I've googled this filter I have, but the definition seems kind of vague as to what it is and when it should be used.
I got it for free, as it was stacked on top of a UV filter, which was on a lens I got. I unstacked to reduce IQ degrading, but my main question is:
What are they used for?
When do you use one?
Does anybody use one?
Thanks
