The UPS Store
This building is on the corner down the street from my office, and I drive past it every day as I go to and from work. I've been waiting months for some decent clouds to show up at the right time of day so I could take a picture of it.
Technical information: Shot with a Nikon D40 and Nikkor 35mm f/1.8 DX lens, aperture f/11, shutter 1/500 sec, ISO 200. Lens correction for barrel distortion, curves, dodging and burning applied in Photoshop CS5.
Thoughts for improvement: The big mass of clouds at the right could have a bit more texture. It would also be good to try shooting around sunset, when the light is warmer.
