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.
PMMA – Resin used in the Benro Universal square filter range is a hard-wearing shock-resistant material perfectly suited to heavy extended use. A cost-effective alternative to glass filters, perfect for photographers that are keen to advance their photographic skills. Resin filters are generally more susceptible to scratches and marks than glass filters, but can be dropped or bent without breaking.
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.
ADT – Advanced dyeing technology reduces the issues of colour shift found with other resin filters. Benro Universal Series filters guarantee Low Colour Shift through digital calculation comparisons for improved neutrality of resin graduation coatings.
WMC – Waterproof Multi-layered Coating is applied to filter surfaces to create an ultra-smooth, hardened anti-scratch finish. The clear coating will repel dirt and liquids and will also allow for quick easy cleaning of the filter surface.
Precise Graduation – Benro Universal Series filters offer an optimised gradient region for ultimate control of light and dark. Graduation coating is extended to ensure best coverage balance is in the centre of the filter.
