Balanced exposure for landscape photography

The Lee Filters 0.9 Graduated ND Filter Medium Edge 100x150mm Resin is a rectangular resin filter designed for photographers who need to balance bright skies with darker foregrounds in a single frame. Its graduated construction transitions from clear to neutral density, making it suitable for both professional and enthusiast landscape work.

Three stops of density with a medium transition

This filter provides a density of .9, equivalent to three stops of light reduction across the graduated portion. The medium edge transition sits between soft and hard options, offering versatility for horizons that are neither perfectly flat nor distinctly broken. It covers the 100x150mm format used by many square-filter systems.

Compatibility limited to 100mm filter holders

The filter fits standard 100mm-wide filter holders and is confirmed compatible with the Nisi V5 Pro system. Photographers using smaller circular screw-in filters or holders narrower than 100mm cannot use this filter without an adapter, which is not included.

Questions about this item

Will the 100x150mm resin filter fit in my existing Lee 100mm filter holder?

Yes, the 100mm width matches the standard Lee 100mm filter system, so it slides into the same holder you already use for other 100mm filters.

How can I verify the 0.9 density is giving the correct three-stop reduction after mounting?

Meter a bright sky through the clear section, then meter through the graduated section; the exposure difference should be three stops, confirming the 0.9 density is working as intended.

Does the package include a filter pouch or do I need to buy one separately?

The filter ships alone; a protective pouch or wallet for the 100x150mm resin sheet is not included and must be purchased separately.
