Ideal for digital photography, the EzyBalance enables setting of accurate grey balance and white point. Use it to set accurate exposure at the point of taking a picture, or take a reference shot with the Ezybalance included in the picture, and use the eyedropper tool in Photoshop to adjust the shot later. The same setting can then be applied to all photos taken under the same lighting conditions. It has an 18% reflectance surface and is available in three sizes.
