1/4 Black Mist Filter

I put the 1/4 black mist filter to work at the 50 Up Circus tech rehearsals, and was pretty stoked on the results. Initially bought for a portrait session, I figured the strong theatrical back light would hit the sweet spot, so I thought that I'd give it a go. Together with the smoke atmosphere, it really added a new dimension and both myself and the cast loved the results, even though it was an F4 lens.

Amazing quality filter

Using this with a Fujifilm Xpro 3 on a 27mm lens, no compromise on quality. The diffusion is smooth and provides a great atmosphere to your shots. Definitely grabbing one for my 50mm lens.

I’ll be back

I ordered the Urth 10% diffusion filter in the hopes of taking a slight edge off of a stunningly sharp, Fujifilm lens, and rendering a more filmic look to my images. A half dozen shots later, I knew that it was mission accomplished. A quality product, wonderfully packaged, at a reasonable price, delivered in a matter of a few days.

Perfect

I’ll be back.
