History of the ExpoDisc
The inventor of the ExpoDisc was George Wallace who originally designed the filter for slide film. The idea was to turn the meter inside a 35mm camera into an incident meter by putting a prismatic diffusion filter in front of the lens and engineering it to pass exactly 18% of available light to arrive at the film plane, thus admitting the same amount of light which the average subject is assumed to reflect). Besides metering perfect TTL exposures for film cameras, the ExpoDisc also generates a superb neutral reference for colour capture. Thats because it passes the light it receives without adding any significant colour cast of its own and thereby identifying the unique colour cast that exists in every light condition!
Each unit is individually calibrated and colour corrected for neutrality, making digital white balance fast and easy. This easy to use tool allows every digital SLR camera to generate an impressive white balance, at capture, in almost all lighting conditions.

The ExpoDisc can turn a camera into an incident light-meter and even a densitometer! For details:
