    I did a search on apug but nothing came up. Does anyone have some times they are willing to share. Yes I will do some testing but need some times to get started with.

    Thanks for you help.

    I would try 20-25 min. Agitate for 1 min., then 10s every 5 min. Pyrocat-HD (glycol) 1:1:100,20 deg C, shot at EI 400.

    Thanks but I'm looking for semi-stand times.

    10s every 5 minutes is not semi-stand?

    I used to use 13 minutes at the same dilution, agitating 10s every 3 minutes with TMY, Tri-X, and FP4+.
    If I used standing development, I agitated for the first minute, and then let it sit for 30 minutes, agitating once half way through.

    Well I guess everyone has a different idea of what semi-stand is. My apologies :smile: My idea of semi-stand is to agitate for 10 sec's at the beginning and then another 10 sec's at the half way point.

    I will give the previous ideas a try but still would like to know if anyone has some times for the way I normally do semi-stand.

    Thomas your "stand" development is very close to what I do. Looks promising. Thanks.

    Ya I know I'm a fussy old bugger.

    PLEASE let's not let this thread devolve into a discussion of what is or is not semi-stand etc.

    I think you're right calling that semi-stand Eric :D Stands 6 mins after all.

    I used to use 15 mins @ 20ยบ 1+1+100 with Tmax 100 & 4400 with normal inversion agitation, you'll only need 2 or 3 mins longer with 5 min gaps.

    I should have added that I expose the film at an EI of 250.

    It might be worth contacting Steve Sherman as he does a lot of work with Pyrocat-HD in semi-stand routines. Or maybe it is minimal agitation (which usually means more agitation than semi-stand). Not sure, but he might have some advice. I don't know what film he uses though.

    I found info in my notes from Sandy King for the following, some adjustments will need to be made for TMAX400 but at least it can give you a starting point:

    "Times for Tri-X should be very close to those for HP5+, but I have not tested this." SK

    HP5+ semi-stand:

    Pyrocat-HD of 1+1+150 for semi-stand. That is initial agitation for 1.5 minutes, and then once again for 10 seconds at the 1/2 point of total development time.

    HP5+
    high contrast scenes, 40 minutes
    normal contrast scenes, 50 minutes
    low contrast scenes, 65 minutes

    Again, I don't use either TMax or Tri-X but the adjustments I have made for Delta and FP4+ (1+1+100/1+1+150) at 64 have come out beautifully. I just personally prefer long dev times. It's a visual thing.

    Please post whatever results you end up with so we can all add it to our records.

    Don't forget to pre-soak
