I’m no pro photographer but I understand the basics of shooting and processing. Today I did a little experiment with RAW versus JPEG. I took some paint to a clean piece of paper and shot two images: one RAW, and one JPEG. I’ve always known that there is a HUGE difference in quality but never actually took the time to compare. The difference in detail is impressive to say the least. These are straight out of the camera, no adjustments have been made except for cropping. Both shot at the same speed, aperture, and ISO.
Here is an easy read and great article from Photography Concentrate on 10 Reasons Why You Should Be Shooting RAW. Enjoy!
