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

We know that whomever took the Moorman photo was using a camera with a wide angle of view because of all that was captured in the picture, from east to west. If you consider the distance between Newman and the men on the steps, it's quite a distance captured, and therefore, a wide angle of view. 

So, with such a wide angle of view, as BJ Martin entered her field of view from the east, it was his whole form that began to be captured. It didn't necessarily have to include all of him because the back of him could be outside the camera's field. But, it was his entire form that was entering her viewing field, and it was his entire form that would be captured. In other words, the angle fanned out from the camera such that the viewing field was much bigger than he was. He might not enter it completely, but however much he entered it, the entirety of that percentage of him would be captured in the image. 

And in particular, the left side of him, which was facing the camera, would definitely be seen and captured by the camera, while the right side of him might be obscured by the left side, and especially when it came to his right arm since it was, by necessity, cast at the same level as his left because of the design of the motorcycle. 

Above, we cannot see his right hand. We see much of his right forearm, but just a little of his right upper arm and none of his right shoulder. However, his left hand and forearm and upper arm and shoulder, we see in their entirety. That was essentially the same situation for the taker of the Moorman photo. Therefore, this supposed capture of the right arm only by Mary Moorman is, by scientific necessity, false. 

There is no way that can be real. That right arm in the lower right corner is fraudulent. It is art, and it is evil art at that. It proves that the Moorman photo was altered. And it was just one of many alterations that were done to it.
