that Post #36 was reusing it. I thought that was not the preferred method. Then post #39, back to a smaller number. Of course, that is with 1 time use.

    Bottom line: So, with no reuse, which is the way I have always used it the past, it may be 5 rolls. If one reuses and adjust the time, its 10 rolls.

    I think I got it now. Whew, that was harder than the developing will be, Its doable for me and I will be ordering some. Maybe reuse will be acceptable.

    Thank you PE, for you help in this.

    Reread my two posts.

    It is 16 rolls of 35mm 20 exp per liter in the second post. In the earlier post I refer to a less conservative publication and changed my reference to a more conservative reference. The earlier post used a Kodak document which said 20 rolls per liter. I do not recommend this higher value. And note that the figures refer to use of 1 pint of developer.

    I myself am more conservative. I suggest about 8 rolls to 14 or 16 rolls / liter. And, IMHO at 14 or 16 rolls, I believe that there will be a small sacrifice in quality. I have never pushed it that far though, due to my conservative nature in these matters.

    The figures are from an official C41 dataguide by Kodak and still hold true for the developer in any case.
