The Ezybalance 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 other 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 30" folds to about 10" making it infinitely more convenient and allowing it to fit into a small bag. Suitable for all environments, the Ezybalance is made of a high quality, wipe clean surface material, sewn to a sprung steel rim using triple row stitch technology - further ensuring its craftsmanship and durability. The 30" Version is great for every SLR use
