One assignment we had this semester for the class Advanced Studio Lighting with Greg Blue was shutter drag. It took me the longest out of any to complete. I guess the concept didn't click (dark subject white background, duration light and strobe, long exposure, move the camera) even though it's relatively simple. Well I shot it this weekend. Here's my setup and two of the final images.
Nikon d90 w/85mm f1.4
P.S. more potato heads to come.
