Mr. Shaneyfelt. Yes.
Mr. Eisenberg. Could you give that opinion?
Mr. Shaneyfelt. I believe that the sight does not appear in the reproduction of the photograph on Shaneyfelt Exhibit No. 4, because it was not retouched to intensify the detail of the sight, and, therefore was lost in the engraving process. I do not believe that there was any retouching over the sight in order to purposely obliterate it from the reproduction in Exhibit No. 4.
Mr. Eisenberg. Now, is there generally a loss of detail in reproduction of illustrations appearing in newspapers, Mr. Shaneyfelt?
Mr. Shaneyfelt. Yes; there is. This is apparent in other areas of this photograph when compared with Shaneyfelt Exhibit No. 1, in areas of Oswald's shirt, where wrinkling appears in Exhibit No. 1, and is lost in the reproduction. Also, the wrinkles in the dark areas of the trousers are not reproduced in the halftone process, but this detail is lost by the process.
Mr. Eisenberg. What is this halftone process which you mention?
Mr. Shaneyfelt. This is the halftone process by which a continuous tone photograph, such as Exhibit No. 1, is photographed through a screen so that it can be broken up into a dot pattern of black dots on a white background and white dots on a black background to give the appearance of a continuous tone in the printed newspaper reproduction. And this is the only means by which a continuous-tone photograph can be reproduced.
Mr. Eisenberg. Why is it called a halftone process?
Mr. Shaneyfelt. I don't really know the answer but I would assume that it is because it gives you the tones in between black and white, or the halftones.
Mr. Eisenberg. Now, a loss of detail is inherent in this process, is it?
