Representative Ford. This would be true in every picture taken?

Mr. Shaneyfelt. That would be true of every picture taken and is true of virtually every camera—every roll-film type camera. It would not be true of a press-type camera where the film is loaded into separate holders; then the holder becomes the thing that will leave identifying characteristics.

On any 35 mm. or Leica camera, roll-film camera, box cameras of all types, having an arrangement, where the film goes across an opening leaving an exposed area at the aperture and unexposed area around the aperture, this would be true.

Mr. Eisenberg. When you say "virtually every camera" you are including every type of camera with this type of aperture?

Mr. Shaneyfelt. Yes; I would include every camera with this type of film arrangement and aperture.

Mr. Eisenberg. You held up a negative before——

The Chairman. Just a moment, gentlemen, you will excuse me, I must go over to the Court now. You will be able to proceed the rest of the day, will you?

Fine. I will be back as soon as I finish.

(At this point the Chief Justice left the hearing room.)

Mr. Eisenberg. Mr. Shaneyfelt, you were holding up a negative which appears to be a negative of a simulated photograph you showed us before, Exhibit 748. Is it such a negative?
