ExpoDisc is Hand Calibrated in the USA
The ExpoDisc is tested by hand on a transmission spectrophotometer and individually adjusted using custom formulated materials to ensure an 18% total light transmission across the visible spectrum.  This neutrality is important because using a non-neutral tool for white balance can actually add undesirable color casts to images.  Each ExpoDisc 2.0 includes a quality control card to certify its neutrality.
