Pushing Neopan 1600 to 3200 - souping suggestions

I also asked this on rangefinderforum but the more input the better.

I was in Baltimore recently and shot a couple of rolls of Fuji Neopan 1600 @ 3200 using my Bessa. I realize many estimate the actual speed at between 640 and 800 but . . .

The lighting was flat (a bar).

I have four developer choices:

- D-76
- Rodinal
- Diafine
- HC-110

Of these four are any going to be useful for these shots?

If so, can anyone suggest some good dilution, time and agitations schemes?

If none of these will work, what would you suggest?

Thanks!

I use this film a reasonable amount of the time. I only (generally) use D76 and for push processing you should use it neat, which means no dilution, just use stock solution.

I use a diffused enlarger which is a soft light source, so I develop my negs a little bit more than you would for a condensor enlarger.

I rate the film as very good at 800, which I believe it works best at. At 1600 you are starting to get into dangerous territory, but it still works well.

For 3200 ASA, I use stock D76 for 17 minutes @ 20°C.

With this combination I have workable negatives and get quite good prints. As your lighting situation is flat, I'm assuming you had fluorescent lighting, this may be a reasonable way to go.

I'm surprised you had to push that far. I find that under fluorescent lights with film rated at 400 ASA, I can shoot at 1/30 @ f/2.8. Moving up the scale to film rated at 3200 allows some quite fast shutter speeds, or stopping down a fair bit.

Cache AB55? There was a posting here a couple of months ago of Fuji 1600 in this developer and it was stunning. I think he was shooting EI 1600.

hallo

i think emofin should also work good.
some guys swear on it
