I got this Cloth-Clip ND Filter Lens from DCKina. What I want to show you is how it works, because it’s just like using a Circular Polarize Filter (CPL). The filter spins around just like a polarizer filter. There’s a good reason the filter spins around. I’ll show you in a video I did with this filter.
This is what you get in the box, when you get one of these filters,cloth-clip, screwed on filter and micro cloth carrying pouch.
In the video, I show you what the filter looks like and how you clip it on your iPhone. This filter works with Android and Windows Phone. You noticed that when I turn the circular filter. You can see how the filtration works for the ND. The same things works with Circular Polorizer. You keep turning the filter until you find a filtration you like. This how these filters work. So if you slap it on without turning the wheel, you might get some filtration or you might not. You have to turn the wheel to make the filter work. Yes, I wanted to point out I made the same mistake too. I didn’t turn the wheel either. I hope this helps and clear things up. If you have any questions, please leave comments. Have a great day and see you soon !!!
