Ten years later, for it’s 30th birthday, a new audio format – SACD or Super Audio CD – allowed Pink Floyd/EMI to present to us a superb high-res surround sound version of the album. This most celebrated of albums was reissued for it’s 20th anniversary in 1993, but in those days putting a newly remastered CD in a bespoke box with a few nicely designed ‘art cards’ was considered a deluxe treatment. So, after almost six months of anticipation, expectation and speculation, Pink Floyd’s The Dark Side of the Moon Immersion Box Set has finally arrived. Here’s a great run-though of the lunar landing photos and how lighting on the Moon works.The new Immersion Box delivers the ultimate Dark Side of the Moon listening experience across 6 discs Some people have used this as “proof” that the landings were actually filmed on a sound stage under artificial lights, but in reality it’s all due to reflected light. Astronauts within the shadow of the landing modules were still visible, and their suits were well illuminated by reflected light from the lunar surface. It tends to reflect light directly back at the source, and will illuminate objects within shadows as well - as seen in Apollo mission photographs. Lunar regolith is composed of fine, angular particles of very reflective dust. Buzz was well-lit by reflected light, even in Eagle's shadow. Shadowed areas are dramatically murky, like in the LROC image above, yet there’s still some light bouncing around in there - this is due to reflected light from the lunar surface itself. So shadows are very dark and, where sunlight hits, very bright. On the Moon there is no air, no Rayleigh scattering.
