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 a pocket size version of the 18% gray reference square in the standard 24-patch ColorChecker. The gray 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 perceived color 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 color 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 gray balance ensures an accurate image from the start of each new photo session.
The ColorChecker Gray Balance target can be used for a variety of applications:
- Digital Photography: Exposure metering and gray balance. Adjusts your digital camera's color sensitivity to exactly match the ambient lighting conditions
- Traditional Photography: Check films, lights, filters and paper.
- Cinematography (Television and Video): Verify gray balance is produced through configuration of cameras, lights and film.
And at only 4 x 7 inches, it’s portable enough to take wherever you go!
