The Lastolite EzyBalance Gray Card 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 its 12"
opened round size making it infinitely more convenient and allowing it
to fit into a small bag or pocket.
