The ColorChecker Gray Balance is the largest size available grey balance card in the range, it’s the same size as the ColorChecker Classic Target at 215.9 x 279.4mm.
Using the ColorChecker Gray Balance card for reflective spot exposure metering will give you the confidence that your images will be exposed as accurately as possible. The ColorChecker Gray Balance card is the larger size version of the 18% grey reference square in the standard 24-patch ColorChecker. The grey is scientifically engineered to provide a precise uniform surface that is spectrally neutral, meaning it reflects equal amounts of red, blue and green in all types of light conditions.
The ColorChecker Gray Balance target can be used for a variety of applications:
Digital Photography: Exposure metering and grey balance. Adjusts your digital camera’s colour sensitivity to exactly match the ambient lighting conditions
Traditional Photography: Check films, lights, filters and paper.
Cinematography (Television and Video): Verify grey balance through the configuration of cameras, lights and film.
