As I was packing up my camera after photographing from the Canadian side of Niagara Falls, two men came up and asked if they could see what I was shooting. I said, "yes," and pressed the play button on my camera to display the last image I took that morning.
Without asking, one of the men rotated the jog dial on the back of my camera to see the other images I captured that morning. But he rotated it clockwise, and instead of seeing an earlier image, the camera displayed the first image on the memory card — one I took four days earlier.
"Wow!" he exclaimed. "Is that Niagara Falls?"
