Get the white balance solution that is quickly becoming the preferred method of achieving accurate color 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 color fidelity.

Until now, photographers have had to rely on gray/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 "gray frame".

You then set a custom white balance using the "gray frame" that results in accurate color in most lighting conditions. Your camera essentially compensates for and neutralizes the colorcast it sees through the ExpoDisc.
