I arrived mid-morning at began shooting overall and detail photographs of the rear and south sides of the building as the sun moved slowly across the sky toward the front of the athletic center. As the sun began to set late in the day I set up my camera for the hero shot. With the camera facing southeast I framed the photo to show the main entrance and the steel clad front of the building receding off to camera right. A few short minutes after the sun dropped below the horizon the southwestern sky began to glow and was reflected beautifully across the front of the building by the steel siding. I did a bracketed set of exposures as the light levels dropped, and then called it a day. A very good day!
