Basically I used to have the sony cyber-shot DSC-S950. After it being misplaced, it was found, however there is a conflict in which a girl thinks it might be hers (she had the same camera). Is there any way for me to compare the pictures taken with this camera with the ones that I took before? I mean, is there a code that is specific to the camera so that I can either determine "yes, these pictures were taken by the same camera" or "no, this is a different camera from the one I had"? Thanks, hopefully you understand what I mean! EDIT: even if you don't have the specific camera, if you know the answer to your own camera and how to find it that will certainly help me.
