The GretagMacbeth ColorChecker White Balance card is a full size version of the white reference square used in the standard 24-patch ColorChecker. This white is scientifically engineered to provide a precise uniform surface that is spectrally neutral (reflects equal amounts of red, blue and green) in all types of light conditions. The photographer can now have confidence that the cameraâ€™s raw image is as close to real life as possible.
ColorChecker White Balance gives photographers a way to adjust the digital camera's color sensitivity to exactly match the ambient lighting conditions, in effect, change what that the camera â€œsees.â€ The perceived color of white often changes based on ambient conditions - outdoor it is perceived to be cooler, indoor it is perceived to be warmer and under fluorescent light it is perceived to be greener. Even in a controlled studio environment, establishing an accurate custom white balance ensures an accurate image from the start of each photo session.
