218 MOTION PICTURE HANDBOOK case ports A and B should be located 6 inches higher, or where there is an extraordinary steep pitch in the projection, in which case ports C and D must be located lower, as possibly must also ports A and B. Q, y X.-Jf *--i Figure 84. In cases of very steep projection the height of the ports may be located as per Fig. 84. First locate the height of the operator's eyes when seated in operating position. I have assumed this to be 4 feet from the floor and 3 feet away from the wall, at A, Fig. 84. Now measure the exact distance from Point A to the bottom of the screen, using the elevation plan of the theatre, if there is one, also the exact vertical height from the bottom of the screen to point A, Fig. 84. Draw a rough plan, to scale, by laying off the height of the operator's eye above the bottom of the screen, and the horizontal distance to the screen. Then draw line S, Fig. 84, extending from point A to bottom of the screen.
