Saguaro Silhouette Sunset, photo by Harold Davis. View this photo larger.

The photograph of saguaro cacti silhouettes against the setting sun was taken from the roof of the Hopper house with a tripod-mounted camera at 400mm (600mm equivalent in 35mm terms). Tricky thing using a long lens with the setting sun, because you really don’t want to look through it when it is pointed right at the sun (it might damage your eyes).
