Imaging Evidence in the Electromagnetic Spectrum

WHITESBORO, TEX. - Aug. 20, 2019
Seeing can be deceiving with preliminary bruising, tattoo, and video studies. “Imaging the Unseen,” a four-hour seminar at the 2019 LEVA Digital Multimedia Evidence Training Symposium, will explore the electromagnetic spectrum and its relevance to visible, infrared, and ultraviolet digital photography, videography, and analysis. With coursework for government and private security video professionals, the 30th annual symposium of the Law Enforcement and Emergency Services Video Association International runs Oct. 7-11 in Denver.

While the investigative potential has been made clear for a wide variety of evidence, the full extent of such similar effects on persons of interest, as well as their clothing and vehicles, captured on surveillance video has yet to be fully realized. As a result, law enforcement professionals frequently release inaccurate BOLOs.

“Forensic video analysis is a proven, powerful tool in the arsenal of law enforcement for our judicial process, but training is paramount to help ensure credibility and confidence,” explained Jan Garvin, LEVA Executive Director. “Showcasing emerging technology is always exciting. Demonstrating how one can be trained to use infrared and ultraviolet light to improve identification of suspects, cars, and other evidence of interest to investigators is a game-changing objective.”

“Imaging the Unseen” will be led by Stephanie L. Hoffman, a crime scene investigator certified by the International Association for Identification, who has taught and/or developed multiple sections of almost two dozen college-level forensic science courses. She will highlight how various bruising, clothing, hair and skin tones, vehicles, and tattoos are different when seen through VIS, IR, and UV filters on DSLR and IP security cameras. Attendees will also have the opportunity to visualize various items with select camera, filter, and light source combinations in order to observe the effects in real time.

LEVA’s schedule of training sessions focuses on a variety of topics, including forensic audio analysis, image authentication, investigative animations, and courtroom testimony for forensic video experts. LEVA membership is not required to attend LEVA 2019, but classes can earn hours toward LEVA certification. Several classes have limited availability and require pre-registration.

ONE OF THE CHALLENGES of writing and editing a magazine is telling a story in a relatively small amount of space. Sometimes it seems like there is never enough room to say everything that needs to be said. I find myself making tough decisions about what parts stay and what parts go.
