    Re: D 23 Users

    Tend to agree with Joe O'Hara that the differences between negatives - no matter what they're developed in - tend to be quite small. Maybe not indistinguishable, but small enough that focusing on one film, one developer, etc. and getting to know these seems a better course than getting lost in the weeds. And if that fits, then D23's simplicity is good enough for primary use and not bother with the rest.

    My thanks to Tin Can for this thread, for bringing out all the other users and how they use this simple stuff.

    The formula in the paper is correct. 1.5g/l phenidone.

    If it does, how does it handle rebottling, storage, transfer pump back and forth from 1 gallon tanks to 3 gallon tanks with a floating cover, which will add room air with every transfer

    as some here know I use a gas burst system with air compressor

    I can change to N2 and have worked with huge amounts of N2 as liquid and 5K bottles for decades, not film processing

    but we always run out of N2
    I have only used D-23 with N2.

    This is a good point, thanks Steve. The Kodak replenishment directions include both the amount of replenisher to be added after each square foot (or roll) of film processed and the maximum proportion of replenisher that can be added to the original developer. I posted the directions above.

    As an aside, I have been using replenished D19 in a (cine) reversal process, and notice that once I go past the total recommended proportion of replenisher (1:1 D19R to the original volume of D19) I need to change the processing times.

    I have always believed that the accumulated silver is responsible. This shows up when the negative is viewed by reflected light. I have never considered bromide as a factor.

This, I assume, is less than what it takes to turn it into D25. I will look up and post the directions later.
    Using DK-25R to replenish D-23 won’t turn it into D-25. The pH will be higher than that of D-25, and the pH is what differentiates D-25 from D-23.

    I've been developing xray film in D-23 at 1+3. Very pleased with the results. Not large format, but I love Ilford Pan F in D-23 1+3.

    At what speed do you rate Pan F in D-23 1:3? Thanks.
