    Kodak Flexicolor LORR+LU mixing

    I read through the archive and I just want to make sure that I am doing the right thing. As I understand it, if I mix the Flexicolor Starter with the Dev/Repl, then I can use the mixture as one shot.

    The question is, for example, Unique Photos sell them as 5L Dev/Repl and 1.2 Starter. Do I use them in that ratio, and get 6.2L solution in the end, or do I mix them at different ratio?

    Please help. Thanks.

    Not sure what you mean by "one shot"; how you mix it has no bearing on whether you decide to reuse it. If you mean "mix on demand," I don't know. I guess the proportions would be the same. I would suggest mixing all 6+ liters at once though. Evidence (and my own experience) suggests that the working solution keeps better than the stock component chemicals. Plus, you get consistency between rolls (i.e. you can eliminate some variables if things go wrong).

    I store the working solution in a dozen or so 600ml bottles filled-to-capacity -- perfect for one roll of 120 or two of 35mm. My notes are at home, but the five liters of developer plus the starter yields just over six liters of working solution. The starter from Unique is more than you need, so store if for your next five liter developer purchase. The starter by itself seems to keep for a long time.

    Thanks for the info. My question really is, do I mix the 5L Dev/repl, with the entire 1.2L Starter.

    Sounds like it is. THANKS!

    No! Don't add the starter undiluted. Read the mixing instructions. I'll follow up with details later.

    IIRC, the Flexicolor Developer/Replenisher uses about 14ml of starter to make 1 liter of working solution developer. So doing the math the answer would be no, you have a lot more starter than you need. And you need to add water as well.

    Edit: I do not use the LORR so your starter amount be be different than mine, but any difference should be slight. See Ed's post below.

    I had posted a similar answer as RPC on LFPF. There should be instructions on the replenisher package, and if not, on Kodak's website somewhere.

    OK Thanks! I will buy the chemical now and sort out the proportion before they arrive :-)

    You want the Kodak CIS-49 document about mixing partial quantities. No need to mix the whole 5 liters at once. It'll only last a few weeks once mixed anyhow.

    You can also get away without the starter if you like. All the starter does is make the developer act like solution that's had a few rolls run through it for process stabilization and consistent results. If you are a home user you will likely never know the difference.

    Also make sure you seal up the bottle of Part C really well if you do not use all of it. You can also store it in a refrigerator to slow oxidation. Part C is the color developer and is the part that goes bad. If Part C should happen to go bad before you have used all of it, you can purchase CD-4 and make your own. The instructions are here somewhere. So if your Part C goes bad, do not throw out Parts A & B. Just make new C.

    The 5 liter developer/replenisher kit will require around 1.55 liters of starter (200ml of starter concentrate plus water to make 1550ml). This will yield about 6.5 liters of working strength developer. But you should do the math to convince yourself.

    Don't know if the picture helps. I've jotted down the amounts since I go "back to the bottle" with each 5L kit I buy.

    It absolutely will not! I speak from experience. I've kept the stuff over a year and have gotten printable negatives with density as good as freshly mixed.
