A Stereoscopic method of verifying Apollo lunar surface images
This site is interesting in a Physics PhD from the Ukraine maintains that the Apollo moon photos are all faked and taken in a studio. By various parallax and other calculations it shows gif sequences of two photos where the hills/mountains in the background are some kilometres away. These mountains are subject to movement which indicates that they are not kilometres away but merely metres away and ...
that the ‘lunar’ mountain backscape was projected onto a forward-tilted, slightly convex, circular panorama background screen
Anyway, I hope I have summarised it correctly but there are many examples to illustrate what they have done and found.
