This is strange. Apparently a camera has an internal memory for photos outside of the memory card? Because my "problem" memory card-with the lost pictures-- is at Wolf Camera where they tried to recover them. (They couldn't.) So I dug out an old card that I didn't have with me on my trip (the trip where I had lost a day's worth of photos) to take some pictures and when I scrolled back through, there were the missing 50 photos! And now all the other photos that were origionally on that card are missing. Is my camera messing up?
