Hi all. First post! Exciting. I've been reading, learning and enjoying all of the posts and photos put up by the community. This is my favorite site for Canon stuff - Bryan is awsome. Just curious as to how addicted I should be to using my grey card. I love it. I recently read about using a white card (in place of the grey card)incertain conditions. How much do you guys use (if you use one) your grey card?
