The Original, Award Winning Professional White Balance Filter

Why You Should Set a Custom White Balance

Even the best digital cameras struggle with consistently reproducing accurate color. Images shot with inconsistent or incorrect white balance settings may appear unnaturally warm with too much yellow, or too cool with a cyan tint. Anyone who has wasted time color correcting images knows that fixing the color temperature and tint of photos or video can be a frustratingly difficult and time consuming process.

To help photographers cope with this problem, digital camera manufacturers designed their cameras with multiple white balance functions, including Custom White Balance, Automatic White Balance (AWB), and a variety of factory Preset color temperature settings for Sun, Shade, Tungsten, Fluorescent, Flash, and Cloudy. 

Unfortunately, unwanted color casts are far too common as Auto White Balance (AWB) often produces maddeningly inconsistent color results, and the fixed color temperatures assigned to the camera's Preset white balance settings are incapable of accounting for the variability of real world lighting conditions.

Setting a Custom White Balance before you begin shooting remains the most reliable way to consistently reproduce accurate, balanced color in digital cameras.

Set Your White Balance in Only 10-15 Seconds to get Great Color

No special software and no post processing is required to set a white balance with the ExpoDisc.

The ExpoDisc is faster and easier-to-use than old school photography gray cards and color calibration targets. To set your white balance with the ExpoDisc, you only need to cover the lens with it long enough to capture a single exposure. This process is typically much quicker than placing a gray card or target in your scene and then taking a reflective reading of the target from a distance.

When not in use, the ExpoDisc is small enough, and tough enough to simply carry around in your pocket.

We Individually Calibrate Each ExpoDisc for Neutrality

It’s important to use a calibrated reference tool like the ExpoDisc when setting your custom white balance because using a white balance tool that isn’t neutral across the visible spectrum will not provide your camera with an accurate representation of the color of light illuminating your subject. This will cause your camera to compensate in ways that will result in unbalanced color and unwanted color casts. Only a truly neutral white balance tool like the ExpoDisc will produce consistently accurate color balance in your images.

We developed the original white balance filter and have been building ExpoDiscs by hand for over 20 years. Every ExpoDisc is assembled in the USA using our proprietary calibration process using custom materials to ensure it transmits light evenly across the visible spectrum.
