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

No, Backes. I was only trying to determine how a motorcyclist who was entering the visual field of the camera from east to west would be captured in the photo, what would appear first how it would progress. Getting the general setup and arrangement was all I had to do. Duplicating it exactly to the square inch wasn't required, and it was hardly possible. Obviously, I didn't have the same motorcycle. And, there was guesswork involved. But overall, my capture of the field of the Moorman photo was fine. It was more than adequate. 

 The very biggest issue was not Mary's exactly location east to west or even north to south.  The very biggest issue was the angle of her turning (that's theoretical because she didn't turn at all). But, it doesn't matter because the results were so polar, so extreme that it would only have varied slightly if the position was more precise. 

That's a night and day difference, Backes. Nobody who goes to Dealey Plaza to do their own recreation is going to capture a lone, long right arm like we see on the right.
