He was personally selected by Adams to be the exclusive printer of the Yosemite Special Edition Photographs in 1975, an assignment Alan continues to this day, making each print by hand from Adams' original negatives using traditional darkroom techniques. Alan specializes in helping photographers at any level identify and better express their photographic vision and has led workshops in locations ranging from the scenic Southwest to the mountains of China. His photographs hang in collections and galleries around the world and have been featured in campaigns for companies like Boeing, Nike, IBM and the National Park Service.
