Possible Anomalies in the Apollo Lunar Surface Images

The Apollo Moon Landings took place 43 years ago.  While the world has moved on to other matters, and the drama of the event has somewhat dimmed, the Hasselblad images from the various EVAs remain as the definitive testimony to Man’s first steps on another planet.  With the advances made in technology over the intervening years it has become possible to take a fresh and analytical look at this aspect of the Apollo photographic record.  Disconcertingly many photos have been found to contain inconsistencies, anomalies and unexplained details.

Marcus Allen trained as a photographer in London in the 1960s when he became familiar with Hasselblad cameras.  He will be presenting a selection of anomalies that have been found in the Apollo lunar surface images.  He undertakes not to put forward any personal views or conclusions regarding these findings.  The presentation can then be followed by a full discussion.


Marcus Allen now lives in Sussex where he finds the time to publish an International magazine while pursuing his interest in photography and a garden rapidly escaping his control.
