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. Cards are sold in pads of 25.
Choose from Large 8.5" x 11" or Small 4" x 5.4" using the pull-down menu.
