Get accurate color 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 color adjustments. 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.

ExpoDisc Digital Warm Balance Filter
Warming Solution for Digital Cameras and Digital Video


The new filter is designed for professional photographers, videographers, and serious amateurs.

The new filter produces custom color at the point of capture. Photographers no longer have to shoot through extra glass, carry inconsistent and cumbersome cards, or spend hours on the computer in post-production color correction. Users just need to read and set white balance with the ExpoDisc Digital Warm Balance filter in place before shooting to produce portraits and landscapes with warmer, more pleasing colors.

The Digital Warm Balance Filter is a calibrated, colored diffusion filter with a bias that forces the digital camera to add precise quantities of red and green color to a neutral balance. The filter is excellent for warming (or balancing) skin tones in indoor or outdoor portraits and scenery. It decreases color temperature; adds healthy skin tone to images shot in open shade or overcast conditions; slightly reduces the bluish cast on overcast days or at high noon; reduces excess blue from flash indoors or in daylight flash-fill; as well as warms sea, sky and high altitude shots.

Each ExpoDisc comes with a card recording its exact density and primary color characteristics. The ExpoDisc filter works with digital cameras and digital video, and is available in six standard sizes from 58mm to 82mm.
