Thanks Rene-I guess my real question concern was if the RGB tab would actually effect the CR2 Raw file also. When I monkey around with both the Raw and RGB tabs, as you said, I do have more options such as the curves feature in RGB. I did not know if it applied if you were to make the Raw in to a JPEG file. Glad to know I can use both tabs and it will apply to the CR2 file and not just the RAW tab only. Makes me feel better knowing I have more control now. Thanks for the help.
You are misunderstanding some things!
The Raw file consists of some chunks, including Exif and other data that the camera puts in there, but the image data is binary image data that is simply recorded by the camera and from then on it is read-only.
DPP follows the Raw model in this. The one thing DPP can do that other Raw processors typically don't is that DPP records editing data in the chumk of the file that includes Exif -- it is metadata that DPP can retrieve if you open the file again, as long as you have used DPP to save it. Other Raw processors don't read that metadata, meaning that if you edit a Raw file in DPP those edits won't show up outside of the DPP editor. They are only applied to an actual image when you convert and save the image to a jpeg or tiff. The Raw image data, though, will continue to remain unfazed and can be rerendered to anything you like.
There is also a chunk of a Raw file that contains a jpeg preview image, embedded so you have something to look at in the camera and that flashes in front of you in some software and that other software can simply use it to allow you to view your images. That jpeg has been rendered using your in-camera Picture Styles and other settings, so they can look significant differences between that preview and what you see coming out of many Raw processors. DPP by default uses the camera settings to render a preview, but you can tweak those settings to create your own look.
