This looks like a story from some advertisement or movie. A guy found a Canon EOS 1000D while scuba diving in Deep Bay outside of Vancouver. The camera isn’t working anymore. But the SD card still work and he is able to retrieve about 50 photos.
The photos are mostly a family vacation. He is also able to tell that the owner has a wife, 2 year old daughter and is a fire fighter from British Columbia whose team won the Pacific Regional Firefit competition. From the EXIF data, he is also able to tell the photos were taken more than a year ago.
So with the help of Google Plus, they found the owner of the camera. Amazing but true.
In case you are wondering, the SD card is a Sandisk Extreme III. But then, memory cards are known to survive underwater.
