ExpoDisc Digital White Balance Filter
The White Balance Solution for Digital Cameras and Digital Video

The patent pending ExpoDisc Digital White Balance Filter provides a fast and easy custom white balance solution for professional photographers and videographers.

The ExpoDisc is a custom white balance filter that allows photographers to accurately color balance their digital cameras at capture without having to worry about the accuracy of the camera's own auto white balance (AWB), or fumble with cumbersome targets.

For JPEG files, simply read and set white balance with the disc in place before shooting to eliminate the need for post-capture color adjustments. Or, if shooting RAW files, simply shoot a gray frame for your post capture white balance reference.

Each ExpoDisc is manufactured and individually hand calibrated to fall within strict tolerances of light transmission and color neutrality. Consisting of multiple layers of carefully selected materials, the ExpoDisc is guaranteed to be within +/- 2% of neutral for demanding photographic professionals.

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.
Blue, green, red and yellow colorcasts are not uncommon. Until now, photographers have had to rely on grey / white cards and targets to solve this problem.

But the ExpoDisc acts just like an 18% grey card when used to measure the incident light, and as such can be used instead. The sophisticated design enables the ExpoDisc to receive, scramble and passively transmit mixed light from a wide angle in front of the disc through to the cameras sensor for a more accurate and efficient white balance correction.

Simply take a picture with the ExpoDisc installed and save the resulting image for your custom white balance setting. Your camera will then compensate for and neutralize the colorcast it sees through the ExpoDisc.

Get the white balance solution that is quickly becoming the preferred method of achieving accurate color balance for professional photographers today. ExpoDiscs are suitable for use with 35mm film and digital SLR cameras, and digital video.
 

They are available for professional lenses in six standard sizes from 58mm to 82mm. Additional sizes are available in 4x4 and 4x5.65 configurations for professional photographic and video filter box systems from Lee, Schneider, Chrosziel and Arri.
