Get accurate colour in difficult lighting with the patented ExpoDisc, the fast and easy digital white balance filter. Simply read and set white balance with the ExpoDisc in place before shooting and you’ll reduce or eliminate the need for post-capture colour adjustments. Get the white balance solution that is quickly becoming the preferred method of achieving accurate colour balance for professional
photographers today.
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 colour fidelity.
Until now, photographers have had to rely on grey/white cards to solve this problem.The 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 and passively transmits 18% of it through to your camera’s light meter, effectively producing a ‘grey frame’. You then set a custom white balance using the ‘grey frame’ that results in accurate colour in most lighting conditions. Your camera essentially compensates for and neutralizes the colourcast it sees through the ExpoDisc

An Introduction for Film Use
The reflected-light-metering systems provided on most SLR cameras are very fast, convenient, and are good enough for general use in capturing images on negative films. However they are not good enough for satisfactory use with color slide films, nor for controlling image tones, rather than simply recording them. The ExpoDisc is the key to direct incident-light-metering methods that are a little slower than reflected-light-metering methods, but they do provide for consistently better exposures on any film in any lighting. The ExpoDisc offers the photographer accurate control of image tones whenever he wishes.
