This military-developed text consists of nine lessons dealing with investigative photography. Covered in the individual lessons are the following topics: light (light as the basis of photography, the behavior of light, the composition of white light, light transmission, reflection and absorption, illumination, and pinholes and light); camera lenses and optics (types of lenses, lens defects, lens focal length, aperture setting and light control, lens angles, image size, the circle of confusion, and lens focusing characteristics); cameras; films (black and white films, color film, diffusion transfer reversal system materials, and film selection); principles of exposure (basic outdoor exposure, interchanging the stop and shutter speed, light meters, exposure with artificial light, filter effects, filter types, and film factors); photographic chemistry and processing (film development, negative developing solutions, the effects of developer and negative density, developer life, processing the negative, negative processing problems, printing paper and printing, and processing the print); copy and small object photography (photographing small objects and fingerprints); and crime scene photography (photographing crime scenes and articles of evidence). Each lesson has an objective, suggestions for study, a reading assignment, review exercises, and answers to the exercises. A course exam is also included, but no answers are available. (MN)
