So I'm photographing a rehearsal dinner and wedding this weekend. Very low-key for a friend of a friend. She knows I'm not a professional. Other than photos of her getting ready the whole deal is probably only going to last about three hours. I've only recently begun shooting in Raw and have found that my patience for the uploading and converting process to be very thin. I have two 2g cards and one 512mb, so shooting in raw gives me about 400 frames, whereas shooting in jpegfine would give me around 600, give or take. I plan on giving her a cd with all of the images and she wants help creating a photobook. Is it worth the extra time to shoot in raw? Do I need more memory cards? I figured if necessary I could have my laptop nearby and upload the images from one card while shooting with the others. Any advice would be greatly appreciated.
