A police photographer takes pictures during crime investigations. In this role, you capture images throughout a crime scene to record evidence or other visual information that detectives can use during their investigation. Your responsibilities can vary, depending on the procedures of the department in which you work. Crime scene investigators may collect or locate evidence and then direct a photographer to take pictures of specific items or areas within the crime scene. Some photographers also collect measurement, location, and description data while they take photos. In some instances, a photographer may not take directions from other personnel, but conduct their duties according to their department's crime scene processing procedures. Your photos must provide context for the evidence, close up images, and overall crime scene images. Many police photographers also process their own film to avoid potential contamination.
