'Return to owner'Take a photo of a sign you make that says "This camera belongs to ..." and lists your name, contact information, and (perhaps) the promise of a reward. Set this image to "read-only" to make it difficult to erase. Keep it as the first picture on your memory card. If strangers find your lost camera and start looking at its photos, they'll know it belongs to you.
