Forensic Investigation Photography (Basic to Advanced) Plus CSI Techniques (Doylestown, PA) May 8-12, 2023


This class will be held at the Bucks County Law Enforcement Training Center, 1760 South Easton Road, Doylestown, PA on May 8-12, 2023.

Crime scene photography remains one of the most important aspects of any criminal investigation. Whereas notes and sketches document items of interest that the investigator recognizes and records, a properly trained crime scene photographer will record everything of significance at a crime scene that is visualized in the viewfinder. A permanent recording can prove invaluable days, months, and even years after the crime scene has been released by law enforcement. Failure to obtain images while at the crime scene, or in a laboratory setting, that properly portray the item(s) of evidence in the lab, or piece of evidence at the scene, will likely result in the photograph not being accepted by the court, and thus being deemed unsuitable for presentation to the jury.

This 5-day course is designed for all personnel in the judicial process who are charged with taking crime scene photographs and/or presenting the images in judicial and administrative proceedings. The comprehensive course is also a designed for instructors charged with teaching proper photographic techniques to crime scene personnel, or students interested in entering this, or a related field. The course involves classroom lecture on photography theory and concepts followed by hands-on exercises. Nikon® equipment will be provided, so all students are operating identical equipment. Note: Students should bring a new, unused 8GB or larger high-speed USB storage device if they would like to keep the images they expose during training.

The student will leave the course with:

  • A high-level of understanding of digital cameras
  • Techniques for capturing quality images under various conditions
  • Acceptable standards for documenting crime scenes and physical evidence via photography
Each Student will receive a kit to use during hands-on exercises, and to keep.
