How it works

The Grey Balance card provides a consistent reference point for both exposure and colour calibration.

When used for exposure metering, the 18% grey surface reflects a standard level of light, helping your camera determine accurate exposure settings. This reduces guesswork, particularly in mixed or challenging lighting.

For white balance, the neutral grey allows you to set a custom balance in-camera or during post-production. Because it reflects red, green and blue evenly, it ensures your camera interprets colours correctly under the specific lighting conditions of your shoot.

Its larger size makes it easier to position within the frame, especially when working with multiple subjects, wider scenes or video setups.

Why choose this product

Lighting conditions can shift colour perception dramatically—cooler outdoors, warmer indoors, or tinted under artificial lighting. The ColorChecker Grey Balance gives you a consistent reference to correct for these variations, helping maintain colour accuracy across shoots.

Starting with correct exposure and white balance reduces time spent fixing issues in post, improving efficiency and consistency across projects.
