Finally someone agrees with me the the in-camera noise reduction (in my case xti) is better than DPP! Common Canon, make this a top notch program!!
I've just now started trying Noise Ninja which works very well. Very impressed - just have to shell out the bucks for it. I may start shooting RAW now.
DPP just makes me mad cause its so close to being really good and I really want a good free tool (cause I'm cheap) that comes with my camera. Just needs better noise reduction, highlight recovery, and lens correction for my 17-85.
Oh and rotate!
