Lucky you, a vacation in Paris. Lucky you, a 5D Mark III... I saw someone taking HDR shots with that camera. You don't have to do any work - just take the shots and the camera assembles them! Enjoy your new camera, macaroons and Paris!
Jealous of Paris, the new camera and the macaroons. I agree with @cocobella Ladurée have THE best macaroons, you should not miss them. Have fun with everything else and don't forget to get a picture of the sparkling Eiffel by night (I think it's every full hour or so) :)
Sure Danton would have love them !
