The HSCA Photographic Panel studied CE-133A, CE-133B, the negative of CE-133B and Oswald's camera (among many other items related to the photos, such as first generation prints of CE-133C).

The panel first performed a visual inspection of the photos, by use magnifiers and microscopes.  During this inspection, the panel made enlargements of the photos using various exposures and ranges of contrast.  These enlargements produced prints which ranged from very light to very dark.  In the darkest parts of the photos, the detail could be seen best in the lighter prints.  In the lightest parts of the photos, the detail could be seen best in the darker prints.  The panel felt this was the best opportunity of detecting any evidence of falsification anywhere in the pictures.

The panel also used digital image processing to determine if there were any unnatural edge lines or differences in grain structure or contrast.

Both photos (CE-133a and CE-133B) were also studied by the panel using stereoscopic techniques, which allowed the panel to see the photos in 3-D.  This method will detect forgeries in prints because it produces a photographic copy of a photograph.
 When viewed in stereo, these copies will not project a three-dimensional image unless made from different viewpoints along the same axis.  Retouching of the original photo can be detected when two photos depicting the same scene are viewed in stereo, the retouched print will not be on the same plane in which it should be lying; the items seen in the photo will be either in front of the plane or behind the plane.  Because of this, when viewed stereoscopically, fakery can easily be detected.

One final method the panel used to examine the photos was photogrammetrically.

Using all of these methods, the HSCA Photographic Panel detected no signs of forgery.

Thanks for that Bill.  Martin, a layman?s response.

So they confirmed that the photos weren?t altered but they could not confirm that the photos weren?t staged or JFK?s corpse altered. Correct?

I?m agnostic on the body alteration theories. I accept the expert opinions that the photos haven?t been altered but also think people who were present at the autopsy who cast doubt on the photos shouldn?t be ignored.

Shouldn?t be ignored? Medical and ballistic evidence trumps witnesses every time.  What do you suggest be done with them?

Shoot.  I think I wasn't paying close enough attention.  I was referring to the study on the backyard photos, not the autopsy photos.

As for the autopsy photos and X-rays, in 1967 the autopsy pathologists (Humes, Boswell, and Finck), the acting chief of radiology (Ebersole) and one of the autopsy photographers (Stringer) viewed the autopsy photographs and/or X-rays and confirmed the photos and X-rays were accurate in the portrayal of the wounds of the President.

The Medical evidence in the Kennedy assassination is a mess.

What Ballistics evidence are you referring to?

Take your pick. The ordering of the weapon. Possession of the weapon as determined by b/y photos. That M/C to the exclusion of any other weapon fired the bullets. Oswald?s finger print on the trigger housing.  No evidence of other weapons bullets hit Kennedy. LHO shirt fibers found in the butt plate. If this weapon didn?t kill JFK, then JFK is still alive.

The HSCA's Photographic Panel studied the autopsy photos and X-rays.

From the Kennedy Library in Massachusetts, the panel gathered X-rays of the President which were made when he was alive.
 In examining these X-rays, they studied unique anatomic characteristics (of the turcica, cranial sutures, vascular grooves, air cells of the mastoid bone).  A difference in any of these anatomic characteristics among the autopsy X-rays would show that the two sets of X-rays were NOT of the same person.  Similarities of these anatomical features among the autopsy X-rays led the panel to conclude that the autopsy X-rays were of same individual as the X-rays that came from the Kennedy Library (again, made when Kennedy was alive).

Dr. Lowell Levine, a forensic odontologist and an expert in dental comparison, testified before the HSCA in 1978.  He was experienced in the dental identification of people who died of some sort of unnatural death (such as airplane crashes, etc.). Levine compared the X-rays from the Kennedy Library with the autopsy X-rays. He concluded that the three autopsy skull X-rays are identifiable as being of the same person as the dental X-rays of President Kennedy.
