NiSi 100x150mm Nano IR ソフトグラデーションNDフィルター ND32 (1.5) 5段

I’ve been using this 5-stop soft grad for seascapes, and the nano coating really cuts down on unwanted flare. The color cast is minimal, so I’m not fighting to fix it in post.

Soft graduated transitions are exactly what I needed for harsh sunsets—the darkening fades naturally without a hard line across the frame. The 100x150mm size fits my holder perfectly, and the IR coating keeps colors clean even at 5 stops.

The 5-stop density is perfect for smoothing out bright skies, and I’ve been impressed with how little color shift it introduces. I was worried about a magenta cast, but the Nano IR coating handles it well. It’s a solid tool for getting balanced exposures in one shot.
