So I just got my 20D today and I'm using a 28-135mm. I've read the manual and a few 'cheat sheets' online to learn how to do the settings on the camera, but as far as how to tell if I'm using the best settings would it be best to shoot in RAW or JPEG. I understand the difference of when/why you want to use each, but from a learn standpoint, which is better?
THANKS!
