Square Graduated ND16 Filter

The Urth 75x100mm Square Soft Graduated ND16 4-Stop Filter Plus+ is a square lens filter designed for landscape photographers who need to balance bright skies with darker foregrounds. It reduces exposure by four stops at the graduated edge and fades to clear for natural blending.

4-Stop Density With Soft Graduation

The filter blocks 16 times the light at its darkest section using a soft transition that suits uneven horizons such as mountains or treelines. It handles high-contrast daylight scenes comfortably but offers no additional density for extreme bright conditions.

German B270 Glass With 20-Layer Nano-Coating

Built from German B270 SCHOTT optical glass, the filter uses 20 nano-coating layers to maintain consistent light transmission and resist water, oil and scratches. The coating makes cleaning straightforward during field use.

Questions about this item

Will the 75x100mm size fit the filter holder I already use?

The filter measures 75 by 100 millimetres, matching the standard square format used by most common filter-holder systems.

How can I confirm the 4-stop density is performing correctly after mounting?

Meter the bright area through the dark end and the clear area through the transparent end; the difference should read four full stops.

Does the package include a holder or pouch, or must I buy them separately?

Only the glass filter with its 20-layer nano-coating is supplied; a compatible holder and any protective pouch are sold separately.
