Tim Tadder, one of the country’s hottest advertising photographers, has made a career of freezing all sorts of action in its tracks—like the billowing red hair of model Sarra Hansen in the photo shown here. Held aloft by a massive industrial fan on the floor behind her, her tresses flapped wildly, yet Tadder, based out of Encinitas, CA, still managed to capture every strand of hair tack-sharp.
