Technically, this is juvenilia (the author was 14 when he wrote it) but it reads with the ease and simplicity of any good instructional pamphlet. Himself an early dedicated shutterbug, young Mr. Kohn shows a nice appreciation of the twin devils of juvenile hobbyists-- lack of equipment and lack of cash. He keeps to the simple cameras and suggests the inexpensive techniques throughout. A short history of the camera and the principles on which it is based is followed by a series of chapters on lighting, focus, film, the most often encountered mistakes and developing. The last chapter has particular juvenile appeal--careful instructions on how to achieve startling effects through double exposure, time exposures, etc.
