Lightning from a red thunderstorm at sunset strikes the Arizona Sonoran Desert west of Tucson, AZ with saguaro cactus, cereus gicantica, silhouettes in the foreground. Original photograph taken with 35mm color slide film, Fujichrome Velvia ISO 50, with a Canon T-90 and a SSC 200mm f/2.8 lens at f/8, 30 sec. time. Fujichrome Velvia was manufactured to be sensitive to yellow and red light, so the color is what was faithfully recorded on film from shooting directly into the setting sun. Original slide was digitized by Kent Wood on a Epson 4870 scanner.
