This discussion reminds me of some of my own experiments with Acufine in
the 70s. I remember getting some very nice results with the old Royal X
120 rated at 4800 and developed in Acufine. It allowed me to shoot
indoor basketball action at a 1/500 shutter speed with my old TLR
Mamiya. The prints

Bill, now I wonder what I have been getting when I request
push-processing. I often shoot NHGII 800 and Supra 800 at 2500
or 3200 with a two stop push (shooting indoors). Often the results are
nice, sometimes not. If I am not getting a two-stop push in the
processing, what am I getting?
Okay, so when I need 1600 or 3200 and have 800 in the bag, should my
strategy be to rate the film at 1600 or 3200, but have it developed
normally? This would save a couple of $$ on processing.
Yep.
Try it. Try some head to head, some pushed, some not.

OTOH, if all this is correct (and I assume it is), maybe I'll just try
Fuji's new ISO 1600 and shoot it at 1600.
I've heard, but not tried, that Fuji 800 underexposed one stop and processed
normally gives better results than 1600 shot and processed normally.

Yes ... but there is so much discussion in many fora that say Acufine,
and other developers, increase the speed of the film. I guess the only
way to test that would be to shoot a subject, like a wall, that has some
texture and some detail, measure the exposure off a grey card to find a

I don't want to stir things (well, maybe I do:), but in my experience,
T-max developer is almost the same as accufine. A hot soup: nothing
more, nothing less.

Push processing C-41 film does not work at all. Anyone who says
otherwise is fooling themselves. The C-41 process is a develop
to completion process, and any additional development merely
adds to the base density.
And yes, I have proven this.

Erm, well... der. Slaps an A-duh sticker on his forehead. So then why is
BW different than c-41? I've also pushed c41 with decent results (read-
grainy as hell), though not nearly as much as bw.

Well, duh, because it isn't C41 chemistry unless you use the chromogenics

Here's a much simpler way to understand it.
To pull a film is to overexpose it. When a film is overexposed, one
must decrease its development time, or underdevelop it, relative to
the standard development time.
Overexpose + Underdevelop = Pull
To push a film is to underexpose it. When a
