A photo log is an ordered collection of photographs that can be easily referenced for future use. When a crime scene is documented, numerous photographs are taken at the scene. The scene is photographed in wide shots, medium shots, and close-ups of every relevant object in the scene. There can literally be hundreds of photos. It is important to document every detail because you never know if something that seems irrelevant at the time is later going to turn out to be extremely important. At the end of processing and printing all of the photos, a detailed and orderly log must be kept so the pictures can be referenced again in the future. Also, an orderly photo log can also help keep pictures from getting lost.
