X-Rite Classic Grey Card

The ColorChecker Gray Balance from Calibrite is an 18% gray card scientifically engineered to provide a precise, uniform surface that is spectrally neutral. It works as a reference against changes in perceived white tones, giving you the power to adjust your camera's color sensitivity to exactly match the ambient lighting conditions.

Measuring just 8.5 by 11 inches, it's perfectly portable on location or in the studio and features millimeter markings along its edge to serve as a quick measuring tool or scale reference.
