In digital photography, getting an accurate white reading is a challenge for many cameras. However, doing so will save a lot of time in postprocessing and get you much sharper, more color-accurate pictures. The ExpoDisk is a simple tool to use to get better pictures.
Instructions
1. Select the proper disk size. Choose an ExpoDisk large enough to cover the lens and one appropriate for your type of photography. ExpoDisks are available in neutral and portrait versions. Neutral is designed for most standard photography, while portrait offers a softer edge for better portrait shots.
2. Turn on the custom white balance setting on your camera. How you do this will vary according to your type of camera; ExpoDisk provides detailed instructions for each major camera manufacturer.
3. Hold the ExpoDisk up against the lens. ExpoDisk is available in different sizes, including 58 mm, 62 mm, 67 mm, 72 mm, 77 mm, and 82 mm. You can screw the ExpoDisk into the filter threads if you buy the right size ExpoDisk for the lens threads; however, if you buy a lens with bigger threads than the ExpoDisk, you will have to get another ExpoDisk. Many photographers buy a 77 mm ExpoDisk and simply hold it against the lens.
4. Let the camera select an exposure if it is in Program mode, or choose the exposure if you are in Manual mode. With a Nikon D90, D300, D700 or D3, select the "White Balance" button and rotate the command until "Pre" is displayed. Release the "White Balance" button, and then press it until "Pre" starts flashing. Point the camera at the light source of the picture and then push the shutter button.
5. Store the white balance as "d-0" when "Good" is shown instead of "Pre." Select "d-0" in the white balance modes and take your picture.
