It is also revealing that the PEP did not do any measurements on 133-C to determine if there were any differences in the distances between the background objects in 133-C and those in 133-A and 133-B. They only provided measurements for 133-A and 133-B.

If the PEP did do parallax measurements on 133-C, they did not mention doing them and did not publish them. The odds that the camera would have returned to virtually the same horizontal, vertical, and angular position twice are so fantastically remote as to be effectively zero.

How could the PEP pretend to be proving that the backgrounds in the photos were not the same when they only did parallax measurements on two of the three photos?

133-C shows the backyard figure in a different pose than his pose in 133-A and 133-B. In 133-C, he is holding the rifle at a different angle and is holding the newspapers in a different position than in the two other photos. 133-C also shows him in a different position in relation to the bush on his left than his position in 133-A and 133-B. All of these changes would surely suggest a change in the camera's angular, horizontal, and vertical position. One would therefore think the PEP would have been anxious to do parallax measurements on 133-C and contrast them with the measurements for 133-A and 133-B--unless, of course, the measurements proved to be problematic and either indicated even smaller camera movement or no camera movement.
The proposition, "A, B, and C are identical" can be disproved by demonstrating that any two items are not identical. That's all they needed to do.

Below are some of the problems with the backyard rifle photos noted by Hershal Womack, a professor of photography at Texas Tech University:

If Lee Harvey Oswald cocked the shutter each time for Marina as she supposedly stated, then how did Oswald's leg stay in the same place relative to the dark area next to his left, photo right knee? Compare in two of the three photos. Measure from the line on the building on the right and measure to different parts of his body and I think you will reach the same conclusion. Note the Roscoe White backyard photo.

Other measurements from a fixed object like the stair post to portions of his body or even the pistol appear to be the same or near so. There's no way you could move and go back to the identical spot and take the same position without drawing the image on the back of the camera.
With this in mind then how did he get taller if neither he nor the camera moved. Maybe the camera was on a tripod and lowered which would make him taller but it would do the same to the post which may be a little taller but the height of Oswald seems out of proportion to that of the post or vice-versa.

Mytton's discrediting doubling down on his claims about the differences in the distances between background objects and their implications deserves further comment:

Quote
Again, there are no "microscopic" distances.

Yes, there most certainly are. Let us once again look at the table for paragraph 441 regarding the horizontal parallax measurements in the PEP's report (6 HSCA 178). The difference in the lower-level "a" distance between 133-A and 133-B was measured to be just 0.8 mm, or 0.03 inches, or 3/100ths of an inch. The difference in the middle-level "a" distance was found to be just 0.1 mm, or 0.003 inches, or 3/1000ths of an inch. The difference in the upper-level "a" distance was found to be just 1.1 mm/0.04 inches or 1/25th of an inch.

The difference in the upper-level "a" distance was the largest of the differences in the horizontal parallax measurements. The naked eye cannot a detect a difference of 1.1 mm/0.04 inches in the distances between background objects in the photos, unless they have super-human vision. To detect a difference of just 1/25th of an inch in the distances between the same objects in two photos, a person would need the aid of a high-powered magnifying glass or a microscope, just as the PEP did.

Let's continue: The difference in the lower-level "b" distance between 133-A and 133-B was found to be just 0.5 mm, or 0.019 inches, or 19/1000ths of an inch. The difference in the middle-level "b" distance was found to be 0.7 mm, or 0.027 inches, or 27/1000ths of an inch.

The parallax as determined from measuring the enlargements of CE133A/B corresponds to a significantly larger distance in the real world.

If this were true, the horizontal and vertical changes in the camera's position would not have been "slight" and "very small." You seem to keep forgetting that the PEP could only determine camera movement by ratioing the parallax measurements, and that those incidents of parallax were so tiny that they were expressed in millimeters and were only detected with the aid of computer analysis and microscopes.

Quote
Further, this larger distance is not the actual distance the camera would have moved.


But if the differences in the background-object distances had actually been larger "in the real world," this would have proved the camera's movement was larger "in the real world," a point that the PEP would have loudly trumpeted.

The PEP produced screen-size enlargements of the photos as visual aids for their testimony to the Select Committee. Not once did Kirk and McCamy refer to a difference in background-object distances that could be seen with the naked by the committee members.

Quote
This distance [of camera movement] would be expected to be somewhat larger than the parallax.

Huh? Again, the PEP admitted that the changes in the camera's horizontal and vertical position between exposures were "slight" and "very small." Furthermore, the PEP did not even measure for changes in the camera's angular position, implying the impossible scenario that the camera did not tilt in the slightest degree at any angle between exposures.

And please tell me how the PEP could prove that the same background was not used in the backyard photos when they only did parallax measurements on two of the three photos, especially given the fact that the backyard figure's pose in 133-C is different than his poses in the two other photos. I can't help but suspect that the PEP did measure for parallax in 133-C, realized the measurements and resulting camera movement were problematic, and decided to simply ignore 133-C when it came to parallax and camera movement.

Quote
Also, since Marina would have held the camera at about the same height for each exposure, we wouldn't expect to see a lot of vertical parallax anyway.

This is just silly, given the difficulty that the PEP had in detecting any change in the camera's vertical position. They could only find one determination for vertical parallax and had to resort to claiming that vertical parallax was established because the small black rectangle on the bottom edge of a part of the fence appears more elongated in the vertical direction in 133-A than it does in 133-B (6 HSCA 179).

Moreover, in her later years, no longer under threat of deportation, Marina stated in a taped interview that she did not take the backyard rifle photos in evidence.

Years earlier, when she was still claiming she'd taken the pictures, she said she held the camera up to her eye to take the photos. Humm, no way. The Imperial Reflex 620 had no viewfinder that you could hold up to your eye--it only had a waist-level viewfinder on its top, which required you to hold the camera below the level of your head and to look down into the viewfinder.

As I've said before, if you want to prove the backyard photos are authentic/pristine, conduct a reenactment with people who don't know what they're reenacting. Have them use an Imperial Reflex 620 camera and take three photos in the manner alleged for the backyard photos, and see if their photos contain the same tiny differences in the distances between background objects and if their photos exhibit only "slight" and "very small" horizontal and vertical camera movement between exposures.

And while you're at it, do parallax measurements to determine if there was any change in the camera's angular position between exposures. Unless the participants miraculously manage to avoid tilting the camera even in the slightest degree, you will find that the camera's angular position changed between exposures.

Uhh, no... YOU conduct the reenactment. YOU do the measurements. It's not the responsibility of other people to validate your long-debunked blathering about these photos, which have been proven authentic time and time again.
