Calibrite ColorChecker Gray Balance
Exposure 18% Gray Balance for Photo and Video from Capture to Edit
The ColorChecker Gray Balance is the largest size available Gray 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 configuration of cameras, lights and film.
The perceived colour of white changes based on ambient conditions—outdoor it is perceived to be cooler, indoor, warmer, and under fluorescent light, greener. ColorChecker Gray Balance gives you the power to adjust your digital camera's colour sensitivity to exactly match the ambient lighting conditions; in effect, changing what that the camera “sees.” Even in a controlled studio environment, establishing an accurate custom grey balance ensures an accurate image from the start of each new photo session.
