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

It's noteworthy that in this Muchmore frame, which shows most of the length of the limo, we definitely get the sense that the front of the car is lower than the back of the car, that it is going downhill.

Likewise, the motorcycles seem to be going downhill. But, in the Moorman photo, the front of the car is just a little bit higher.

What is the reason for that? Why would Mary Moorman's photo turn out like that? 

This plat shows the positions of Moorman, BL, Bell, and Muchmore.

You can see that Bell was very similar to Moorman in terms of his trajectory. Of course, with his camera, he was shooting all over. But when he was shooting directly across Elm, it would have been close to the same trajectory as Mary Moorman. And his frame shooting across the street looked like this.

Notice first that you do see the slope in the road and the front of the cars being lower in front. Take note again of his location in relation to Mary Moorman. It's pretty close to the same view. 

When we compare that Bell frame to the Moorman photo, we see that there is a little more captured on the right in the Moorman photo and a little more captured on the left in the Bell frame. 

Bell was shooting with a film camera from much farther back, so it's expected that he would capture more. But, the point is that the above frame was about the same as what Mary would have gotten, except Bell was farther back. Why wouldn't Mary pick up the slope?
