Recently I discovered Web sites with some interesting 360 degree pictures from the five Appolo missions that allegedly made it to the moon. What I notice about the pictures is, if these pictures were actually taken on the Earth, then the perspective is all wrong, as the horizon appears to be way too close in the pictures taken on flat terrain. Faking the picture by bringing in the horizon wouldn't work, since that would distort everying else - standing objects would look too skinny, circles would look like ellipses, etc. On the other hand, if the pictures were taken on the moon, which has 1/4 the diameter of the Earth, then the altered perspective makes perfect sense.

So, for all you conspiracy theorists, how do we explain this? Personally, I'm stumped on how they pulled this off.
