Last September NVIDIA announced that with their Maxwell GTX970/980 graphics cards and Global Illumination software, they were able to determine the cause of Buzz Aldrin being illuminated on the shaded side of the Lunar Module in the Apollo 11 photographs.
Only last month did they finally release that demo. Predictably, they didn't dare release it with adjustable albedo settings, and so the user cannot know how bright the cgi landscape actually is. But as luck would have it, the demo comes with a "Colour Only" mode, which allows one to see the colours of the surfaces without any lighting. After a simple comparison of the Red Green Blue values of the colours used, it has become clear that the computer generated lunar surface was NOT 12% as NVIDIA claimed, but 30.6%.
Special thanks go out to NVIDIA customer Bo Chen.
The following is a list of the "visual normal albedo at 5% phase angle" of various lunar features. These numbers can be used to directly compare to terrestrial surfaces (reference cited below):
Darkest areas: 8.6%
Tranquillitatis south of Plinius: 9.1%
Plato's floor: 9.6%
Serenitatis east of Linne: 10%
Imbrium south of Plato: 10.4%
Nectaris: 11.4%
Ptolemaeus floor: 13.1%
Arzachel: 17%
Tycho ejecta: 20%
Aristarchus: 20%
Aristarchus interior: 22%
Bright spot in Deslandres: 24%
Proclus E wall: 28%
Stevinus A, Abulfeda E: 30%
These values are, as you can see, considerably higher than the other lunar albedos given. For comparison, the albedo of a green golf course is about 13%, roughly the same as that of the Cayley Formation which covers the floor of Ptolemaeus. So you see, the moon is not quite as dark as is often claimed - something about in the middle range of lunar brightnesses is just as bright as a grassy yard at noon.

But that is akin to using the bible to prove the bible.
How can we trust NASA's word if we believe NASA is behind the hoax?
Nice that you criticise Jarrah's findings, but what about NVIDIA?
Thats a major company who is using the moon landings and the conspiracy surrounding the landings
to promote their product. Do you not question their decision not allowing us to
play with the albedo settings ourselves? What is there to hide ?
