My snail mail March 2010 Popular Mechanics magazine showed up here this
morning.On page 14, Solo Act, it says,,,

New Forensic Analysis Shoots A Hole In A Kennedy Assassination Theory.By
Alex Hutchinson.
Digital forensic tools have added to the evidence that Lee Harvey Oswald
was a lone gunner rather than part of a conspiracy to kill President
John F. Kennedy.Hany Farid, director of the Neukom Institute for
Computational Science at Dartmouth College, analyzed a famous photo of
Oswald that some say must have been doctored, because the shadows under
Oswald's nose and behind his body appear to be caused by different light
sources.However, Farid found no sign of tampering when he measured for
inconsistencies in the image's underlying pixels.He also created a 3D
image of Oswald that demonstrated that both shadows could have been made
by the sun at the time Oswald's wife took the photo.Farid says that the
image would be hard to fake today, and likely impossible using 1963
technology.

And I SAY, Hany Farid is FULL of SH.T!!! Photo film negatives are Easy
to fake.
