"Composite" does not imply "faked." Someone's implication here appears to be that the image presented would not have been visible to a human orbiting the moon at that time and that place. As far as I can tell, it is an accurate representation, even if a composite.
Most color images from space--Hubble, the Mars probes, Cassini at Saturn, etc.--are composites, and often false-color at that. However, at the link provided, it explains how the image was created.
The images were taken on Oct. 12, as the moon approached "New Moon" phase ("Full Earth" from the moon). Thus, the visible side would have been in darkness, and the far side would have been illuminated. The illumination appears to be coming from behind and to the lower left of the orbiter, which is where the Sun would have been at that time and orientation..
The lunar orbiter is reported to have been about 85 miles above the surface, and part of the crater Compton is reportedly visible on the surface. Compton is located on the far side of the moon, but near the limb, and because of libration (a slight turning of the moon from side to side as it orbits), is sometimes visible from earth--so it is very close to the edge. Some of the mountains/crater rims are not illuminated by the sun, but are silhouetted by the earth, which is consistent with the reported position of the orbiter, the earth, and the moon.
So, I am curious about what is so evident that it is 'faked," and not a legitimate composite image?
