Wall of a trackside junkyard in San Francisco, whose owner is paranoid about photography. The guy thinks this is a rule he can have. Taken from the public street, so no, he can’t.
Shot with the Nikon D70s and the 18-70mm f/3.5-4.5 zoom at 35mm, ISO 400, f/10, shutter 1/250 sec. Cropping, white balance, exposure, contrast, levels, and highlights adjustments in Aperture.
