ExpoDisc 2.0 82mm Professional White Balance Filter

The ExpoDisc 2.0 is a professional white balance filter in 82mm size designed to achieve accurate custom white balance settings in camera by measuring the color temperature of the ambient light in a scene rather than reflecting it. It fits over the lens filter thread and is used by pointing the camera toward the primary light source and taking a custom white balance reading, allowing the camera to calibrate its white balance to the exact color temperature of the shooting environment. This incident light measurement approach produces more accurate and consistent white balance results compared to conventional grey card or automatic white balance methods, particularly in mixed lighting conditions or under artificial light sources with complex spectral characteristics. The ExpoDisc 2.0 update incorporates a warm tone filter variant alongside the neutral version to provide a slight warming effect to the custom white balance reading when desired.
