Controlled sample photos taken with the Canon EF-S 10-22mm f/3.5-4.5 lens, mounted on an EOS Digital Rebel XTi digital SLR. All three photos were taken at the same exposure and focus settings and the camera was on a tripod. The images were captured in RAW mode and converted to max quality JPEGs with Adobe Lightroom Beta 4.0. They have not been adjusted at all.
