Introducing the carefully selected test chart from ImageEngineering!
The color reproduction test chart (color chart) is used to check the quality of a camera's color correction (reproducibility). On the other hand, this can also be seen as a subjective analysis of preferred colors and a measurement of color reproduction. In the latter case, the image is converted to the CIELAB space, and the color values are compared with the measured colors of the original target. A good method is to use the camSPECS device to measure spectral sensitivity. A commonly used chart for cameras in this field is the X-Rite ColorChecker, but ImageEngineering sells it as "TE188," while the IT8 for scanners is sold as "TE258." "TE226" is a transparent extended version of the ColorChecker. For cameras, the extended version becomes the X-Rite ColorChecker SG, which is sold as "TE230" and has become the standard test chart.
