One of my favorite photographers is Philippe Halsman, the great portrait artist. He's taken several portraits that everyone has seen, like this shot of Einstein and this Audrey Hepburn. His most brilliant work involved asking his subjects to jump for him, then capturing them midair. Everyone from Marilyn Monroe, Grace Kelly, Dean Martin and Jerry Lewis to Salvador Dali, Richard Nixon, and the Duke and Duchess of Windsor complied. You can see a lot of these great shots here and here. For this Dali portrait, he had to suspend several props from wires, then have a perfectly timed bucket of water and three cats sail across the frame as Dali jumped.
