Features
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.
