Oh My! David Von Pein, That is as rich as it gets!
And, to be sure that we preserve David Von Pein’s entire cart-load, here is his full quote:
Okay, she might have tilted the camera 90 degrees. Again---no big deal. (It's only a "big deal" to conspiracy theorists who are bent on finding "conspiracy" around every corner and in every Neely Street backyard.)
The long and short of it is ----
Seeing as how Marina didn't know the first thing about how to take a picture with Lee's Imperial Reflex camera, she did whatever Lee told her to do in order to get the pictures to come out correctly. And when she was asked to recall the specific details of how she held the camera and how many photos she took, she just flat-out forgot. Yes, she did remember some of the details about the Backyard Photos session---such as the detail about how silly and "crazy" she thought Lee looked that day in his all-black outfit with his guns....
"I asked him then why he had dressed himself up like that, with the rifle and the pistol, and I thought that he had gone crazy, and he said he wanted to send that to a newspaper."
....But the details of how the camera worked and the exact number of pictures she took were things that obviously were not important enough to her at the time for her to make a mental note of such trivial things. And so, almost a year later when she was asked to recall such things, she was not able to do so. That's certainly not an unheard-of situation at all, IMO.
