All very interesting and I fear headed away from the original question and premise. Skylab was a low orbit, temperature controlled, oxygenated environment where the astronauts could easily maneuver around without any of the moon landing equipment on. Solar charging and stable temperatures means that camera battery life from inside skylab is not an issue. The skylab film would have been transported only through interior cabins and air locked connection ports. So all of the film/camera/hand dexterity issues brought up just recently are a moot point for the film in question. The skylab film can't be explained away by CGI, underwater filming, wires, parabolic flight so.... As far as I can tell it must be real which means we've been in low orbit and could see the convexity of the earth.
Please explain how the skylab film from the first post was faked. I didn't post a movie of the moon landing and skylab didn't go to the moon so it's irrelevant for the purposes of this conversation.
Thank you,
