And it reveals another staggering incongruity in the Moorman photo. Look at the angle that the arms are supposed to be for those Dallas PD motorcycle cops.
The same was true of Glenn McBride, Mary's friend.
Let's compare the two:On the left, it's like the image was stretched like a rubber band, and the arm is not rising steeply enough.
But, in bpete's case, there was hardly any steepness at all. The arms were sloped very little, and they come across as practically horizontal, especially the left one.
The reason why it's important is because the process of capturing an image of the right arm alone involves cropping the left arm out. You can do it by actually cropping, as I did, or you can do it using the zoom function of the camera, which is a form of cropping. Mary's camera didn't even have a zoom function.
But, the only way to do it is to somehow raise the bottom of the picture so that it falls between the two arms. Besides zooming in, it also helps a lot if you physically raise your camera up, if you elevate it in the air. And that's why I asked bpete at what height the pictures were taken.
So, through a combination of zooming-in and also raising the camera, you can get it to where the horizontal bottom of the camera falls between the two arms, and wahlah, you can take a picture of just one arm. But, the only chance of doing that is if the arms are close to horizontal. If the arms are inclined steeply, it doesn't work because as you come up, as you lift the bottom of the picture, you've still got some arm there that you don't want. Look at Glenn McBride again:
There's no way you could crop out his left arm by raising the bottom of the picture because there would still be some left arm showing. So, if you were on his left side (Mary's side) shooting at him, you could never raise the camera high enough to elude his left arm because his left arm is rising with you. You really need a picture like this:
Notice that this image is really ideal for the task at hand because there is very little left arm in it to get rid of. Just the hand, wrist, and a little bit of the forearm. There's much more of the right arm showing, in fact, there is more of it showing there than there is in the Moorman photo. But there is very little elevation between his left hand and his left forearm, what little there is, all bpete had to do was get above it. And there is a huge gap between those two relatively horizontal arms. In a word, it's perfect, and it's really like stacking the deck in poker.
Notice something else: this image was taken from a slightly leftward angle, and that's why the right side view mirror is obscured behind the windshield. The alternate picture was taken from a slightly rightward angle, which put the right side view mirror in view.
Similarly, in the above picture, the top of the windshield is in line with the center of the little house. But, in the picture with both arms, the windshield goes slightly beyond the edge of the little house.
That is a significant difference, and it shows you that the photographer moved. So, this was not a situation in which the pictures are the same except for the amount of zoom. And keep in mind that both pictures are zoomed because without any zoom at all from six feet away, you'd capture the whole bike. But, the photographer didn't just zoom; he moved. He moved the camera, and he relocated himself.
Ultimately, this comes down to cropping: using the zoom function of the camera as a way to crop the picture. But, that, by itself, wasn't enough because he had to have an image that was cropable.
What relevance this has to the Moorman photo is zero. Mary Moorman, from her side of the street, could not possibly have caught just a partial right arm of BJ Martin and nothing else.
It is utterly and completely impossible.
