But how does he turn up subjects? "To find opossums, owls, or any of the many creatures that come out at night, I use a bright Petzl Tikka XP LED headlamp"($50, street), says Crane. "On quiet night hikes, I scan with its beam, searching for two telltale flashes of light -- reflections cast by the eyes of even the most secretive subjects. If the light scares an animal away, I turn it off and stand quietly for a few minutes. Soon, my subject will return to its routine, and I can get my shot."
