delta 3200 in prescysol/pyrocat hd?

[audible]

hi, i've been using both prescysol and pyrocat hd according to peter hogan's instructions with good results (1:1:100, box speed, 10min30sec at 24 degrees)

my films are acros and hp5. i'm looking for a faster film though, for really dark conditions, and am considering delta 3200.

my question is, for my current development process, what sort of speed can i expect from delta 3200? i should do my own testing, but i'm hoping someone can give me a good starting point. should i set my EI to 1600? 2400? 3200?

thanks

I'm at the same point as your are with this film and developer, so I too am interested in the answers to your question. In the meantime I shall rate it at 1600 and develop in Prescysol.

I've cut and pasted this from a post I made in another thread that you can find(there was a url link here which no longer exists) 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.

I'm not sure that I see the point. If I rate it 2 stops slower than 1600, isn't that 400 ISO, which is what I rate Delta 400 at?

How bad does the film actually look rated at 3200?? Use the speed.

dave - I said one or two thirds stop (1/3 or 2/3) - so 1250 or 1000, more than 1 stop faster than your delta. And the point is for the look, the film looks totally different to delta 400.

Gary - at 3200, i got very thin negs with no shadow detail - not how I like a neg to be, but if thin shadowless negs are your bag, then more power to you.

I’ve tried Delta 3200@EI 1250 in Precsysol - semistand, 11 min@24C. It worked well for subjects with fairly high contrast.

However, nowadays I use Pyrocat and find that Leon’s recommendations work very well with an EI of 1000 or 1250.

If I want more speed I usually use Tmax 1+4.

I can't find it but back when the film first came out, Ilford published that the film's actual speed was 800. The same is true of TMZ. I always shoot it at 800 and get a full range neg with perfect shadow detail. However if you can live with a bit more contrast the film can easily go to 1600 and still look like a normal film. I am curious as well what happens with pyro with the film. I might test it out as well. So far in my tests DDX gives the finest grain if that is a concern.

 

[Brian Jeffery]

Well, acording to the Ilford fact sheet Delta 3200 has an ISO speed of 1000.

I find Pyrocat-HD and Delta 3200 a good combo at ei 1600 - an example attached with an example of the grain. What I find is that careful metering makes a lot of difference.

Times were 23 mins at 21 degrees C - constant agitation for first minute then 2 inversions every three minutes

thanks guys...

i seem to be doing ok with EIs a little faster than the "real" speeds with my other films, so i guess 1250 or 1600 is a good place to start.

thanks for the example pix too. the grain is interesting... very different from acros or hp5, but quite tight. well, will find some time to shoot a roll or two and see.

So you did, just checking to see if you were awake.

I've found that for Delta 3200 rated at ei1600 and Prescysol EF, my developing time comes to 16 minutes with partial stand (10 seconds every 3 minutes after constant agitation for the first minute) at 74 degrees F. For low to mid contrast scenes this produces a very satisfying range of tones. For high contrast situations, the shadows can get thin and I intend to test at ei. 1000 and less time in the developer.

I get decent results from Delta 3200 at 1600 developed in Clayton F76+.
I'd rate it at 1000 if I could, but with the slow lenses (my 50mm is F4.5) I use with my RZ67, even shooting at 1600 is sometimes a stretch.
