Times for TMAX 400 in Pyrocat-HD , semi stand

[Eric Rose]

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.

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 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.

Good luck with it, Eric. Hope you get the negs you want.

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

I used to use 15 mins @ 20º 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.

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

How did it turn out, Eric?
