Julian,
A RAW file type gives you the opportunity to use many more tones of color than the JPEG file type. All photographs are composed of tones of color and a JPEG, an 8-bit file, is composed of fewer colors than a RAW type file, a 16-bit file. Since both types of files hold thousands and thousands of colors you might say, why does it matter? It matters because the gradation of the tones throughout the image are smoother and create a more pleasing look and also a more colorful look. We don't actually realize it for the most part when viewing, but it is there and we react to it. You can, at times, see bands of colors in the sky of a JPEG file and this is what happens when there are not enough tones of color in an image so that they can spread throughout the image in a graceful fashion. Thus, a RAW file allows me more latitude in processing since the file will handle the changes better.

Thanks for the clear description of the difference between a RAW and JPEG, 16 bit versus 8 bit. I use PS Elements and have noticed the sky color banding you mentioned when using the Elements Editor on RAW files that I process with the ACR editor. Elements is limited to 8 bit and I often get unexpected color results when I try to bring our more detail in a bland sky. There's definitely a limit to what I can do.
