Curriculum Vitae

ENGINEERING PHOTOGRAPHY is the combining of photographic and optical techniques with engineering measurement procedures.
Areas of specialization are:

Visibility Studies -- HD-video and/or still photography, with related analysis, accurately depicting visibility under conditions relevant to the subject incident. Visibility studies can be performed, and proper foundation established, day or night. Vehicles, pedestrians, buildings, trees added or removed accurately with photorealistic appearance using engineering computer methods.
Comparison Photogrammetry -- Analog techniques of determining measurements of skidmarks and other objects from accident scene photographs. Analog techniques involve overlapping measurement grids included in a comparison photograph taken from the same viewpoint as the accident photo. The result is usually more accurate than purely mathematical approaches, and is easily understood by any viewer. Computer applications supplement this approach.
Computer Virtual Reality Simulations -- Video, film, still photos, and/or artwork computer-combined in film or 3-dimensional video presentations based on engineering reconstruction input.
Video -- High speed (slow motion) or broadcast quality video recordation of vehicle testing, machine operations.
Expert Witness -- Qualified as Expert Witness more than 400 times since 1963 (never denied qualification) In the Following Jurisdictions: Federal and State Courts in Hawaii, Alaska, Washington, Oregon, California, Nevada, Arizona, Colorado, Oklahoma, Texas, Missouri, Florida, Alabama and Washington, D.C.

BACKGROUND:

Engineering Photography: -- Primarily based on the experience obtained during more than forty years of consulting work. Related employment experience involved designing and operating measuring devices using optical and photographic principles. Related foundational academic work includes courses in basic engineering measurements, analytic geometry, calculus, physics, and chemistry at UC Berkeley School of Engineering.
Visibility Studies: -- More than 4000 visibility studies performed during the past forty-four years, of which some 1800 were at night. The techniques of defining testing parameters, making related measurements, and analyzing the results have been derived in collaboration with many engineers, physicists, and human factors psychologists who have participated in producing these studies.
Comparison Photogrammetry: -- A methodology involving parallax location of camera positions at the scene, the establishment of a grid system of coordinates, and the use of overlay prints has been developed through application in more than 2000 cases. Computers are now extensively used.

RELATED EMPLOYMENT:

Research Technician, Institute of Engineering Research, UC Berkeley, 1960-61, designing and using optical testing apparatus for measurements on Air Force research projects (rocket nosecone materials).
