These Lab renditions of Macbeth ColorChecker, ColorChecker DC, and ColorChecker SG (attached archive contains three 16-bit Lab TIFF files of the targets; if you need them larger please upsize in Photoshop using "Nearest Neighbor" method in Image -> Image Size) can serve as a visual reference as well as for adjustments "by numbers" during raw conversion and post-processing.

Please note that ColorChecker SG contains a structure very similar in appearance to 24-patch regular ColorChecker; but the values of patches are in fact different.
