The YE0197 is designed for evaluating the opto-electronic-conversion-function of a camera. The chart consists of a circular ordered 12-step-gray scale on a gray background.
This chart has 36 low-noise density patches with density steps of approximately 0.1, for a density range of at least 3.2 (density from base to base + 3.1 minimum). A nearly circular patch arrangement ensures that vignetting has minimal effec
