I've no doubt HCB would have used digital. He hated the darkroom and never did his own printing after he could pay someone else to do it, and digital would have enabled him to shoot in lower light, with faster shutter speeds, maybe autofocus might have helped him do his work "only more so" in some cases.

Weston - somehow I doubt it but it's an academic question.
