Visual Evidence Analysis and Testimony · Justin Weber

A camera records what its settings allow. A person at the scene sees something else.

I evaluate the gap between what a photograph or video recorded and what a person present would have perceived, and I explain it in a written report, at deposition and at trial.

Typical questions

• Does this video show the lighting a person would have perceived at the time?

• How did auto-exposure, compression or shutter speed shape what the footage shows?

• Was the recording made under conditions comparable to the incident?

• What did the scene look like across a human field of view?

Scope

• Within scope

  Representation versus perception · Camera behavior: exposure, dynamic range, shutter, codec · File and metadata review with standard tools, limits stated · Scene documentation and demonstratives, such as field-of-view panoramics

• Referred to other experts

  Illumination measurement and lighting engineering · Accident reconstruction · Forensic image authentication · Medical causation

Engagement

Experience

Retained as an expert in civil matters involving a railroad crossing and hotel premises liability, including deposition testimony. 20 years of professional cinematography and post-production.
