Admittedly, I have never used a Black Diffusion filter before so this was a bit of a learning experience. The filters themselves come well packaged in a nice plastic case to protect them. They simply screw onto the end of your lens. The filters have nice grips to help enable you to put them on and take them off. There are also a few lens cleaning cloths included.

These filters fit easily screwed onto my Canon EF lenses. I initially tried a simple portrait shot before and after. The after image was slightly softened and some minor reflective glare was reduced to nearly nothing. I liked my After shot better than my Before shot in this case. However, it is important to note that the results you get will vary depending on your lighting.

Next, I set up a shot with a light source in the background. The result was a bit surprising as I got a bit of a halo effect when using the filter.

To me, the effects of this filter may be subtle or they may be more pronounced and that will depend on how you set up your shot and where the light source is. I found these filters to be a pleasant surprise. For me, there will be a little bit of a learning curve to determine when I might want to use these.

This is a nice quality filter set to add some interesting softening effects to your pictures.
