The ExpoDisc Portrait Filter effectively adds pleasing red tones to the entire image, producing an image with subtle red highlights in the hair and skin.

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.

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. ExpoDisc filters are available with quick pressure release mounts in six standard sizes from 58mm to 82 mm, and in flats for the 4x4 box systems from Lee.
