Canon PowerShot S95
Below
is a comparison of Canon S95 images JPEG+RAW mode. The bottom image is
direct from the camera, downsized 12.5 %. The upper image is converted
with DCRAW, downsized 12.5 %. Look at the details in the edges and
corners of the image. The DCRAW converted image has noticibly more
visible area. The corners show very bad lens abberations, but it was
interesting to me that the viewable area is that much different.
