"... correct and incorrect exposure and color values on the Web needs to find a good optometrist."
And if they can tell the diffrence between a jpg or RAW edit on Fakebook, they are truly gifted.
You can only push/pull the shadows/highlights so much in a jpg. A person's skill in PS will allow more manipulation without too much noise, but you can't manipulate data that are not there. RAW files have access to data that aren't there in the JPG. Cleaning up shadow noise is one thing, but blown highlights on a JPG are nothing more than white pixels; with RAW there's often still data there.
I also prefer to adjust my exposure, if needed, during RAW conversion because it's cleaner. But I agree with your overall point - that you can 'bend' the exposure of a JPG in photoshop (a reasonable amount) without being noticeable in a web-sized picture.
I also find color manipulation, particularly skin tone for glamour/portrature, to be much easier and smoother in RAW. But I do posses the ability in Photoshop to make similar changes. Though if Facebook has taught me anything, it's that the majority of people out there do not possess this ability.
They are from my new canon 50D. I am trying to STICK to RAW format,, I did take you advice and downloaded the picasa program. IO have had THAT program before. also ONE-Drive will also allow me to view the raw images,, but,, I just am not "warm and fuzzy" with having to use hotmail log-in to gain access to one drive.
