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

This was a very valuable outcome from the Altgens recreation. It shows the impossibility of the Black Hole Man's face being reduced to total blackness. The photo on the right was taken with Tri-X film from Altgens' position on lower Elm. It's quite true that the subject should have been turned to his right so that he was facing the camera. However, we can extrapolate that if he was, his face would have been just as visible and illuminated as it is. So, it really doesn't matter. And, it is the exact result that we would expect because there are lot of photos of people visoring their eyes with their hands. And, in no instances, does the entire face get blackened out. As far as I know, the Altgens photo is unique in the world of photography in manifesting such an effect. And note that never have any of my opponents provided a comparable image to what we see in the Altgens photo- a headless man. 

And the irony is that the man is standing in the bright sunlight. We know that light had to be reaching his eyes because that's the reason he was visoring. Why else would he do it? And you can see how well-illuminated his arms and hand and shirt are. He was standing in the bright sun. And his hands are way too small to blacken out his whole face in deep, dark shadow. And notice how far out his elbows are. As the saying goes, you could drive a truck through there. So, his arms are not blocking the light from reaching his face.  
Black Hole Man is a physical and photographic impossibility. There is no way that that is the unaltered product of Altgens' camera and film. The laws of physics weren't suspended in Dealey Plaza on November 22, 1963. So, that was the result of something that was done to the film after it was taken. In a word, it was an alteration.
