I recall that when I was 10 or so, my exceptionally religious aunt (the one that gave money to Jim Baker) had a photograph of a cloudy sky wherein a cross was superimposed such that it appeared to be floating in the air. At the time I did marvel and wonder how such a thing could exist, but even then I looked for a mundane answer.
Thank you The Amazing Randi and related reading for all that information on double exposures, forced perspective, and other tricks for lying with “photographic evidence.”
