I snapped this picture of a lamp in my office to test the speed of a Lexar UDMA 300x card with the Nikon D700, which is one of the few cameras that actually supports UDMA. The buffer definitely clears faster when shooting RAW.
I liked this shot because it reminds me of opening credits to Metropolis. Handheld, Nikon D700, ISO 200, Nikkor 180mm, f/2.8 @ 0.7s. Cropped and converted to Agfa Portriga Rapid tone in Lightroom 2.
