Mr. EISENBERG. I say, there is an apparent match in photographs, in
color, or is that just my eyes deceiving me?
Mr. STOMBAUGH. This one appears to be slightly lighter than this shade.
Mr. EISENBERG. I see.
Mr. STOMBAUGH. But actually they are both a gray black, almost black in
color.
Mr. EISENBERG. But under the microscope they were identical, and a
different shade than what we see in Exhibit 675?
Mr. STOMBAUGH. That is correct.
Mr. EISENBERG. In all these cases did you make your determination of
color and match under the microscope, or by use of the photographs?
Mr. STOMBAUGH. Under the microscope.
Mr. EISENBERG. And these are illustrative and prepared for the
Commission's use?
Mr. STOMBAUGH. Yes, sir.
Mr. EISENBERG. Now, you have a chart of photomicrograph captioned
"Match Between Dark Blue Cotton Fibers From Butt Plate of Assassination
Rifle, etc." Did you prepare these photographs or were they prepared
under your supervision?
Mr. STOMBAUGH. Under my supervision.
Mr. EISENBERG. May I have these received as Exhibit 676?
Mr. DULLES. 676.
(The item referred to was marked Commission Exhibit No. 676, and was
received in evidence.)
Mr. EISENBERG. What is the magnification of 675 and 676, by the way?
Mr. STOMBAUGH. All of these were made at approximately 400 diameters.
Mr. EISENBERG. Did you find a color match here?
Mr. STOMBAUGH. Yes; the color match of the dark blue cotton fibers
shows rather well in this photograph, Exhibit 676.
Mr. EISENBERG. Now there is also a violet-colored fiber running through
the right-hand side of 676.
Mr. STOMBAUGH. Yes, sir; I asked the photographer about this when he
developed this and I said, "Why did we get this, this is not in the
slide at all," and he said that is one of the orange fibers. They use
different techniques in bringing out the blue and the yellow-orange in
a photomicrograph.
Mr. DULLES. The shades are the fiber of the blanket?
Mr. STOMBAUGH. No; this shade in the photograph is different from what
that fiber actually is. It is in the development process. I am not too
familiar with color photography. There is an art to it. However, I do
know that there are times and technical limitations on the accuracy of
color reproductions.
Mr. EISENBERG. Mr. Stombaugh, were the shades in--were the shades of
the dark blue cotton fibers uniform throughout the shirt which is
pictured in Commission Exhibit 673?
Mr. STOMBAUGH. No sir; the dark blue fibers had some lighter shades and
some slightly darker shades.
Mr. EISENBERG. About how many different shades?
Mr. STOMBAUGH. There were only about three in this.
Mr. EISENBERG. Do you recall how many dark blue fibers you got from the
butt plate?
Mr. STOMBAUGH. I believe a total of six or seven fibers from the butt
plate and three of them are blue fibers and all matched.
Mr. EISENBERG. Do you recall whether they were one or more shades?
Mr. STOMBAUGH. Two shades.
Mr. EISENBERG. So that two of the fibers were two different shades of
blue?
Mr. STOMBAUGH. Yes.
Mr. EISENBERG. And they matched two different shades of blue in the
shirt out of a total of three different shades of blue?
Mr. STOMBAUGH. That is correct.
Mr. EISENBERG. And you testified before there were about 50 to 100
ranges of shade of green cotton. What about the ranges in shades of
blue cotton?
Mr. STOMBAUGH. The same would apply to blue cotton.
Mr. EISENBERG. And the ranges in shades of orange yellow cotton?
