The shadow knows

The Claim: Multiple-angle shadows in the Moon photos prove there was more than one source of light, like a large studio lamp

The science: The astronauts were taking their photos on a hilly, brightly lit landscape while the Sun was close to the horizon. Imagine taking a photograph of someone on a rolling, uneven field of snow during a full, low-hanging Moon. The contours of the ground would produce shadows of many different lengths.
