DR 36 Color with a new patch order to reduce the impact of stray light ghost images on dynamic range measurements and additional color patches.
Purchase Chart
The ColorGray-44 chart is designed for image quality testing, featuring 6 saturated RGBCMY colors, 18 ColorChecker-like patches, 20 grayscale steps with precise density increments. It includes logarithmic wedges and slanted edges for resolution analysis. A reference file for accurate evaluation accompanies the chart. Optimized for self-illuminated endoscopes, the chart avoids placing critical features at the center to minimize the impact of specular “hot spots.” It can also be pre-distorted for cameras with strong barrel distortion and cropped as long as registration marks remain visible.
