Pushing Delta 3200 to 6400 or 12500 in Microphen?

[Stuggi]

Has anybody tried this? Ilfords tech sheets seem to indicate that it is indeed possible to do, but I can't really find any info online on what kind of quality you can expect from this combo, and what agitation scheme that should be used.

Delta is pushed already two stops if you use 3200ASA. I guess that very little of o photo remains if you push it further.

I pushed MF Delta 3200 with HC110 (which is certainly not the best dev for pushing high speed films) all the way up to 8000 and liked the results a lot. There are plenty of examples on flickr where Delta 3200 was pushed all the way up to 12800 and 25600 with high speed devs. You will not get results comparable to Delta 100 in broad daylight, but there is subject matter where Delta 3200 @ 12800/25600 looks great, especially dramatic night shots.

[Stuggi]

Yeah, I have both HC-110 and Rodinal from before, and I've never been quite satisfied with them for pushing, so that's why I'm thinking of testing Microphen when I saw that Ilford recommends it for pushing Delta 3200.

BTW, if Delta 3200 is already pushed 2 stops when shooting it at 3200ASA, what's the difference between it and Delta 400?

I think Delta 3200 actually has an ISO rating of 1000?

I guess Delta 3200 is also a fairly low contrast film, so it can be pushed to gain speed without the highlights blocking up so quickly.

Delta 400 pushed two stops would be pretty contrasty for the same subject matter.

Yeah, noticed that my quick ASA calculation was missing a stop (3200ASA - 2 stops = 800ASA and not 400ASA). That's what you get when you try to divide by 4 at 05:40 AM in the morning.

Funny thing, I just ran across this thread and the thread starter seems to have gotten usable results from pushing Tri-X all the way up to ISO 12800 with Rodinal. I have no idea whether this also works for Delta 3200, though, but I'm going to try this at some point.

I wouldn't push D3200 so much for 35mm, I tended to rate it much lower than 3200 anyway. But for larger formats, go nuts and let us see your results! I would *guess* that if you want to get 6400 out of it, you need to expose it for double time, i.e. meter as if it were 3200.

My guess is that the delta films simply won't push very well. I'd be inclined to go to hp5+ or neopan for this. The massive dev chart has times for neopan 1600 out to 12800.

No D3200 will push OK.As others have said it is designed to be pushed as it's true speed is probably about 1250 in a speed increasing developer. For dramatic night shots where no shadow detail would be expected then 6400 or even 12800 will be possible. Don't expect any shadow detail and don't go to these speeds unless acceptable shutter speeds cannot be achieved at a lower EI.

Delta 3200 is one of my favourite films - I rarely expose under 12.500 iso..
