Allen, I believe it a line-of-sight difference between Zapruder and Willis.
This is the Charles L. Bronson photo, taken about Z225-227. The Stemmons sign is roughly edgewise to Bronson's camera-view.
Willis's viewpoint had most of the Umbrella Man beneath the bottom of the Stemmons sign. Zapruder's view towards Umbrella Man was more elevated. And so in the Z-film the umbrella was seen higher up along the edge of the sign. As well, the umbrella itself was raised more (maybe a foot higher??) in the Zapruder film and Bronson photo than it was in the Willis photo.
I see no reason to believe the Umbrella Man and Waving Man changed where they stood between Willis05 photo and the Zapruder film. There was some space between them. The Zapruder film shows the Waving Man away from the Stemmons sign because he stood on the street edge of the sidewalk while the Umbrella Man stood on the top of the raised curbstone between the sidewalk and the grassy slope.
Thank you for sharing that. I appreciate that. I am open to logical solutions and I can now see the perspective better that has been put forward. I still think the elevated umbrella in the Zapruder Frames are showing a very close proximity to the car. I think the umbrella should be further over in order to conform to angular alignment. The sign itself must be about 4 feet high. Zapruder's perch is quite a bit west of the sign.
I think no matter which way you look at it, given Zapruder's elevated position, the umbrella man should be over about where the black suited man is in the Willis' photograph below the sign in my opinion and then have the umbrella moved over to match his position. To me, that would be the logical placement, matching the bush up above outside the sign!
He is being shown on the outside of the corner post of the sign which lines up with the motorcycle antennae on Willis' photograph The angle doesn't look right.
At any rate, unusual for a man to be using a fully extended umbrella on that day and it appears JFK and JC are looking right at him. The SS in the followup car as well. Again for me, I can see this as an attention attraction. I would never buy into the umbrella having some sort of weapon built in. I still suspect the angle of the bullet to the neck came would be more logical in a frontal shot coming from Nellie's side from the person whose hands disappear behind the body after finishing the "clap" - very rapidly. This being when the car was behind the sign in the Zapruder film.
I can't find those 2 people one black and one white? on the Bronson frame. They must be right at edge and not captured!Again it has always been my speculation that it was a well coordinated event and when Jean Hill heard 2 shots, she was correct. A second almost simultaneous noise (shot) from up the knoll will have everyone looking in that direction. That is from her TV interview on the very first night.
Thanks again for sharing the Bronson film frame and that information which is a good rebuttal - not just none sense. I assume that was from his movie camera and that it has been enhanced and blurriness removed.
