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

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. -Aaron - This message is from the

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. Bill, KG4LOV [EMAIL PROTECTED] -

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 middle

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. I have heard that E-6 films have better

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
