It's funny that the other replies mention the moon and stars. I was thinking of simply taking a shot of the sun, but with a chronometer and compass visible in the picture - oh, and a calendar, too. (As I write this I realize that for any of these ideas to work one also needs some way of measuring angular height to the bodies.
But here's a question of me and the other people who replied -- wouldn't a single shot give you just a LOP?
Intriguing problem! Thanks for posting it, Geoffrey!

Subject: [NavList] Position from a photo
Suppose you wish to covertly record the location of a stash of gold buried in the Sahara desert (say). Could you take a casual looking photo which would convey enough information to make a fix within a few nm of where the photo was taken?
Thanks
