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

Here is another image of the Shooter wearing his hat. It's from one of the films. Notice that the ribbon is straight black.

So, what reason is there to accept this as authentic photography?

There is no reason to accept it. And, when we look at it in the KRLD film, no camera flashes go off at the time of this. We don't see the sign of any flash. Check it yourself. Start at 13 minutes.

And there, of course, his hat ribbon is uniformly black, as you can see below. 

The idea that his black ribbon-piece would be captured grey by Jackson's camera is preposterous. I mentioned that my enemies should take out a camera and do some experimenting. See if they can duplicate the conditions, including the lighting conditions, and see if they can make the black strip appear grey, and just as chiseled as we see in the Jackson photo. Well, they are not going to do it. But, who is to say that I won't do it? And what do you think is going to happen? What result do you think I am going to get? Do you think the black vertical strip is going to come out grey for me? You know darn well it isn't.
