The LDS Temple and reflecting pool in Salt Lake City, Utah. This was shot handheld with the Canon EOS-1D Mark IV digital SLR at ISO 6400. The RAW file was converted with Adobe Lightroom and adjusted a bit in Lightroom and Photoshop to bring out more shadow detail. No noise reduction was applied in post-processing, though. I've posted it at the original resolution for the pixel peepers. Click on the image to see at at 100%.
