Times of transition, as seen in Brendon Purdy's Arcosanti, are potent times. It's no wonder that dawn and dusk are traditional times of prayer and devotion. Amid the grainy textures of cloud, land and people, the tiny point of the moon sets the cosmological context. Time-lapse photography has captured traces of the movements of the people, expanding our sense of time from "this moment" into "all moments." Based in Vancouver, British Columbia, Purdy travels widely and says his "greatest hope as a photographer is to capture something beneath the obvious, such as grace, nobility, humanity or wonder."
