Gerphal - I hope you are psychic indeed. I often find great things in images that I didn't expect to produce such value. So with storage space as inexpensive as it is, I just shoot 14-bit, uncompressed NEFS plus a basic jpg., for quick transmission from the field for me newspaper work -- something so they know I am bringing the "goods" back. But I don't see the need to produce anything less than the best for keeping. I carry my cameras everywhere with me. I tell people it prevents major air crashes, since if I'm ready to photograph them, they won't happen!
