Thank you Edward, Lurkalot and Dave. I will indeed go back and review this whole thread as I know it will give me great advice and help.
I just starting into bird photography (see my web site www.trubrit.net).
I am hoping that our local college has a class on photography that I can take in the autumn.
I will definitely go back to JPG for my trip, and just play with RAW now and again until I have a better undrestanding.
Thanks again! You guys are great!
