Seven Astronauts on Moon

Digital photomontage of seven astronauts on the surface of the moon was produced from an original photograph made in 1969 by NASA of a single astronaut, Edwin F. Aldrin, Jr. This montage is of high technical quality; it is carefully contrived to seem spatially consistent, and sophisticated digital technology has eliminated any obvious signs of cutting and pasting. SO HOW CAN WE TELL IT IS A FAKE?
There is an obvious internal inconsistency. The reflections in the visors are incorrect. Each shows the image of just one other astronaut, not the several we would expect.

There are some questionable cast shadows. The artist had to insert these with a digital "paintbrush" and faced with the difficult task of making them consistent with the rough terrain.
