Jeff Suway: quantifying luminance with a camera, video analysis, & his love of retroreflective tape

On this episode, I interviewed Jeff Suway, proprietor of JS Forensics and collision reconstruction/human factors polymath. Jeff is on my short list of people to call if I need help deep diving some topic, whether it's EDR, video analysis, or conspicuity. In this episode we'll discuss how Jeff got into recon, the current state of his firm, Jeff's real love, retro reflective tape, quantifying luminance with a camera, video analysis, and much more.
