Lee Filters ND9GS100x150U2 Neutral Density Graduated Soft Edge Filter 100x150mm

For photographers who need to tame high-contrast scenes without stacking multiple filters, the Lee Filters ND9GS100x150U2 offers a 3-stop soft-edge graduated neutral density solution in a single 100x150mm resin panel. Unlike screw-in grads that force a fixed horizon line, this rectangular filter slides freely in a 100mm holder, letting you position the transition exactly where the bright sky meets the darker foreground.

Highlights

• 3-stop (0.9 optical density) light reduction for balancing bright skies with shaded landscapes
• Soft-edge gradation blends seamlessly, ideal for uneven horizons, trees, and architecture
• Rectangular 100x150mm format fits Lee Filters 100mm system holders and most slot-in systems
• High-quality optical resin construction delivers neutral colour fidelity without unwanted casts
• 2mm thickness ensures rigidity while remaining compatible with standard filter slots

In daily use

Slide the ND9GS100x150U2 into your holder and align the soft transition with the brightest part of the frame. The 3-stop density pulls back overexposed skies just enough to retain cloud detail and colour, while the clear lower portion leaves your foreground exposure untouched. Because the edge is soft, you can use it on scenes with irregular horizons—mountain ridges, city skylines, or forest edges—without a visible line. The neutral resin keeps colour casts at bay, so your white balance stays true. Whether you shoot landscapes, seascapes, or architectural exteriors, this filter helps you capture the full dynamic range in one shot.
