Delta 3200 @ 6400 in Rodinal, stand development?

[dyao]

Anybody ever try this before? I think the idea would be to develop to the point of exhaustion, like Diafine would (except I don't have Diafine).

I'm not concerned about grain. I'm thinking, Rodinal 1:100, for 2 hours, with a few inversions at the hour mark.

If you have, any tips? What would you recommend as the minimum amount of Rodinal per roll - 3 mL? 5 mL?

Thanks!

I'd say you are in the right ballpark there. Many say temp. doesn't matter with Rodinal stand development, but I'd keep it to 20C if possible. Don't neglect the inversions - I'd even do one inversion every 30 minutes.

Have you got a spare roll to do a test with?

I haven't done this with Delta 3200 but with Tri-X my experience has been quite usable at 90 minutes of development but little actual increase in density at 2 hours, only a build up of base fog. This with Rodinal 1:100 @ 72 degrees.

I agitate for the first minute and then one gentle inversion at 30 minutes and another at 60 minutes. This gets me an acceptable half stop beyond ISO 3200 (5000 maybe??), not quite 6400 though.

It would be interesting to test this film at both 90 & 120 minutes if only to determine the highest practical (usable) ISO in a push situation and whether or not it wants to fog and at what point the fog becomes an issue.

Otherwise, my usual stand process is one minute of agitation and then hands off for the next 59 minutes, again, 1:100 @ 68 - 72 degrees F.

Surely you mean an acceptable half stop beyond EI:3200, not ISO 3200. Because the last time I checked TRI-X was registered as a 400 ISO.

I have always heard about people pushing TRI-X to EI:5000 an on, but myself have never seen anything that wet printed very well. Scanning was a different story.

I have always imagined that usable results at EI:5000&beyond as wild rumours/urban myths - the kind of prints that everyone talks about, but are rarely witnessed hanging on gallery walls.

that potentially might be a nice wet print since the weird mushy "blacks" will not be weird and mushy in a wet print (i think- with my very very limited experience).
I always liked grain but somehow it is very very difficult to get it nicely scanned.

No pedantry in my thread please, thanks!
