    Improperly Mixed Developer?

    Help! I am at my wits end. I have mixed and remixed this developer, and I get entirely random results ( as far as this defect is concerned). I will attach a sample to this post that contains the defect and another image of the blank end of the roll that shows the defect as well (its more accentuated where there is less silver density). My guess is that there are particles that were not mixed properly that cause extra development on parts of the negative. I am wondering if this is due to any other cause? This is Beutler, a fairly simple developer, with Tri-x 400 pushed to 800. I am making the developer dance a bit (my dilution is A3 + B1 + 20 water) for about 22 minutes. I have some developments where this spotting happens, and some where the film is perfectly normal. What is going on? How can i make sure my developer is properly mixed? I am mixing at the correct temperature, adding metol before sodium sulfite, and the sodium carbonate is entirely alone in the water. How am I messing this up? Thank you to all who respond.

    I have used this developer before a few years ago without any problems. That is why I am suspicious it may not be the mixing.

    Contrast has been heightened to accentuate problem easily visible when printing in the darkroom for any frame that contains it.

    I don't know hwat you mean by A3 and B1. Do you mean 3 parts A and 1 part B? The recommended dilution for the Beutler developer is 1 part A, 1 part B, and 8 parts water. If you deviate from this you will not get good results. There was a similar thread where the OP used this developer with added dilution as a stand developer with bad results. For optimal negatives this is a developer that is rather unforgiving as to exposure, diution, temperature, etc.

    What on earth are you talking about? Have you tried a standard ready mixed developer?

    looks like over development with lots of air belles. You need to agitate, tap the sides of the tank to knock out bubbles, and develop for less time or at a lower temp.

    I don't use this developer so I have no experience with it at all.

    I can say that this problem reminds me of severe foam during development, but that is a reach.

    Sorry. I have no real clue.

    Years ago when I was a "starving student" the Beutler formula was my developer of choice since it was dirt cheap. The results with Kodak Pan-X were stunning in their detail. But as I said your exposure must be spot on. Willi Beutler in his book stressed that one should strive for the thinnest possible negative with good shadow detail. So meter carefully and bracket when in doubt. Most films show an increase in speed so your EI will be different from box speed. Some testing in in order. Over exposure and/or over development and improper agitation will negate the purpose of this developer. So use this developer as it was intended and don't try to "improve" on it with changes.

    Best results are with slow traditional films ISO 100 or less. It's rather pointless to use this developer with fast films like Tri-X since the developer was designed for slow films. Grain will be accentuated. With Tri-X might I suggest D-23 diluted 1+1 would be a better shoice unless you really like grain.

    Avoid camera vibration. Best detail will be with a range finder used with a tripod.

    I worked only a couple of times with the developer. I can not say I have experience with it.
    First, I think it is good to consider that recommendation developer use only film sensitivity below 200 ASA.
    By changing the ratio A / B / water, have changed (decreased) concentration of Sodium Carbonate in developer.
    Perhaps you have a reason for changing the ratio A / B / water.
    Before You can try using a bath of sodium carbonate 5 g / l for a few minutes.
    Then wash thoroughly and then films them make your developer.
    You may to get rid of the problem.

    I wonder what stop bath the OP uses. Could these spots be the location where Sodium Carbonate rapidly released CO2? Are these spots Silver or actual damage to the emulsion?
    Trying to be the best of whatever I am, even if what I am is no good.

    I haven't used this specific developer, but the effect reminded me of a film that had been used from the freezer too quickly and had a bit of condensation on it.

    If you think the problem is related to particles of something undissolved then filter the solutions before use, in fact that is a sensible precaution anyway and something I do every time with developers made from a powder.
