John, if you think it was easy to detect fakes, I suggest you look up the details of the famous "fairies" photos in Britain in the late 1800s. Fooled an awful lot of people at the time, and weren't conclusively "outed" until the kids responsible owned up. Of course, the subject matter made it a moot point, but the fact that even schoolgirls could do a good fake with an analogue camera in the late 1800s says a lot about the trustworthiness of analogue.
