I am a photographer who shoots both digital and analogue. Sometimes I really want to give my black and white photos a moody look that is hard to achieve with digital photos (at least for me). These filters create just enough diffusion to soften the skin, provide a slight halo effect, and enhance the mood of a foggy scene.

There are two different thicknesses in this package - 1/8 and 1/4. They are screwed together upon receipt and both placed in a small plastic container. They were pretty tight together but were easy to separate with a pair of filter wrenches. When screwed into a lens or a quality step-up ring, they screwed on easily without binding and were easy to remove even when screwed on tightly. These filters did not produce a color cast.

The effects of the 1/8 power filter are very subtle, and the 1/4 power filter creates more of the look I'm looking for. You can stack these filters to get even more diffusion, but that's probably not a good idea in bright sunlight as it's likely to result in stray light caused by light reflecting back and forth between the filters.

I was impressed with K&F Concepts' overall quality and aggressive pricing strategy. Every time I picked up one of their products it was better than my previous purchase. If you want to add a little more diffusion to your photos or videos, these filters should definitely be on your list of possibilities.
