Follow the little red ball... The first photo is one from a famous smoking-gun series of Aldrin supposedly coming down the LEM ladder. In the series, the photographic fill-light used to illuminate the back side of the LEM, and Aldrin, is very visible as a point reflection on Aldrin's boots. That reflection can still be seen in this photo, and shown zoomed in on in photo 2. Even more revealing is the tell-tale point reflection on the red ball (CO2 release?) on Aldrin's suit (Photo 3). Being that it is tucked under Aldrin and far inside and away from the outside edge, the reflection cannot possibly be reflected light from the surface. The yellow arrow points to the point reflection at the center of the ball. But even more telling is that the fill-light is seen to "smear" around from the point reflection because of the curvature of the ball. This is most evident to the right of the point reflection (Green arrow).
