I went to a Native American Pow Wow today and took my DRebel along. I had 3 memory cards with me. I started off with a reformatted 1gb card. I filled that up in a couple of hours or so, and slipped in another memory card. This new card had not been in my camera at the Pow Wow prior to me filling up my first card, then inserting it. Once I put the new card in, I checked to make sure it was empty by hitting the play button on the camera. To my surprise there were pictures of the Pow Wow on it. How the heck did they get there? My first thought was that I accidently put the card I had just filled up back into the camera. So I put the card that I thought was full back in the camera to check it, and sure enuf, it was full. My next step was to put the other card back in the camera to see if there were Pow Wow pics on it. Sure enuf, there were 5 pics on it. How could that be, I had never even taken a pic with that card at the Pow Wow? So my next thought was, maybe I had filled the buffer on my camera, before the camera realized the card was full, and when I put in the new card, it downloaded the images from the buffer to the new card. Well, it sounded good to me at the time, till I realized there were 5 shots on the new card, and the buffer on the DRebel is only 4. When I got home I tried to test this theory be deleteing 2 images from the full card, and trying to take 4 shots to fill the buffer. It would only let me take the 2 shots that the card had room for....
I checked the times that the last shot on the first card and the first shot on the new card were taken. There was 1 min 20 seconds between the two shots. That's about what it took me to to get out another card after the first one was full, and replace it. Then I checked the times between the 5th shot on the new card, and the next shot I took after that. There was over 4 minutes between them. That is when I was going back and checking the old card again, and then putting the new card back in the camera...
Anyone have any idea how this happend or am I going crazy?
