Mr. Shaneyfelt. It is true. That is the negative from which that exhibit was made. The negative was exposed in the camera which is marked Commission Exhibit No. 750. I exposed it myself.
Mr. Eisenberg. Mr. Chairman, may I have this negative admitted as 752?
Mr. McCloy. It may be admitted. That is the negative from which that exhibit was made?
Mr. Shaneyfelt. Yes.
(Commission Exhibit No. 752 was marked and received in evidence.)
Mr. McCloy. And you took that picture?
Mr. Shaneyfelt. I took that picture myself.
Representative Ford. Is this a recognized technique or procedure used in or among experts such as yourself?
Mr. Shaneyfelt. Yes. We have used this technique of camera identification with film on several occasions. It doesn't arise too often. As it normally arises, the majority of examinations that I have made in this connection are the identification of a camera that has been stolen and the serial number removed so that it can't be identified, the owner cannot identify it. We then take the owner's film and the camera that has been recovered and make this examination and determine that this is in fact the camera that the owner's film was exposed in, thereby showing ownership.
So, it is a recognized technique, we do it regularly.
