Alleys can be magical places. Just think of Diagon Alley in the Harry Potter books. The Mission District of San Francisco has a number of alleys, made magical by the artists who have decorated them. Some of these artists have gone on to fame and fortune. Unfortunately, I have no idea who painted this garage door in Clarion Alley as I could not find a signature.
To make this image I shot five exposures with my camera on a tripod using manual exposure mode. Each exposure was exposed at 35mm, f/11 and ISO 200. My shutter speeds ranged between 1/10 of a second and 1/200 of a second. I combined the five exposures using Nik HDR Efex Pro.
