Rim light defines the outlines of a subject by illuminating its edges from behind. In this landscape shot of saguaros near the ghost town of Goldfield, I took advantage of a setting sun to create such light. The warm light also increases the color saturation within the image. The saguaro grows only in Arizona’s Sonoran Desert, Mexico, and a small part of California. Its blossom is the State Wildflower of Arizona. Saguaros can grow as high as 50 feet, and live as long as 150 years.
