ExpoImaging has introduced the ExpoDisc 2.0 Professional White Balance Filter for digital cameras. The original ExpoDisc Professional White Balance Filter was available in separate Neutral and Portrait (warming) versions. ExpoDisc 2.0 combines these versions into a single tool. ExpoDisc 2.0 includes two levels of custom warming gels which can be inserted into recesses on the face of the ExpoDisc, enabling photographers to add varying degrees of warmth for pleasing skin tones. The ExpoDisc 2.0 will initially be available in a 77mm filter size with more sizes to follow. As with the original ExpoDisc, a larger ExpoDisc 2.0 can be used with smaller filter size lenses by simply holding the ExpoDisc 2.0 over the lens during the white balance setting procedure. The ExpoDisc 2.0 77mm White Balance Filter retails for $49.95.
