Dorr DHG 中性密度 ND3.0 1000x 濾鏡 37mm

This filter really nailed the 10-stop light reduction for my long exposure shots of the river. The glass is so clear and sharp that I didn’t notice any color cast ruining the photo.

I was able to take a 1/1000s shutter speed down to a full 1 second handheld—that 10-stop power is no joke. The glass doesn’t introduce any weird color cast, which made editing in post so much easier.

Finally got smooth, silky waterfall shots without having to stack filters. The glass doesn’t add any weird color cast to my images, and the threading on the 37mm is precise enough not to bind. It’s turned my daytime streams into dreamy long exposures with zero hassle.
