I have opened the same raw image from my Canon EOS 550D (CR2) in Lightroom and Digital Photo Professional. This are the default raw development results:
Lightroom: 
Digital Photo Professional: 
Why is the image developed by Lightroom so bad? If I manipulate the settings (white balance and so on) in Lightroom, I even get worse results than in Digital Photo Professional (default settings). I cannot figure what’s wrong.
Developmode, scroll down to theCamera Calibrationpane, and see if you can change theProfile. Most of the time it is set to Adobe, but you probably can change that to another profile. See if that helps your problem. – Bart Arondson Sep 19 '12 at 15:05
