All the Apollo astronauts did was have two tiered windows with a gap down the middle of them. They used various sized transparencies of the Earth to equal the different times they filmed according to how far away they were meant to be from the Earth.

Within the gap of the two windows they had the transparency covering the main real window. While moving a fake Earth transparency across from one side to the other side of the window, they also had in the gap on top of the transparency a blackboard that was moved across in tandem just behind the main transparency.

You can actually see in the above video at 4:43 just as the fake transparency of the Earth is disappearing to the right, the blackboard following right behind. You can see the straight diagonal line of the blackboard going up & down. Then suddenly at 4:39 they slam the blackboard shut blocking out any incoming light.

Again in the same video at 3:52, the fake transparency of the small Earth at the right, then they close the blackboard over it and all light disappears.

Also at 2:17 you can see the straight diagonal line of the blackboard coming across to the right over the fake Earth transparency, then at 2:11 the black board is
slammed shut.
