Use the ExpoDisc to Save Time Editing White Balance in Photos and Video
With the Expodisc 2.0 Professional White Balance Aid you Set white balance, meter for exposure and dust map your sensor with the only calibrated and certified 18% transmission incident light metering filter.
Larger ExpoDisc Sizes Can Be Used with Smaller Lenses
As with the original ExpoDisc, a larger ExpoDisc can be used with smaller filter size lenses by simply holding the ExpoDisc over the lens during the white balance procedure.
ExpoDisc is Hand Calibrated in the USA
The Expodisc 2.0 Professional White Balance Aid 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.
