I'm new here, so hello. Was hoping to get some help. I bought a canon t3i while on vacation, took a ton of pictures with it, and decided I was not happy with it. I decided to have my wife return it and get me a Nikon d5100,, I have some experience with this one and had liked it. anyhow she did not download the photos from the Sd card before returning it. Now when I put the Sd card in the computer it says there its nothing stored on the card. Just doesn't make sense to me. Was a brand nee card also. any suggestions?
