I'm interested in some fast film, so I was thinking about Ilford delta 3200 Film.

To what ASA does this film test? I'm thinking of the ASA needed to have a Zone I yield a density of 0.01 above film base plus fog. (I think I got that right.) By this test, most films test out to about half the mfg's recommended ASA.

Also, how does this film behave; what are people's experiences with this film. How well does it expand and contract?

Anything else you can tell me would be appreciated.
