Here is how it works:Varying levels of colorcast typically occur in digital photography and require compensation as part of the process to create a photograph with good color fidelity. Until now, photographers have had to rely on gray/white cards to solve this problem. ExpoDisc is an easy to use custom white balance solution that eliminates the inconvenience and inconsistencies of other methods. It is a neutral diffusion filter that gathers ambient light from 180° and passively transmits 18% of it through to your camera's light meter. The resulting "gray frame" accurately represents the average colorcast of the light in which the photograph is taken. From this gray frame, you then can set a custom white balance that results in accurate color in most lighting conditions. Your camera effectively compensates for and neutralizes the colorcast it sees through the ExpoDisc "gray frame."
