Sandy, I have enjoyed your post on looking at the BYP's with a stereo viewer. I would like to do this also. I was a photographer for 40 years, and a little of my work was stereo. I thought I would like to share a little information on stereo imaging. To achieve a stereo image, two images need to be taken with a slight difference in the camera position left and right. Most stereo cameras have two lenses that click at the same time, creating two images side by side. Most stereo cameras have the two lenses 2 1/2" apart from each other. You can also create stereo images with a camera with one lens, take the 1st picture, then move the camera 2 1/2" left or right, and then take the second image. This conforms with how far are eyes are apart from each other, and this is why stereo works, as the brain interpolates the two images as if seen by two eyes. Moving a camera up or down would not achieve this effect. I recently acquired an Imperial Reflex Duo Lens camera, identical to the one Robert gave the FBI. It does not have a tripod thread mount on the bottom. IF the BYP were taken with an Imperial Reflex, a slight shift to the left or right between two pictures could achieve a stereo effect. I think that is what you were seeing.

Hello, My name is Ted Hammond. I have been a photographer since 1966. At the University of Minnesota I was asked to help with JFK Assassination photography in 1968. I was given negatives and asked to print them, given prints and asked to make negatives and enlarge the prints, etc. I also helped a researcher with the Zapruder film as he gave talks at colleges on the assassination. I was given a copy of the Zapruder film in 1969, and have studied that film for many years. I pulled away from the research for many years, and am now retired and have regained my interest. I am very interested in the research being done on this page and have great respect for the people and posts. Thank you for allowing me to be part of this group.
