The Heliopan Bay 6 ND 0.3 Filter is a solid ND filter providing a 1-stop exposure reduction. This 0.3 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.
The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, they offer protection to the filter substrate while helping to keep the glass clean for longer than uncoated glass.
This Heliopan filter is constructed from SCHOTT glass for increased optical clarity and color fidelity. It features a brass filter ring for durability as well as jamming prevention.
