Ilford Delta 3200 in Pyrocat-HD?

[colrehogan]

Has anyone ever developed 120 sized Ilford Delta 3200 in Pyrocat-HD? If so, what conditions/time did you use?

yes i have indeed - and it was gorgeous! I rated the film at 1600, but in hindsight, I think next time I'll go for 1 or 2 thirds stop slower ... I used 1:1:100 at 21 degrees for 23 mins using 1 min constant inversions then 4 inversions every 3 mins. Here is a print scan from a 35mm roll I used with this, sorry dont have any scans for my 120 shots. Even with 35 mm, this combination is remarkably small, tight, crisp grain. IN 120 it's very nice indeed and the highlight tones are nice and bright - sort of reminiscent of older films.

hope that helps

I should have added that I rated the film at 3200. Thanks Leon. I do have a question, what is the advantage to making inversions every 3 minutes as opposed to making them every 1 minute?

from sandy kings article at Dead Link Removed

Minimal agitation has three desirable results: 1) it gives great apparent sharpness through the formation of maximum adjacency effects, 2) it provides a compensating effect, and 3) it provides increased emulsion speed.

we use this combo with great success. Started with Leon's suggested times and tweaked a bit from there.

Is anyone doing 1:1:200? My notes show delta 3200 rated @1600 1:1:200 70degrees for 30 minutes with 30 seconds agitation at beginning and in the middle (15 minutes).

I've got another test roll so maybe I'll try 1:1:100 and compare.

Thanks,

Will

I don't think Delta 3200 and Pyrocat are a particularly good combination. I use straight Xtol at 8.5 min in a Jobo and get a much better tonal range.

Decided to follow Leon's advice for 35mm Delta 3200 (EI 1600) in pyrocat and described in the quote above. Followed it exactly except I use sodium carbonate rather than potassium so used ratio of 1+5+94 using total quantities of 3ml A, 15ml B and 282 ml water.

Results are really good - there is grain as expected but it is really nice tight grain and the tonality is extremely good.

I attach a couple of scans - one of a picture (scanned neg) using this combo and one a detail from the scan (neg again) to show the grain pattern in detail.

I used spot metering placing the face on zone VI.

Bascially I think this is a really good combination and will be using again and also will try in 120 format. Thanks Leon and others on this thread. Also, you might be interested I reported back on another recent thread about pyrocat and efke 100 in 120 format.
