Sometimes using natural light can give your footage the look you're trying to achieve, or when filming large animals that you cannot get up close to either because you wouldn't dare or you won't be able to get their enormous body in your LCD. The Bonica Underwater Color Filter will fit the Bonica Snapper HDDV Housing. The filter alters the green color of cold fresh water to give it a rich, natural tone. It also enhances the contrast of underwater video and photographs. The filter works exceptionally well in shallow depths up to 60'
