This past summer, while hiking at The Basin in New Hampshire's Franconia Notch State Park, I spotted a shiny object at the bottom of the rapidly-flowing river, near the footbridge going to the Basin. With some help, I was able to reach out far enough to retrieve it. It was a Sony digital camera, completely rusted out and totally destroyed, from months of sitting in the cold river.
Being the geek that I am, I decided to take it home. I thought that, since memory cards are solid state (no moving parts), there might be a very slight chance that the photos could be somehow recovered, even though the camera had been submerged for months. Plus, I thought, if I lost my camera and another geek found it, I would want them to at least try, right?
When I got home later that week, I took it out to my workshop and, using a screwdriver and needle-nose pliers, I carefully took the camera apart, trying to pull out the memory chip. Since the camera was so corroded, I needed to literally remove the chip from the inside guts of the camera, being careful not to damage it.
The contacts on the chip itself were very corroded too, so I cleaned them up with some fine steel wool and contact cleaner.
Next, since I did not have any way to read a Sony MemoryStick, I took the chip down to my local photo center, to see if their card reader could find anything at all on the chip. I was amazed to find 244 photos and 25 movie clips on the card!
