 The ExpoDisc is far easier to use than any gray card, white card or calibration target. 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.
Each ExpoDisc is constructed of carefully selected and matched optical grade materials encased in durable anodized aluminum filter mounts. ExpoDisc Neutral White Balance Filters are calibrated to strict tolerances of color neutrality and light transmission. Every ExpoDisc filter shipped is individually tested by transmission densitometer for 18% light transmission and neutrality in the visible spectrum (400nm to 700nm). The ExpoDisc's 18% light transmission allows the ExpoDisc to be used as an incident ambient exposure tool (as you would with an 18% gray card), as well as for white balance.
The ExpoDisc is suitable for use with any digital SLR and digital video camera with a white balance function. ExpoDisc round filters are available with quick pressure release mounts in the following standard sizes: 52mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm, and 95mm.
ExpoDiscs are assembled and tested in the U.S.A. Please help support this site by buying your ExpoImaging 95mm ExpoDisc Neutral White Balance Filter or other gear from one of our sponsors: B&H, Ritz. | Manufacturer: | ExpoImaging | | Model: | 95mm ExpoDisc Neutral White Balance Filter |
