Worse yet, Griffith cites Jack White as *his* photographic expert:

Mr. GOLDSMITH. Have you ever examined the original exhibits? By that I mean the original first generation of prints of 133-A and B and the original negative?
Mr. WHITE. No. I have only seen the DeMohrenschildt picture in the original.
Mr. GOLDSMITH. So as to exhibits 133-A and B you have never examined the first-generation print and you have never examined the original negative; is that correct?
Mr. WHITE. That is true. I have only the prints that were furnished me by the National Archives.
Mr. GOLDSMITH. Do you know what generation prints they were? By that I mean if someone were to take a picture of 133-A or B, that would now be a second-generation print?
Mr. WHITE. That is right.
Mr. GOLDSMITH. And if someone were to take a picture of that, it would be a third-generation print and so on?
Mr. WHITE. True.
Mr. GOLDSMITH. The materials you were given, do you know what generation they were?
Mr. WHITE. I have no way of knowing. I would presume that they were the next generation after what the exhibit is in the National Archives. That is just a presumption. I have no way of knowing.
…
Mr. GOLDSMITH. Have you had any training in analytical photogrammetry?
Mr. WHITE. No.
Mr. GOLDSMITH. Have you had any formal training in forensic photography?
Mr. WHITE. No.
Mr. GOLDSMITH. Have you had any formal training in the study of shadows in photographs?
Mr. WHITE. No.
Mr. GOLDSMITH. Mr. White, if the picture is authentic, would you expect all the shadows cast by objects in that picture to line up parallel to each other?
Mr. WHITE. I am no expert on that. 1 wouldn't have any conclusion unless you pointed some specific reference to me.
Mr. GOLDSMITH. Are you familiar with the concept known as "vanishing point"?
Mr. WHITE. Oh, yes.
Mr. GOLDSMITH. When you studied these photographs did you use the vanishing point concept to analyze the shadows?
Mr. WHITE. Not as such. I didn't see any point in using a vanishing point to analyze shadows.
…
Mr. GOLDSMITH. Mr. White, you have made reference to several points in these photographs that suggest that Oswald's head is disproportionately---- I withdraw the question. That the body of Oswald is not consistent in the various photo-graphs in light of the head size; is that correct?
Mr. WHITE. Yes.
Mr. GOLDSMITH. To what extent, if any, did you compute photogrammetrically the effect of an object's tilt on its apparent length in the photograph?
Mr. WHITE. As I said, I am not a scientist. I don't indulge in that sort of thing.
Mr. GOLDSMITH. Mr. White, I realize you are not a scientist. Do you now whether scientists consider the use of transparency overlays to be a good way of detecting differences between soft edged images?
Mr. WHITE. I have no way of knowing that.
…
Mr. GENZMAN. Would you briefly describe the exhibit labeled F-396?
Mr. WHITE. OK. Once I received this photo of the Archive rifle and studied it in connection with some of the others, I had what you might call a brainstorm, after hearing some rifle experts talk. When I appeared before Senator Schweiker and the Church committee, I talked to some rifle experts. They said frequently when somebody buys an old war surplus weapon like this, the first thing he does is modify the stock to fit his physique. Therefore the thought dawned on me that the wooden stock is changeable.
Mr. GENZMAN. Did you line up the metal parts?
Mr. WHITE. Yes. I made prints where the metal parts of the rifle, that is, from the muzzle to the trigger guard, were all identical lengths.
Mr. GENZMAN. After lining up the metal parts, what did you determine about these stocks?
Mr. WHITE. I determined that the butts were different lengths after lining up the metal parts.
Mr. GENZMAN. Does the photograph at the bottom demonstrate this discrepancy in the length of the stocks?
Mr. WHITE. Yes. Here we have the Archive rifle printed in brown, the Warren report rifle printed in red; all the way from the muzzle through all the metal parts, in fact all the way to the comb, which is this little notch in the stock of rifle. All of that matches exactly. Only from here back, less than one-fifth length of the rifle, does not match.
Mr. GENZMAN. Briefly what did you determine from your study?
Mr. WHITE. It is my opinion that we have been shown by the authorities more than one gun as being the assassination weapon.
Mr. GENZMAN. Thank you, Mr. White. Mr. Chairman, I have no further questions.
Chairman STOKES. Mr. Goldsmith?
Mr. GOLDSMITH. Mr. White, I just have one question.
Mr. WHITE. All right.
Mr. GOLDSMITH. When you did this study, did you compute photogrammetrically the effect of tilt on the way that the length of an object appears in a photograph?
Mr. WHITE. I conducted a study by photographing a yardstick from three different-
Mr. GOLDSMITH. Mr. White, answer my question. Did you compute photogrammetrically----
Mr. WHITE. What is "photogrammetrically"? Describe to me what "photogrammetrically" is.
Mr. GOLDSMITH. I just have one more question Mr. White. Do you know what photogrammetry is?
Mr. WHITE. No.

White didn't even know how to take perspective into account when he reached this conclusion:
