Mr. Eisenberg. That is the other half of the cartridge case?
Mr. Cunningham. Yes, sir. In other words, you are seeing the primer, the space between the primer and the brass on the cartridge case itself—on the questioned cartridge case this time—and the base of the cartridge case of the test is on the right. It looks like it is one. It is just the opposite side of the cartridge case from the other photographs.
In other words, you take the photograph of the most demonstrative marks—which look real good, naturally. The examination is of all the marks. That is the big difference. And this time you will see—it is very demonstrative—on each side of the hairline, a great deal of similarity between these marks.
Mr. Eisenberg. And the magnification here?
Mr. Cunningham. It is approximately 96 times.
Mr. Rhyne. Why do you vary the magnification?
Mr. Cunningham. The magnification of every photograph you take, sir, depends on the length of the bellows of the camera. The microscope will have a set magnification. But each time that you focus the length of the bellows can change, which will increase or decrease the magnification. Also with some photographs you mask off areas which are out of focus. You certainly would not want to print a whole negative where you have distortion. You bring into focus one small portion of the surface of that bullet.
If, say, one surface of the bullet is slightly flattened and the other surface is rounded—the rounded surface will be going out of focus much faster than the flattened side, and it would be very confusing. That is the type of thing. You mask differently.
Then when you have the negatives enlarged, you can enlarge one negative more than you do the other. So it can be based either on the length of the bellows, or on the amount you have enlarged it.
Mr. Eisenberg. Is that all the photographs?
