A new filter from K&F Concept, this time an unusual one a Black Mist/Diffusion filter, combined with a Variable ND. They have a few different variations, I look at the 1/4 Mist with the ND 2-400 range.

In the video I show you the filter (photo and video samples), and demonstrate the effects you can get from it (daylight and at night/portraits etc). The 1/4 Mist is a medium effect (lower numbers are stronger 1/2 and 1 etc), with the 2-400 VND giving you around 1-9 stops of light reduction helping you get slower shutter speeds, or if using faster apertures in daylight.
