Dorr DHG ニュートラルデンシティ ND3.0 1000x フィルター 46mm

Finally got that silky smooth water effect on a river shot. The 10-stop density makes a huge difference in bright afternoon light.

I love that this filter lets me turn a bright sunny scene into smooth, silky water shots without any weird color cast. The 46mm size fits perfectly on my lens, and the 10-stop reduction is exactly what I needed for long exposures during midday.

I wasn't sure if the 1000x factor would be too extreme, but the math works perfectly—turning a 1/1000s shot into a full second is exactly what I needed for smooth water effects.
