All I know is that since I recently bought my GRD III I have been having a lot more fun with my photography. Plus this sight has helped a lot in that matter too. I keep going around and around on this JPG/RAW thing but have come to the conclusion similar to pictor. Do it right in the camera first!!!! However, like slide or print film, everything the camera did to make that image is on the film as is the data on a RAW file.
BTW, I hope all of you Americans had a great 4th of July!!!
