NiSi Cinema 4×5.65吋 Nano IRND 軟邊漸變濾鏡 0.3（1級）

Finally a soft grad that doesn't introduce a color cast into my highlights. The gradual transition on this 1-stop filter is so subtle I can leave it on for most of a shoot without worrying about an obvious line.

Used this on a seascape where the sky was two stops brighter than the foreground, and it balanced everything out without leaving a harsh line. The 1-stop reduction is subtle but exactly what I needed for that shot.

The soft-edge gradient is subtle enough that it doesn’t leave a harsh line across the frame, even with a wide lens. It cuts about a stop of sky brightness without messing with the color balance. Only wish it came in a slightly larger size for my matte box.
