The ExpoDisc Digital Warm Balance Filter is designed for professional photographers, videographers, and serious amateurs. The 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 abias 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 many sizes.
