By the way, I do want to mention that you can, of course, use similar techniques to good effect for contemporary portraiture. Phil Borges often uses a single flash with umbrella to shoot his shaded subjects. (And a Hasselblad to allow flash synch with shutter speeds high enough to render the background correctly exposed.)(posted 8390 days ago)http://www.philborges.com/enduringspirit/esphoto13.html
