NiSi 49mm HUC IR ND64 (1.8) 6 級減光鏡

Finally got that smooth waterfall effect I’ve been chasing—the 6-stop reduction is just right even in harsh midday sun. The glass feels solid, and I didn’t notice any weird color cast in my shots.

This filter cuts glare on my 70-200mm beautifully, letting me get silky waterfall shots even in midday sun. It's sharp with no visible color cast, and the slim profile doesn't cause any vignetting.

After struggling with overexposed waterfalls for weeks, this filter cuts exactly six stops and my shutter speeds finally dropped to where they need to be. The glass is crystal clear with zero color cast in my test shots.
