ColorChecker White Balance target is a spectrally neutral to deliver accurate white reproduction. Use it to perform custom in-camera white balance to guarantee precise, uniform, neutral white - under any lighting condition. The ColorChecker Custom White Balance target delivers accurate white reproduction. As lighting conditions change, your camera shifts the way it reproduces white; resulting in color shifts in your photos. Most white balance targets arent neutral and could cause colors to shift under different lighting conditions. But the ColorChecker Custom White Balance target is a scientifically engineered, absolute neutral white reference that prevents color shifts and provides precise, uniform surface that is spectrally neutral - in any lighting condition. That means you can be confident your cameras image is as close to real life as possible. ColorChecker White Balance also gives you a way to adjust your digital cameras color sensitivity to exactly match the ambient lighting conditions; in effect, change what that the camera "sees." The perceived color of white changes based on ambient conditions-outdoor it is perceived to be cooler, indoor it is perceived to be warmer, and under fluorescent light, greener. Even in a controlled studio environment, this can be a problem. Whether on location or in your studio, establishing an accurate custom white balance before each photo session ensures accurate colors from the start.
