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

Robin Unger is changing his story about when the Moorman photo was taken as per Nix. Now, he wants to go with this frame.

So, this is supposedly one frame before the other one. So, in one frame, BJ Martin's head went from being obscured to being visible.  

But, since Mary doesn't have her arms raised, how could she be taking a picture? 

You see her head, right? Do you see a camera in front of her face? Do you see her arms raised and holding a camera? Do you see a camera?

You want that I go in closer? Alright, we'll go closer.

You see her head rising above her shoulders, right? Do you see any camera in front of her face? Do you see her arms going up to hold the camera? Do you see a camera? 

So, why do you claim that Mary was taking a picture at that moment when she was obviously doing no such thing?

Besides, we have a much better image from Gerda:

This would be a few frames later, but Mary Moorman was not taking a picture at this time. She did not have her camera raised. And she wasn't even looking in that direction. She appears to be facing straight ahead and not turned towards the limo at all. 

Your claim to have found the Nix frame which corresponds to the Moorman photo is completely wrong, groundless, and impossible.
