Lastolite EZ Balance Waterproof Collapsible Light Balancing Disk - Grey, White - 12" is a revolutionary tool ideal for adjusting color balance and exposure settings in both digital and film format cameras, as well as DV cams. The Ezybalance gives accurate color rendition to cameras by providing a pure white surface upon which the camera can perform a white balance.
The reverse side of the Ezybalance provides an 18% gray card surface suitable for adjusting the camera to get the most accurate exposure setting. Conventional methods of exposure control consist of using large gray cumbersome cardboard that is easily stained and over time becomes dog-eared, posing the risk of taking incorrect exposure readings. By design, the Ezybalance folds to just a third of it's 12" opened round size making it infinitely more convenient and allowing it to fit into a small bag or pocket.
