NiSi 180x180mm Nano IR ND1000 (3.0) 10級減光濾鏡

I’ve been trying to get silky smooth cloud movement in bright midday light, and this filter finally lets me shoot 30-second exposures without blowing out the sky. The 180mm square size fits my holder perfectly, and the glass is crystal clear with no color cast that I can see.

Shot a few long-exposure seascapes with this square filter and the nano coating really cuts down on those pesky reflections I used to get. It's a solid piece of glass that slides into the holder smoothly, and the 10-stop density gave me butter-smooth water in broad daylight without any color cast.

The 10-stop density is spot-on for smoothing out waterfalls even in harsh midday light, and the 180mm square size fits my holder without any light leaks. I stacked it with a polarizer once and still got clean, neutral colors straight out of camera.
