    Tmax 100 with HC110 is mottled

    I developed two rolls of Tmax 100 in HC110 dilution B at 70 degrees and they came out mottled. Is that due to HC110 being 'high energy'?

    Thanks.....

    No, it's from something else.

    (And HC-110 is not higher energy than any other developer)

    How is it mottled ? Have you had good results with this combination before ?

    I agree with Don. You've got some other ghost in the machine. Any chance film was sticking together in processing?

    You didn't mention the film size. Was it 120?

    If your development times are short you may need to pre-wet to get more even results (or so I've been told) - with any developer, not just HC-110. If the mottling is very white/grey, it is likely that your film was touching itself and it didn't get fixed (or developed) properly. If the mottling is in area like the sky, where you have a large even area of the same tonal value, then it is possible that there was too much fluid in the can and not enough agitation happened.

    There are any number of reasons, but if you could attach a thumbnail image it would help narrow it down.

    It was 35mm film. I presoaked for two minutes with agitation to eliminate the purple dye. Agitated 30 - 60 seconds (don't remember), then for 10 seconds every minute (gently), then used a water stop bath. Fixed for 5 minutes in Ilford non-hardening fixer. Looks more like grain. Never mind the composition/exposure...it was just an experiment.

    Thanks...

    The almost looks like reticulation. What was the temperature of the pre-wet, water stop, fixer, and wash?

    I think Matt has got it. If the temp varies too much between chemicals, the emulsion can crack causing reticulation, which looks like what you have here.

    Temp was 70, to start. It may have gradually dropped for each step after that. The final wash was 68
