The Red Diamond filters feature a shock-and-scratch-resistant design, making them ideally suited to the harsh challenges of outdoor landscape photography. Haida Red Diamond Filters feature an ultra-thin Nano Multicoating that retains superb image sharpness as well as delivering true color with zero color cast. The Red Diamond series is double the strength of a normal glass filter, which provides for a low risk of accidental breakage. An ND Filter provides a solid stop exposure, creating a darkening of the entire image and allowing you photograph with a wider aperture and slower shutter speed. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.
Soft Edge Graduated Neutral Density Filters start clear at the bottom of the filter before transitioning into the Neutral Density effect as it approaches the center and gradually becoming strongest at the top of the filter.
