I bought the camera about a month ago but the card is quite old. I took a bunch of photos today and when I came home they were all gone... Tried to take new pictures, it works fine. The pictures I took yesterday are still there.
I didn't intentionally review the photos after taking them today but each time I take a picture I see it on the screen for several seconds.
Does anyone have any idea as to 1) what happened and 2)whether it is possible to retrieve the pictures? The only explanation that comes to my mind is that maybe I didn't insert the memory card properly. But that would be strange because normally if it isn't inserted properly it's really obvious. And if there's no card the camera says so.
