They say that amateurs worry about equipment, professionals worry about time, and masters worry about light. Every photographer has experienced it: a moment when the quality of light changes--in a room, through the trees, on the water--and the ordinary is suddenly transformed into the extraordinary. What to photograph no longer becomes a question, as if God had reached down and pointed a finger, saying here, you will record this. In conjunction with ApartmentTherapy.com, these artists present interpretations on light, both literal and figurative, exploring and paying tribute to photography's true medium. Light is to the photographer, after all, what clay is to the sculptor. The camera is just an instrument.
