the logic of Zapruder film alteration
Chris Davidson replied to Roger Odisio's topic in JFK Assassination Debate
Perhaps this reenactment will help: Don't forget to locate the "Portable Pedestal" too. -
Has the Z-film ever been "recreated?"
Chris Davidson replied to Aaron Sharpe's topic in JFK Assassination Debate
Welcome to the forum, Aaron. https://vimeo.com/911660532?share=copy -
Speaking of a 10" vertical, I believe you could describe one of the head shots as a 3ft "short of the mark" shot. That would allow the same relationship of a "lower back to lower head" and "higher back to higher head" shot. A great reason for Gerald Ford to move the lower back location as he did. And, since CE884 uses a back height wound (3.27ft above the street) instead of a true z313 head shot elevation, one might get confused as to the actual true ballistics and where that shot actually occurred on Elm Street. But, leave it to the powers that be to convince you a 10" vertical drop on Elm Street equated to a .9ft distance traveled(z161-166) instead of 15.25ft (10"/12 =.8333 x 18.3)

Doug Horne excerpt: "...1) those altering the Zapruder film at “Hawkeyeworks” on Sunday, November 24, 1963 were extremely pressed for time, and could only do “so much” in the twelve-to-fourteen hour period available to them; (2) the technology available with which to alter films in 1963 (both the traveling matte, and aerial imaging) had limitations—there was no digital CGI technology at that time—and therefore, I believe the forgers were limited to basic capabilities like blacking out the exit wound in the right-rear of JFK’s head; painting a false exit wound on JFK’s head on the top and right side of his skull (both of these seem to have been accomplished through “aerial imaging”—that is, animation cells overlaid “in space” on top of the projected images of the frames being altered, using a customized optical printer with an animation stand, and a process camera to re-photograph each self-matting, altered frame);" Something like this. Quite distinct, just as the extant frame is.

Two Head Shots and the Zapruder Film
Chris Davidson replied to Roger Odisio's topic in JFK Assassination Debate
Would love to have viewed those still photos: -
Moving Connally leftward, I believe Knott's Lab was trying to show something like this alignment. So why not use what the WC provides. JBC was approx 1" lower in height (WC testimony) sitting in the limo, than JFK was. Use your imagination for the downward path. Much more faith in Dr. Shaw than the WC.

Those pesky boxes. The man in the gif is placing a pylon at would equate to the limo front at extant z235. This would put JFK's physical position in the limo 15.1ft back from there. If you care to look at CE884 entry for z235, it will show you a station # of 396.8 15.1 ft back from 396.8 = 381.7 The WC determined the SBT occurred at station # 381.3 = 4/10ft difference in placement. Robert Shaw said No No, there was a Connally shot at approx extant z235/236 according to his viewing of the extant zfilm and his experience with bullet trajectories through the body. But, from the west end of the TSBD. The final WC method was to survey JFK's actual physical location in CE884. Do you understand how using the limo front and JFK's physical location in the limo would confuse the truth as to not enough time in between for those shots? PS. The WC also documented a shot that was at approx extant z203.

Take the same 33 frame gif above and apply a frame removal sequence to end up at 14 frames again, below. Note the difference in movement between foreground/background between the two gifs. Now take a look at a completely different extant z version and compare that same foreground/background relationship to the two gifs.

I think this is the John Orr project
Chris Davidson replied to James DiEugenio's topic in JFK Assassination Debate
I wonder how the WC went about adjusting for the alignment problem.(see page bottom) Why don't we just vary the limo's path from where the professional surveyor had plotted JFK every 25ft. Credit to Tom purvis: -
Not sure when Keyvan's frame was created. In Final Cut Pro you can create new(in-between) frames using "Optical Flow". The example I'm providing is an "interlaced" frame on the left side(notice the horizontal lines through Jackie's face). The right side is the same frame(using Photoshop) with a gaussian blur of 2 pixels, followed by an unsharp masking with an amount of 500 and radius of 1.

The Finding of the Sniper's Nest
Chris Davidson replied to Alan Ford's topic in JFK Assassination Debate
The Warren Commission created their own false evidence. Start with CE884 and JFK's head height at extant z313. -
Agree completely.
-
I don't see any movement on his part. Maybe a slight torso twist to the east bringing that side out of the shadow? Hard to tell. Jones bending over, a lot easier to see.
-
Obviously later than Wiegman. First few frames have a shadow, not covering as much of Lovelady? as we see in Wiegman. Large gif is approx. five frames apart. As the cameraperson moves slowly past the steps, the shadow disappears. It's the same man in Willis.

Speaking of comparisons: -
The Altgen's Metamorphosis
Chris Davidson replied to Chris Davidson's topic in JFK Assassination Debate
Clean lines can be another problem for "touch up" artists. In fact, just look for someone within the same photo to use for a comparison. Besides the impossible shoulder dilemma appearing, you can decide what that (red arrow) area is. -
The Altgen's Metamorphosis
Chris Davidson replied to Chris Davidson's topic in JFK Assassination Debate
From the crossing elbow "touch up", follow the arm that runs back through the top half of the shadowed face and into Lovelady's head. Note the indention in Lovelady's head where they meet. -
The Altgen's Metamorphosis
Chris Davidson replied to Chris Davidson's topic in JFK Assassination Debate
Next up: Straight down(at the photos bottom) under the "dso" in Davidson is the mask for the woman who is shading her eyes with her right arm/hand. See previous gif.
