Some photographers have built entire careers on pictures of doors and doorways, which seem persistently photogenic in a way that is odd for something so specific. I, in contrast, find that I seem to take an awful lot of pictures of stairs, and I have no explanation.

Shot with the Nikon D70s and the 18-70mm f/3.5-4.5 zoom at 70mm, ISO 400, f/11, shutter 1/60 sec. Exposure, contrast, and highlights adjustments in Aperture.
