Even the best digital cameras are incapable of consistently delivering accurate color without the user performing a custom white balance. Auto (AWB) and preset white balance functions often produce maddeningly inconsistent results. Images shot without a correct white balance may have unnatural looking red, yellow or blue tints that are time consuming and difficult, if not impossible to correct.

Recognizing the importance of custom white balance to good color, digital camera manufacturers have designed their cameras to take advantage of a custom white balance. A custom white balance calibrates the camera to the exact color temperature of light illuminating the subject.

The ExpoDisc is a custom white balance filter that allows digital photographers to quickly and easily set an accurate custom white balance. Consistently producing excellent results in natural, artificial, and studio lighting, the versatile ExpoDisc even excels in difficult mixed lighting environments.

The ExpoDisc is far easier to use than any gray card, white card or calibration target. Simply place the ExpoDisc in front of your lens and capture the incident light while setting your camera's custom white balance. Using an ExpoDisc custom white balance will virtually eliminate the need for RAW or JPEG post-capture color adjustments.

ExpoDisc technology takes a unique approach to setting a custom white balance and producing accurate color. The ExpoDisc essentially uses your camera's built-in custom white balance capability to turn the camera into an incident color-metering tool. This approach avoids the common problems and inconveniences associated with using gray cards, white cards and calibration targets: unwieldy size, unwanted reflectivity, improper angling and difficulty of filling the frame.

Each ExpoDisc is constructed of carefully selected and matched optical grade materials, then hand-calibrated to strict tolerances of color neutrality and light transmission.

The ExpoDisc is suitable for use with any digital SLR and digital video camera with a white balance function.

Comments about Expoimaging Expoimaging ExpoDisc Digital White Balance Filter, 67mm:

I am a colorblind photographer. I can see detail that no one else sees. With that being said I can't set white balance and tell if it's off. My photo lab costs a ton to do the corrections needed to make my photos ok for sale. My lab tech called me after the first order to ask who was doing my corrections before I sent them for print. It took alot of pictures to prove to him that they were not corrected just correct. Best one bill I have ever spent. Works like a dream with my d200.
