The EzyBalance Grey/White Card 12 is a revolutionary tool for adjusting color balance and exposure settings in both film and digital cameras and camcorders. It provides accurate color rendition by offering a pure white surface where the camera can perform a white balance check. On its other side, it provides an 18% gray card surface that is suitable for getting the most accurate exposure setting. It is made from high-quality, durable materials and is sewn to a sprung steel rim by using triple row stitch technology.
