I shoot with a Canon 20D at the highest quality JPG setting. I don't use RAW files. I've been happy with the results produced with this camera and my lenses from using Photoshop CS2 and iPhoto 6. Certain lenses always seem to need a little extra help in the sharpening area. My 17-40L lens is excellent but I usually apply extra sharpening and there is some slight curvature of field at the edges. Likewise, with my Canon 10-22mm ultrawide lens the results are really good right out of the camera but always look better with a little extra sharpening and can certainly use some edge of field straightening. I can do this on an individual picture basis with Photoshop but it tends to get boring and time consuming.

When I first purchased DXO I had photographed a meeting with a variety of lenses but mostly 17-40L, 28-75 Tamron, 70-200MM f4 Canon lenses. I loaded the 300+ shots into DXO
and after selecting approximate distance of shot for each picture (Canon does not include this information in their EXIF data) I just clicked on the "process button" and went to bed. About 5 1/2 hours later DXO had processed the lot and they were spectacular. No supervision needed.

They were sharper, straighter, had had the grain excellently reduced (most were taken at ISO of 800) and looked at least as good as I had ever been able to accomplish through the use of Photoshop and my anti noise plug in. It would have taken a lot more than 5 1/2 hours for me to do it on a picture by picture basis and I didn't see a single photo when viewing them side by side- pre DXO and post DXO- where I didn't prefer the DXO results.

Photoshop can then be used to fix red eye, remove zits, apply various effects etc.

This is an incredible product. If you have a quality digital SLR you owe it to yourself to download and try the free trial offer.
