Features

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.

The portrait-based ExpoDisc was designed to effectively deliver a custom white balance reading with your flash system of choice: with the disc in place, simply base your white balance customization upon an exposure using your flash system.

The ExpoDisc can effectively be used with step-up rings, so if you use lenses with varying filter size specifications you can buy one ExpoDisc for your largest lens and appropriate step-up rings for your smaller-diameter lenses

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

: • 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 from 180 degrees and passively transmits 18% of it through to your camera's light meter; The resulting "gray frame" accurately represents the average colorcast of the light in which the photograph is taken.

: • From this gray frame, you then can set a custom white balance that results in accurate color in most lighting conditions; Your camera effectively compensates for and neutralizes the colorcast it sees through the ExpoDisc "gray frame"
