The ColorChecker Turns 50: Calibrite Marks the Anniversary

The ColorChecker chart hits 50 years old, and Calibrite has put up an anniversary site with a timeline tracing the product from its 1976 debut through its Gretag, GretagMacbeth, X-Rite, and Calibrite ownership changes. The site breaks down the purpose of all 24 patches and covers the Digital SG version's 140-square layout, including a 17-step grayscale ramp and 14 skin-tone targets.
