hey there Jeff...
While I agree with your assessment that if Zapruder was not panning his camera - everything SHOULD be in focus... but once he moves the camera along with the limo you can only get one of two things:
1) the limo is clear while the background is not (unless the frame rate is MUCH faster than the panning movement) or
2) the background is clear (stopped panning) while the limo - which was supposed to keep moving - is not
If both limo and background are clear... both must be stationary along with the camera - otherwise ALL would be blurry from the panning.
Agreed?
With regards to a framerate we can agree upon... 18.3 works just fine 48/18.3=2.623.... although the math gets more muddy.
For our hypothetical discussions and for ease of math, 16fps will be fine.
If you can explain/illustrate how you feel the spring would change the fps so drastically as to make Greer's movement possible - I'm ready.
Page 1195 of Horne's Zfilm chapter offers the FBI tests on the fps rates of the camera throughout the 25 foot / 60 second cycle.
For us to miss frames per your explanation the fps would have to be SLOWER than 18.3 at the time we are talking about.... (more action in fewer frames)
The assassintion is captured on the f[B]irst 7 feet [/B]of the film's side B... the FASTEST portion of the spring's unwinding and
according to Horne's recap the 1st 10 seconds is 18.0-18.1, the 2nd 20 seconds of film (the HEART OF THE ASSASSINATION FOOTAGE) would be 18.3-18.5fps...
Finally, the only time the fps drops below 18 is in the last 20 seconds of the film... to 17.6-17.9fps
If the film was NOT done in slow-motion, and followed the film map, the entire assassination is on the first 7 feet of film.
the film is .149" per frame, there are 84 inches in 7 feet therefore about 564 frames in 7 feet of film, more than enough to capture 486 frames...
How do you reconcile your thought that the camera was moving SLOWER during parts of this sequence at the beginning of the film when the spring was wound the most?
And how much slower are you claiming it to have to go for what we see to happen?
Thanks
