Des Plaines, IL (June 11, 2007) — The American Society of Safety Engineers’ new book by John Wenzel, Jr., CFI, CGSO, titled “Investigative Photography” provides needed information for occupational safety and health professionals on how to improve their investigative photo skills and the role these photos play in investigations and in legal proceedings.

This new book contains strategies that safety, health and environmental (SH&E) professionals can use to develop and exercise the skills necessary to increase their investigative photography skills under a variety of conditions, and provides guidance on many aspects of the legal use of photographs from ownership and control issues to protecting trade secrets.

Written by an occupational safety and health professional and alumnus of the U.S. Department of Defense, the University of Maryland Fire and Rescue Institute and more, Wenzel shares his experience and tips such as the methods of documenting and collecting evidence involving motor vehicle accidents, pesticide releases, and fatalities. Some of the evidentiary topics discussed include: standard photographic sets; presenting photos in court; presentation techniques; and making the case for taking a photograph.

Safety concerns for the investigative photographer are also covered from personal protective equipment (PPE) to protection from falls and around machinery and moving vehicles, as well as safety while using flash equipment. The book also has a section of practical exercises including PPE, safety briefings, existing light photography, flash bouncing and photographing reflective surfaces and motor vehicles. Basics such as how to hold a camera and different lighting techniques along with how to hire and work with contract photographers are also included.

Wenzel is a recognized expert in the field of investigative photography. He is the founder of Precision Image Photography Company and has testified to investigative photographs in hundreds of legal cases. Wenzel has served as an occupational safety and health compliance officer and regional supervisor for the State of Maryland.
