Hard Grad GND filters are used when there is a clear (flat) horizon line separation between sky and foreground, and when there is also an obvious exposure difference between the two. The Hard Grad GND filter’s primary role is to balance the exposure difference between sky and foreground.
HD – High Definition optical technology. Precisely ground optical glass ensures that surfaces are parallel, allowing the light entering the lens through the filter to do so in a straight line, maximizing image and light quality.
WMC – Waterproof Multi-layered Coating is applied to filter surfaces to create an ultra-smooth, anti-scratch finish. The clear coating will repel dirt and liquids and will also allow for quick easy cleaning of the filter surface.
ULCA – Ultra Low Chromatic Aberration coating prevents light reflection and improves light transmission, resulting in better quality images.
Anti-IR – This advanced coating technology blocks infra-red and ultra violet light, both of which can affect image quality negatively. IR and UV will normally be seen as a bluish or orange tone across your images.
