I think you might have added the JPEG files are subsets of the information in a raw file with the rest of the information permanently thrown away. A raw file contains all the shooting information when an image was captured. A jpeg does not contain a significant amount of that shooting information, which is why raw files can be edited more successfully and with better results. I'm always amazed by those who think there is no advantage to raw files in post processing. Those of us who post process most of our images know that isn't true.

I do not do a lot of post processing but I do like the flexibility that RAW files offer. When in Sedona my wife and I took a Pink Jeep tour of the National Forest. It was very four wheel drive, bumpy, rugged and also beautiful. No tripods but the driver would stop on occasion for photo ops. Not a lot of time to compose and very easy to over/under expose so it was very similar to drive by shooting.

The first photo is what I shot, the second was the result of a little bit of straightening and processing in Lightroom. Ended up getting a nice memory shot that, if I had been shooting jpeg only, might have missed.
