Mr. Ofstein. I'm not sure of the brand names we have.

Mr. Jenner. I'm thinking more of the size, weight, whether they are portable or aren't portable, or whether they are fixed or aren't fixed.

Mr. Ofstein. They are fixed, they move on a track to determine the size of the copy that is photographed, and they have fixed mounted lenses in the walls.

Mr. Jenner. And you move from one lens to another, is that the way?

Mr. Ofstein. No, sir; you mount the copy to be photographed on the board and you move that board, and the board that you put your film on—to get it different sizes.

Mr. Jenner. What is the character of the training?

Mr. Ofstein. Mainly they start you out with doing small jobs—just normal—what we call straight shots. It amounts to getting a size and photographing it and developing it, opaquing the negatives, and making nice clean prints, and then as you progress you do more difficult type work.

Mr. Jenner. Do you know what lithography is, lithographing?

Mr. Ofstein. No, sir; I have heard the term—that's all.

Mr. Jenner. Making metal plates?
