This photo, as it is usually presented, is actually not the view that the Apollo 8 crew saw looking out of the command module window. This is. The lunar orbit of the spacecraft was essentially around the moon's equator with the moon always oriented on the port (left) side of the ship. From the astronauts' point of view, the Earth was not rising "up" over a horizontal horizon. It was, instead, coming into view with the Sun on the right side of the ship and the moon on the left side. And that is actually how Frank Borman, James Lovell, and William Anders saw the Earthrise from Apollo 8. Their famous photograph was rotated 90 degrees counter-clockwise after-the-fact by some NASA PR person, and this is what most people assume was the view of the astronauts.
