The Matter of Perspective
The London Royal Museums Greenwich website quotes Professor Anu Ojha, the director of the British National Space Academy. He explained the parallel shadows issue, saying that scientists can reproduce the effects on Earth. Everyone has seen the phenomenon themselves where the parallel lines appear non-parallel.

Ojha also said that you can make lines do weird things when trying to reduce a three-dimensional situation into a two-dimensional plane. Artists have done so for centuries. Then, he debunked another photo issue. The “truthers” claim that the moon mission photos showing the sky don’t include stars, which proved the astronauts weren’t in space.
