Lightning Powder Photo ID Cards

Each time a new roll of film is started at a crime scene, the first exposure should be of a card listing the case number, date and photographer. Each of these Photo Identifier Cards has a gray scale, a color scale and spaces for writing necessary case information. Submit the cards with the roll of film so the darkroom technician can match the gray scale and colors to produce a color-accurate photograph. The small Photo ID Card measures 4x6 inches.
