The ColorChecker Gray Balance Mini is the smaller version of the standard-sized grey balance card, measuring only 63.5 x 109.0mm.
Using the ColorChecker Gray Balance Mini for reflective spot exposure metering will give you the confidence that your images will be exposed as accurately as possible. The ColorChecker Gray Balance Mini is a pocket-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 is produced through the configuration of cameras, lights and film.
It’s portable enough to take wherever you go!
