For forty years, PAUL KAYFETZ, INC. through Mr. Kayfetz' expert testimony, has routinely admitted the following into evidence:

• Driverseye Visibility Studies
• Night-Time Photography
• Computer and Video Simulations
• Accident Reconstruction Photos
• Photogrammetry Photo Measuring 

Our computer engineers, video engineers and engineering photography experts:

• Apply Accepted Engineering Measurements Procedures
• Have Published Numerous Peer-Reviewed Engineering Papers
• Use HD Video Systems that Produce Movie Theater Quality
• Apply Cutting Edge Computer Techniques for Lifelike Photorealistic Images (not Computer Cartoons)
• Coordinate with the Best Accident Reconstruction and Human Factors Experts for Technical Accuracy

PAUL KAYFETZ, INC. frequently helps plan complete technical testing, visibility study, computer simulation and demonstrative evidence strategy - coordinating a group of technical witnesses who are independently retained by counsel. This is requested by many clients because of Mr. Kayfetz' track record, his previous career as an attorney, his extensive contact with top experts from his 40 years experience as an Engineering Photography consultant working with the best forensic witnesses on many of the major cases during those decades, and upon his membership and participation in major engineering societies.

Each year. Mr. Kayfetz helps attorneys win and save hundreds of millions of dollars in verdicts and settlements. This results primarily from his experience and expertise. It also stems from his ability to discover measurements from existing photos. PAUL KAYFETZ, INC are ahead of everyone in their field because they invest in HD cameras costing $250,000 each, six figure computer systems, custom engineering computer programs, and staff engineers - not artists.

A major part of their work is evaluating and keeping out of evidence opponents' forensic photography, computer simulations, or computer animations which do not comply with the rules of evidence. This has swung multi-million dollar results several times in recent years.
