Why Neil Armstrong was camera-shy

One of the most unusual and oft-used pictures showing Neil Armstrong on the moon is this one, which is actually a reflection of a lunar scene on Apollo 11 crewmate Buzz Aldrin's helmet visor. The reflection shows a fuzzy image of Armstrong holding the Hasselblad 70mm camera, with Aldrin's shadow stretching in front of him. Armstrong is flanked by the lunar module and scientific experiments. The cross is a "fiducial" mark used for calibration. For more about the picture, check out an analysis from the Apollo 11 Lunar Surface Journal.

The reasons for first moonwalker Neil Armstrong's reticence on Earth may be psychologically complex, but there's a simpler reason why pictures of him on the moon are so scarce: In addition to being the commander of the history-making Apollo 11 mission in 1969, he was the chief photographer for the mission's moonwalk.

Nearly all of the pictures that were taken during the first moon landing show Armstrong's sole crewmate on the moon, Buzz Aldrin, because Armstrong was stuck behind the camera.

But it'd be an overstatement to claim that there's only one picture showing the recently departed astronaut during his lunar walkabout. All you have to do is notice that different people have pointed to different pictures as the "only one."

Armstrong may have taken most of the scores of photographs that were captured on the lunar surface, but Aldrin also had a couple of turns behind the Hasselblad 70mm camera, and there were other cameras as well: the famous TV camera that transmitted that "one small step," and a 16mm movie camera that was looking out a window from the lunar module. "The Cameras of Apollo" website provides a rundown. 

Take a look at these pictures showing Armstrong during the moonwalk, then take a spin through our slideshow featuring the highlights of Armstrong's life, before, during and after Apollo 11:

Some frames of Neil Armstrong working on the moon were captured on a 16mm movie camera that was set up on the Apollo 11 lunar module to record the action. This high-definition scan of a movie frame provides the clearest view of Armstrong's face while he was on the lunar surface. That's because Armstrong had raised his gold-colored outer visor while he was working. Check out this CollectSpace tale about the picture.
