Excerpt: The entire camera contraption would have made Rube Goldberg proud, exposing, developing, and processing photographic film onboard a moving spacecraft, traveling around the moon constantly between hot and cold temperature extremes anywhere from approximately 27 to 3,700 miles above the lunar surface. "This thing is going around the moon in zero gravity and developing film," said Williams. "It was an amazing achievement that they could do this." Williams said that the camera had "these big honking reels" of 70 mm film. The film would roll through, the camera would take pictures, and then move the exposed film to an automated developer. The automated film developer contained a mix of chemicals that would develop the film using a process similar to the method used by Polaroid cameras. An electron beam would then scan each developed image before transmitting the photos back to Earth using radio signals -- the same way television satellites would analog signals to TV stations. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
