In a world where we chase the ultimate sharpness in images and video, diffusion filters are a fun getaway from that rat race. This particular filter is, in my opinion, fairly "low power" in most situations, so you can safely add it without causing an overpowering effect like many other filters, especially in the budget section. This can be used for portraits to give a slight glowing effect and soften up some of that sharpness while maintaining image detail, or for landscapes to add some glow to any light sources in the scene, along with any variety of scenarios you might come up with. If you have the time, I'd recommend trying it out any chance you have and seeing if you like what it adds to the image. These filters are very subjective and what may work for one person may not for another, and in reverse as well of course.

I found this to be most effective when there is some contrast and drama to the light. In the flat midday sun, it was actually difficult in my case to find any difference at all other than some mild softening of the image. However, in my night test, it added a wonderful glow to the various light sources, making the image much more appealing and less harsh.

One of the best things I noted about this filter is what it DIDN'T do. I didn't notice any color cast or discoloration caused by this filter. Many other filters struggle with this issue but in anything from midday sun to nighttime darkness, I didn't notice any color shifting (and to clarify, I'm reviewing these on my calibrated BenQ monitor).

Two side notes to mention:

I now own several different items from K&F and I've been increasingly impressed with this brand of photography products. This filter is definitely going in the camera bag and I will be trying it out as often as possible.

Additionally, this filter is packaged in one of the nicest hard cases I've seen. The smoke gray circular case stands amount amongst a sea of white square cases for my other filters, and includes a really neat rubber "mount" inside to hold a variety of filter sizes without it flopping around in the case.
