مرشح NiSi 72mm Nano IR ND32000 (4.5) 15 Stop

Finally got the silky smooth waterfalls I've been chasing, even under harsh mid-day sun with this 15-stop filter. The Nano coating on the glass made cleaning off sea spray a breeze, and my 2-minute exposures came out tack sharp.

Shot some seascapes at f/11 and this 15-stop filter gave me smooth 45-second exposures even in bright midday sun. The nano coating really cuts down on that color cast I used to fight with cheaper NDs.

I was worried the 15-stop density might be too dark to compose through, but the IR-cut coating keeps the image sharp and neutral even at this extreme strength.
