Mr. GRAEF. Yes. I would say he was very punctual in his arrival to work. He began working under me and I began the process of teaching him how to use our equipment. Mr. JENNER. All right. Now, he worked directly with you or under you or under your supervision and direction? Mr. GRAEF. That's correct--that's correct. He was with me a great part of the time. Of course, there are various times when I couldn't be with him, but for the better part of the first 3 or 4 months of his employment--he worked for us approximately 6 months. Mr. JENNER. Tell us what you taught him and how you attempted to train him and in what, and give me also, when you are doing that, his skills and aptitudes, as you recall them at the beginning? Mr. GRAEF. Well, as I have explained, the most we hope for in a person is that perhaps any past skills they have will help them in learning our work, but basically our work is so different that there is no experienced help, and everyone who comes into the department is automatically a trainee. Mr. JENNER. And he fell into that category? Mr. GRAEF. That's correct. All our cameras are different from the ordinary cameras you find in commercial printing shops or printing establishments. Mr. JENNER. Are these portable cameras or fixed cameras? Mr. GRAEF. No, fixed cameras--dark room cameras. Mr. JENNER. When I used the expression "fixed," I had in my own mind that they would be these large-size cameras, fixed in the sense that they would be adjacent to a wall or a bench or a table. Mr. GRAEF. Or the floor? Mr. JENNER. Or the floor. Mr. GRAEF. Yes. Mr. JENNER. And be so heavy as not to be portable or so firmly secured as not to be removable? Mr. GRAEF. Yes; that's right. Mr. JENNER. Would you indicate their size? Mr. GRAEF. I would say approximately 8 feet long total length, with 6 or 7 feet of the front of the camera projecting through a wall, which on the outside of that wall have the exposure lights to light whatever you are going to shoot. Then, the back of the camera sticks through the wall in the darkroom and on the back of the camera, of course, you place your light-sensitive film and make your exposure this way. Mr. JENNER. And do you use light-sensitive film plates? Mr. GRAEF. No; ordinary commercial Litho film or Ortho film that are generally available from large companies. Mr. JENNER. Indicate the size of the frames?
