I wish I could shoot in raw - being able to get the pictures before color correction happens would be great.

Me too - I'm thinking about buying a new digital camera with RAW output - I seem to spend a lot of time fixing JPEG artifacts in my photos.

Great clip - a very good demonstration of the differences!
