100x150mm Square Reverse Graduated ND8 Filter

This 100x150mm square filter provides a fixed 3-stop light reduction for landscape photographers who need balanced exposures at sunrise and sunset. German B270 SCHOTT optical glass ensures true colour capture across the frame. The reverse graduated design darkens the centre and fades toward the top edge.

20-layer nano-coating limits and protection

A 20-layer nano-coating delivers a consistent transmission curve for accurate light reduction. The coating repels water, oil and scratches to simplify cleaning and extend service life. Standard 100x150mm dimensions fit compatible filter holder systems without vignetting on most wide-angle lenses.

3-stop density suits bright horizons

The ND8 density comfortably handles bright horizon lines during golden hour, preserving highlight detail in the sky while maintaining shadow information in the foreground. It runs out when the dynamic range exceeds three stops, requiring additional filtration or exposure blending techniques for extreme contrast scenes.

Questions about this item

Which filter density should I choose for balanced sunrise shots?

The ND8 3-stop density reduces light by three f-stops across the centre, ideal for equalising bright skies and darker foregrounds at dawn or dusk.

What does the 3-stop reduction do to my exposure in practice?

It lets you use shutter speeds roughly eight times longer or apertures three stops wider without over-exposing the sky, preserving detail in both highlights and shadows.

Will the 100x150mm size fit my existing filter holder?

Yes, the 100x150mm square format matches the standard holder system used by most major brands for landscape photography.
