Optical dynamic range
WebMar 10, 2024 · An imaging system’s dynamic range determines the darkest and brightest signals that it can detect [ 7 ]. When the dynamic range of an imaging system cannot cover the intra-scene dynamic range (IDR) of samples, a trade-off must be made between the loss of weak signal and intense signal saturation. It becomes even more challenging for SIM … WebIn short, dynamic range describes the measurement between maximum and minimum values. While not specific to photography, in this article on dynamic range in photography …
