But it's so expensive. I still prefer Shoot Raw in Digital and PS it! I heard our teacher said, you can pull underexp (treat it in chemical longer or shorter to get the correction exposure) that's assume you know what is correct and aware of your mistake.
Thank Canon and NIKON bring SLR to consumer. Before that, shoot a landscape need 12 films. 3 bracket the exposure, 3 bracket the color temperature, 3 bracket for handshake, 3 bracket for your are just rich enough to afford the film.
