Novoflex Zebra XL

The control card is a double-sided flexible card made of special plastic with a grey and white anti-reflective coating. The gray area serves as a reference area for exposure measurement (18% reference gray) and the white area allows correct white balance for digital photography. You measure the respective side of the control card with your SLR camera and carry out an exposure measurement or a manual white balance - the camera is already perfectly adjusted to the current lighting conditions and guarantees optimum image results. Novoflex control cards should not be missing in any photo bag.
