Der Kodak-Spezialist Roland Zavada, der den Film untersuchte, erklärte jedoch, an ihm seien keine Veränderungen vorgenommen worden.

Doug Horne hatte Gelegenheit mit Roland Zavada ins Gespräch zu kommen.
Hier ein Auszug, dass selbst Zavada der Meinung ist das der Hinterkopfbereich wie ein "Patch" bei Frame 317 aussieht, er aber nicht von einer Manipulation des Z-Films ausgeht, da er nicht weiß, wie das gemacht wurden sein soll.
Das er nicht weiß wie es gemacht wurden sein soll, heißt aber noch lange nicht, dass es zu keiner Manipulation des Z-Films gekommen sein kann.
Zavada ist damit keine eindeutige Quelle, um den Z-Film definitiv als das unverfälschte "Kameraoriginal" ausweisen zu können.
Frame 317:
gezoomt:
In a small breakout session for Q & A after the main event, Rollie admitted to his own preconceived bias that the film was authentic, when he began his investigation for the ARRB; he then said, in so many words, and implied with his tone, that he was proud of it!
In the breakout session, when Josiah Thompson asked him to display the controversial frame 317 and comment on whether the black object covering the rear of JFK's head was a natural shadow or evidence of alteration, Rollie put up the slide (a very dark, muddy image of 317 with much contrast present---an image greatly inferior to the Hollywood scans of the forensic copy), and then said words to the effect:
Zavada´s Statement zu Frame 317:
"It certainly looks like a patch; it looks like it could be an alteration. But I haven't seen evidence of how it was done, so I refuse to believe it."
[This is very close to a verbatim quote---guaranteed to be accurate in its substance.]
I and several others, including Leo Zahn of Hollywood, then suggested---demanded, actually---that Rollie display ALL of frame 317---not just the portion showing JFK's head. When this slide was finally displayed, I asked everyone present in the room what explanation those who were against alteration had for the extreme difference in density between the shadow on Governor Connally's head, and the extremely dense and dark (almost D-max) "anomaly" on JFK's head in that same frame. The two so-called "shadows" have absolutely no relation or similarity to each other, yet both men were photographed in the same frame, at the same instant in time, on the same planet, with the same light source (i.e., the sun). The ensuing silence was more profound than that inside the whale that swallowed Jonah. Rollie and Tink had no explanation for this. Nor does anyone else, who believes that the Zapruder film is an unaltered film. The most reasonable, and currently the only known explanation for this paradox in frame 317, is alteration---the blacking out of the true exit wound on the back of JFK's head in that frame, and in many others, with crude animation.
