I don't shoot portraits as much as I used to, but thought these would be nice to add a little something extra - obviously with the need to have lights in the shot too.

In my quick testing, I had a really hard time seeing the effect. I was just playing with them around the house, so I lit a candle and then pointed them at some other lights too. They definitely need a light source in frame and the brighter the better. Using the 4-star filter gave me no results that I could tell at all. The 6 and 8 were considerably better, but were faint.

I was able to see the effect better just looking through the filter myself than I could when the filter was on the camera. I tried different exposure levels to see if there was a sweet spot, but could not distinguish one.

These filters are fairly well made. I do wish they were magnetic so that I could use them with my K&F magnetic filter set, but that's a minor thing. I did find that the 4 star turned better than the 6 or 8, which made adjustment easier, if I could see the effect. I did have one that was stuck on my lens for a while. I had to really work with it before I could finally get it off. Maybe I tightened it too much, I'm not sure.

The storage case is nice, although it doesn't have any way to attach to a bag or a belt. The case with the K&F magnetic filter set has a belt loop as well as I ring that I use with a carabiner clip to attach to my bag.

The inclusion of micro fiber cloths is nice. You can never have too many of these cloths and, while these are not that large, they are a good addition to my collection.
