I’m more and more convinced that you could skip photography school altogether and just watch this ongoing series of videos of Gregory Heisler dissecting his photographs. Created by Profoto, the videos have Heisler explaining the creation of some of his most famous cover shots—none of which are more famous than the most recent video’s subject, the 2001 Time cover with Rudy Giuliani. A phenomenal and iconic photograph, to be sure. What’s most exciting about this shot, in terms of the lighting at least, is what Strobist David Hobby points out in his brief writeup: the lighting was environmentally centered. Heisler gelled his lights green and orange to match the warmth of the ambient city lights, and all of them were positioned below (except for the fill) to match the lighting that would be provided by the city below. A genius photograph, wonderfully executed and beautifully explained.
