This looks interesting…. just drag and drop the photos from your missing DSLR and this website will use the EXIF data to crawl and search the web to help you find out where your camera is. Haven’t used it personally and I don’t know if it works.
But it may be worth a shot if you lose that precious DSLR or digital point-and-shoot of yours. So keep the info handy and don’t forget to share this too.
