Dumb Question On Exposure

[marke]

Amy, I shoot a lot of Arista Preimium 400, usually exposing it @ EI 200. You'll have to experiment with your own camera and see how it meters.

Thanks Wolves... some info I've learned already in the course of this thread, but you explained it all quite well and easy to understand.

Glad to have helped! Try this exercise on a digital, and think of grain as the film-equivalent to noise: Set your digital to 100 ISO take a shot, but under-expose it deliberately by 2 stops. Now re-take but set the ISO to 400 and expose at the same settings. Now go fiddle with the under-exposed shot in your favourite program and get the brightness/contrast etc as near as you can to the 400-ISO shot. It will be noisier, for sure, which with film would mean grainier.

Grain can be deliberate, for artistic effect, so under-exposure and push-processing is one way to get it. Often it's simply the case that there is no film sensitive enough for what you want, or you don't have it available, so you suffer the grain in order to get something rather than nothing.

Thanks again Wolves... your info is very helpful!

Mark... sorry if this is a dumb questions, but what does this mean - "I shoot a lot of Arista Preimium 400, usually exposing it @ EI 200." Do you mean when you're shooting, or when you're developing?

Also, do you find the AP400 similar to Tri-X like I've heard from others?
