I love my new camera. Remember the old days, when you had either 24 or 36 exposures in a roll of film? You had to be careful not to waste any. Yesterday, my Kodak 32-gigabyte SDHC memory card arrived via United Parcel Service (in a ridiculously wasteful package, for what that's worth). My camera says it will hold 7,477 medium-sized images (3,456 x 2,304 pixels). If I set it at the highest picture quality (5,184 x 3,456 pixels), I can take 853 images. If I set it at the lowest quality (2,592 x 1,728 pixels), I can take 9,999 images. A bit more than 36, wouldn't you say?
