@PolarPro, maybe you can confirm/clear up my understanding of linear vs. circular polarized filters. I'm new to CP, have used linear for years on my SLR. Never had CP filters ever suggested to me, so I ignored them. I'm just a lightweight hobbyist when it comes to shooting on the ground.
Anyway, I DO understand polarization as an optics concept from the physics aspect. So I thought (wrongly) that CP filters were simply filtering out chirality in one direction and passing the other. As such, rotational orientation was irrelevant, and the Mavic CP filters can just be pushed on with no attention to orientation.
Then I came across this article:
All about Polarizers - Linear and Circular by Bob Atkins, completely throwing out what I thought a photographic CP filter was. In fact, it is NOT a circular polarized filter, but in fact a linear to circular polarization converter. The reasons behind this approach are explained in the article for anyone interested; the key point is that the CP filters from PolarPro are directional, so rotational orientation affects the ability to block linear polarized reflections.
So, basically, treat CP filters the same as LP filters when setting up. Correct?
(aside: After that article explained in more depth and forced me to think about the whole issue in some detail, I realized how meaningless using and
actual CP filter would be for photography)
