ok, i haven't really delved into this yet but i'm chomping at the bit to do this. i just can't get away from those really beautiful shots that you see of those very gritty faces or hands...almost to an abstraction. LOVE IT!!!! i've shot a few things in the past with b/w film and very close, undifussed hard light (one light) and almost got what i was looking for. that was in college and with a canon fully manual, 35mm ef. now i'm using a 5d and a 24-105 with full studio strobes and soft boxes. i feel that i'm getting my gear together enough to go out and really try some of these shots (either in studio or not) and i'm really focusing on learning about the ISO and how this affects my shots. SO, the question is, is there a general rule of thumb to achive a grittier image with such combos as bracketing, ISO's, filters, etc? these are some that i'm referring to: http://photo.net/photodb/photo?photo_id=5815657 http://photo.net/photodb/photo?photo_id=6194413 http://photo.net/photodb/photo?photo_id=5987670 http://arthistory.about.com/od/from_exhibitions/ig/Annie-Leibovitz-at-the-DIA/Willie-Nelson.htm is this possible with the 5d?
