A full resolution sample photo taken with the 12-megapixel Canon EOS Rebel XSi at the lowest sensitivity, ISO 100. This image was shot RAW using the tungsten white balance preset and converted to a 16-bit TIFF with no adjustments, using Adobe Lightroom. The text, graybar, and logo were added in Photoshop and it was then converted to 8-bit and resaved as a maximum quality JPEG.
