After many years of film -- the last five with my trusty Nikon N80 -- I'm switching to full-time digital, I just bought the D70s, an 18-70 Nikkor lens and a b+w circular polarizer. I've read a lot about the importance of white balance, for example, and about the different file types you can save your shots in (basic, raw, raw+basic, etc). Any guidance on these two areas especially, or other tips, is greatly appreciated. PS I'm new to this forum, too, and I am really enjoying reading the posts.
