The Calibrite ColorChecker Gray Balance Mini is a scientifically engineered 18% gray card to provide an accurate and homogenous surface that is spectrally neutral, thus rendering it suitable as a reference against changes in perceived white tones. This will allow you to adjust your cameras colour sensitivity to match precisely the ambient lighting conditions. This smaller, conveniently-sized grey card measures 108mm by 63.5mm and features markings along its edge that serves as a reference for the scale of the subject it is placed against and as a quick measuring tool.
