Gracias rodeo joe, JDMvW, conrad, BeBu, SCL and everyone for your responses! I can see that the scope of this subject is quite wide and that my best bet is getting out there and shoot in order to get the knowledge! It's interesting to see that many of you have been quite active before the advent of digital cameras. My only experience's been with digital point-and-shoot cameras, and it's only recently that I made the jump from jpeg to RAW. Thanks again!
