In About Photography and the Law, entertainment and media expert witness Professor Jeff Sedlik writes:
A photography expert can analyze a photograph using forensic methods to determine the circumstances under which the photograph was made, and to reveal details of the photograph not visible to the naked eye. A photography expert may also use photographic equipment to conduct an analysis of a location, accident scene or crime scene, or to create simulations or reenactments. Photography experts can provide consultation and/or testimony or litigation support for attorneys, plaintiffs or defendants in photography litigation.
