Two services that search web images for the serial number of the cameras that shot them are helping to re-unite owners with their lost and stolen cameras. Both work by looking for the serial numbers embedded in images uploaded to services such as Flickr. CameraTrace, which costs $ten per camera, now includes a monitoring service that updates you lot if new images are posted. You also receive an identification tag for your camera, to assist recover it if lost, rather than stolen. Stolen Photographic camera Finder, meanwhile, requires only that you drag-and-drop a file from your camera for it to read the EXIF and start searching for public photos with their metadata intact.

Although hardly flawless (neither tin can search Facebook because it strips EXIF information and some cameras, including all Sonys, don't include their series numbers), both sites have led to photographers being reunited with their cameras. (via Sydney Morning Herald and PetaPixel)

While not terribly numerous, the light-green 'constitute camera' flags suggest information technology's worth using the services to look for your lost or stolen camera.
