Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

So, Hargis and Martin were captured in the Moorman photo close to how they look in this Muchmore frame.

That Martin's head that is left of Hargis' head, but only in the picture. In reality, Hargis was forward of Martin, and by quite a ways. It looks the way it does here because it was taken from the perspective of Marie Muchmore, whose perspective was similar to Babushka Lady's. But, Mary Moorman's perspective can be described in one word: perpendicular. And when your perspective is perpendicular, your perspective is neutral. You are not getting any misleading angular effect. And that means that Mary Moorman was seeing the scene as it was, with Hargis in the lead over Martin.

And that's exactly why they had to change it because no doubt in Mary's actual photo, Hargis was ahead of Martin. It would have been if she had taken it right there. But, I believe she had taken it a few frames before. This would be my best guess for when Mary took her picture:

  
Presumably, Mary would not keep her camera up to her eye after she took her picture. She would have no reason to. She has her camera up to her eye here, and it is the last frame in which she does so, and therefore, that must be when she took her picture. But, Mary was perpendicular, so she saw Hargis ahead of Martin. That is what her picture must have showed. So, when they went about converting Babushka Lady's photo to Mary's, they compared them; they saw the angularity in Babushka Lady's and the effect that it had in displaying Martin ahead of Hargis, and they knew they had to get rid of that if they were going to pass it off as Mary's photo. And so they did. That is where the thumbprint came in. They did a lot of altering in that area. The feature of Martin's right arm grasping the handle of his motorcycle is pure art, and so is the area behind Chaney on the other side with its vague, light renderings. It's art.

Where's the tool box behind Chaney's bike on the far side? Oops, they forgot about that. His motorcycle looks more like a riding lawnmower.

Of course, they also doctored Kennedy's head to restore its intactness after the fatal head shot which preceded the photo. And those are the major alterations in the Moorman photo, though there are probably more.

And all of them follow from the simple fact that right arm of BJ Martin seen in the Moorman photo is fake. The human body is not transparent, and the left side of his body had to be captured because of the simple fact that it was there. The camera doesn't skip anything. It captures everything in its field of view- unless an object is being obscured by another object in that field. But, in this case, nothing was obscuring the left side of his body to the camera. The camera had to see it and had to capture it.
