ABSTRACT
When a camera converts a three dimensional scene into a TV picture, it leaves an imprint of lens height, camera tilt, distance from subject and lens angle. We can detect these decisions in any image by examining the position of the horizon line and where it cuts similar sized figures. This will reveal camera height and tilt. Lens height and tilt will be revealed by any parallel converging lines in the image such as the edges of buildings or roads. The size relationship between foreground and background objects, particularly the human figure, will give clues to camera distance from objects and lens angle. Camera distance from subject will be revealed by the change in object size when moving towards or away from the lens (see Composition and the lens, page 124).
