Quite aside from Tarkus' failure to provide references, and clear lack of understanding in photography and photgraphic analysis, there is another failure on his part, a basic mistake that is made by a good many poeople and one that they don't often understand even when you try to explain it to them.

He posts pictures of the moon and, while he probably realises the moon is a globe, he argues through the photos, which are a two dimesnionsl representation of a three dimensional object, as though it is flat.
