re: Apollo 12 pan from APOD
In the middle of the pan at the bottom of the picture out in front of the American Flag, I believe that is a shadow of an Astronaut.
If you look at the head part of the shadow on the ground stretching back toward the flag you can see a bright spot like a light probably used to illuminate the scene especially the flag (notice the shadow of the flag slants away from this camera light) note that the area on the far right of the pan even out in front of the Sun is kinda dark so they apparently used artificial lighting for the photograph.
