Imatest CTO & Founder Norman Koren discusses rarely mentioned issue of lens flare that often limits a system DR of the imaging system in his presentation at SPIE EI 2018 on January 29:
"The dynamic range of recent HDR image sensors, defined as the range of exposure between saturation and 0 dB SNR, can be extremely high: 120 dB or more. But the dynamic range of real imaging systems is limited by veiling glare (flare light), arising from reflections inside the lens, and hence rarely approaches this level."
