Tonal response and noise analyses for B&W patches La*b* color error and Color analysis News– Imatest 5.2: a Color Difference Visualizer (separate from Colorcheck) has been added so you can interactively examine the appearance of color differences. Color/Tone Auto can be used as a direct replacement for Colorcheck. Color/Tone Interactive, which has a highly interactive GUI, is useful for examining details of a camera’s color, tonal, and noise and SNR performance. We recommend these modules for new projects.

support for a great many color and grayscale charts (including the Colorchecker SG),.The newer Color/Tone Auto fixed, batch-capable) and Color/Tone Setup highly interactive) modules perform all Colorcheck calculations and have a number of additional features including It is useful for including in scenes for evaluating white balance. The smaller ColorChecker Passport is also available.

The quality of the chart is very high- each patch is printed separately using carefully controlled pigments. The X-Rite ColorChecker is an 8 x11″ inch chart consisting of 24 patches with 18 familiar colors and six grayscale levels with optical densities from 0.05 to 1.50 a range of 4.8 f-stops (EV). Algorithms and equations can be found in the Colorcheck Appendix. The ColorChecker can be photographed in isolation or as part of a scene. It is particularly useful for measuring the effectiveness of White Balance algorithms and settings under a variety of lighting conditions. Results for tonal response are similar to Stepchart.
