Just found this article online. I don't see how this can prove we did indeed goto the moon. If it was filmed in a studio, it would still have been lit. Maybe they got lucky filming!! :P
Quote"Global illumination is the hardest task to solve as a game company," Scott Herkelman, Nvidia's GeForce general manager, said in an interview. "Virtual point lights don't do a bad job when the environment stays the same, but a game developer has to fake shadows, fake reflections...it's a labor-intensive process." So when a Nvidia research engineer used the company's new dynamic lighting techniques to show off a side-by-side comparison between an Apollo 11 photo and a GeForce-powered re-creation, the company knew it had a novel demo on its hands.

I saw that yesterday. :)
The whole idea behind that article is that one light source is enough to illuminate that scene in the way we see in the photos, while in a studio they would use several light sources.
It obviously doesn't prove a thing, but is a good publicity for their new processor. :)
