JFK assassination film hoax
The hole mistake
When the forgers made the frames of the Zapruder film, they probably thought that they would never have to actually show anyone an actual “original” 8 mm film. All they needed were images that could be published by the U.S. Government.
In the same magazine issue described on the last page, one of the Zapruder film frame images showed the edge of one of the “sprocket holes”: the little holes down the side of the film that the projector teeth grab onto:
Apart from the ridiculously long forearm of the Secret Service agent, nothing seems to be out of order with this image.
It was 33 years before the public got another close look at the edges of any of the sprocket holes. The “original” film was digitally scanned, and some of the images published on DVD in 1997.
When scientists looked at the same frame on the DVD image, they got a surprise:
The DVD showed the sprocket holes for all 486 frames of the film, and researchers had studied and measured them carefully. You can see clearly where the sprocket hole is: it is the white area (a rectangle with rounded corners).
The problem is that, in the 1964 image, the rounded corner of the hole clearly crosses over a bright smudge of light (caused by the way the camera was designed) and runs down to the right of the white area. Between the two is a pale blue area.
This can be seen more clearly when the two images are laid on top of each other:
How can a hole be blue?
It can’t, of course. If a genuine film was photographed (being lit from behind, like a slide or an X-ray), then any hole in the film will be white.
Scientists believe that the forgers created the images by first exposing a photographic film with the frame image (in this example, the limo and Secret Service agent, etc.) as well as the right parts of the next frame and the previous frame that would bleed over in the area between the sprocket holes (the bright smudge of light you can see that goes up to the armpit of the Secret Service agent). Then they created the sprocket-hole shapes by doing an extra white exposure, with just these hole shapes.
This seemed to give nice white sprocket hole shapes, but the forgers didn’t notice that where there was only the “hole” exposure plus the exposure of the dark blue limousine, the result was only pale blue, not white.
By the time the “original” film was scanned for DVD in 1997, the round edge of the “hole” had been changed slightly, so that it looked like the left edge was the “real” edge of the sprocket hole. You can see the change above, especially in the corner where the two edges cross.
What was left was a “halo” around the sprocket hole. Similar “haloes” can be seen on many frames of the film. Researchers in the early 1990s had wondered where these “haloes” had come from.
The frame published in 1964 gives us the answer: the sprocket holes weren’t really holes at all, but “triple exposures” of light. Where there was only a “double exposure”, you don’t get something completely white, but instead a pale version of the object that is underneath.
This is yet another mistake made by the forgers. Maybe they didn’t anticipate how much scrutiny their forgery would get in the years and decades afterwards.
But it was good enough to help cover up the assassination for the rest of their lives, wasn’t it?
