Yes, I was replying to your previous post.
There were two studies done in 2009 and 2010 that still left questions about the lighting and the shadow that could have been manipulated on Oswald's photos. The last study was done by Dartmouth about 5 years ago that addressed those issues and concerns. They used 3D model computer graphics to determine that there was no manipulation in the photos and that Oswald's awkward pose was indeed authentic. The final verdict refutes the idea that there was any manipulation or the photos were phony to begin with. That's the evidence that came from a respectable University that performed an unbiased study of the evidence. I'm just putting it out there what was determined through photo and 3D model analysis. People can choose whether to believe it or not. But that is what was determined through forensic photo analysis.
Dartmouth probably had a respectable team of forensic photo analysts looking at the photo(s), however, being a photogrammetrist myself, I know the limitations they faced with 3D modelling. The algorithms can only detect a sloppy job and can only identify content that doesn't fit the model. But they can't detect any superimpositions if the scaling, color, composition and resolution are accurate. The absence of mistakes doesn't make it authentic. So take Dartmouth's analysis with a grain of salt because they were only looking for obvious signs of editing. Not a useless analysis, but inconclusive at best, otherwise, incomplete. You need the negatives to authenticate anything. And even then.
That said, I buy their conclusions that the photos weren't edited because they didn't need to be. People assume they were edited because of the gross differences between 133a and 133b. Oswald's head becomes enormous and in focus. Dartmouth must have concluded that Oswald's head was outside the "sweet spot" of the lens for all shots except for 133a, which accounted for the distortion. What they should have done was compare the spherical aberration for all the photos and look for anomalies. It would soon become apparent that 133a stands out like a sore thumb and does not match the others. Why didn't Dartmouth investigate whether all the photos where shot with the same camera/lens and analyse the negative for 133a? Oh, right, the DPD (cough, cough) lost it along with all the others. If the BYPs don't represent a smoking gun implicating the DPD in the Big Event, then I'll eat a bug.
