As I'm thinking most Photographers take a lot of photo's, and after they import them onto their computer, they would either store them on the camera for a little bit or delete them. When I hook up my Sony Cybershot to my Macbook, it appears as a memory stick on the desktop with different folders containing the photo's. In order to delete I have the option of the "delete imported photo's" in Aperture/iPhoto or dragging to the trash. But I'm sure there are better/easier ways to delete photo's off a camera as with the large amount of photo's that some people take, dragging to the trash can be an annoyance. So how do you delete your photo's?
