NiSi 100x150mm Nano IR 소프트 그라데이션 ND4 (0.6) 2스탑

First used it on a landscape with a dark foreground and bright clouds, and the exposure balanced almost perfectly without any colour shift. The optical glass keeps the details crisp even when I stack it with another filter.

Used this on a landscape shot with a tree line jutting into the sky, and the exposure transition is incredibly smooth. The optical glass kept everything sharp with zero color cast, exactly what I needed for a balanced sky.

The filter does exactly what it says—no color cast and it balances the sky with foreground trees perfectly, though I wish the glass came with a protective case for storage. It’s sharp and water-resistant, which is a nice bonus for outdoor shoots.
