This is an article Gavin wrote over at Seim Effects recently regarding Raw vs Jpeg and their usability with presets and good workflow techniques.
As a photographer I shoot in the RAW file format. I find more flexibility in post production, and ultimately a better image quality with less hassle. When I was still in the Jpeg camp, I was told to shot RAW mainly because it was faster to edit! While using Jpeg I never quite got it, and felt my Jpeg workflow worked fine. Then I tries RAW! I soon realized that it was not only faster, but also had better quality. Now I know there’s some debate on this issue, but I feel I can get great images easier with RAW because there’s more information on the file to work with. It just makes sense.
Having said all that there are still Jpeg shooters. In a poll on Pro Photo Show we found that raw shooters currently make up for about 75% of photographers towards the advanced and pro end of the market. Of course the closer you come to consumer shooters the more Jpeg you’ll see
