Here is an interesting comparison found on the Japanese Kaguya mission site. The two images shown above are of the Apollo 17 landing site. The top is obviously a photo taken on location by an Apollo astronaut and the lower image is a render from data taken by Kaguya in orbit around the moon. When programmers compile their data to show how the moon looks from the same position as the original Apollo photographer, the results come pretty close to matching. Such a comparison offers an idea of how real other such renders we may see from the mission can be trusted.
