I just got the 50D yesterday and took some test shots, but I am unable to open them in Photoshop. It says file type not recognized. I am shooting RAW. I searched for a solution, but didn't find anything.
make note that DPP will open and process the RAW file and present it to you with whatever picture style is set in the camera. The style does not affect the RAW, just gives you a starting point/option.
In DPP, you will be able to select any of the picture styles....the standard is most common for saturated/pre-sharpened JPG
