So with linear, the polarization is set and you don't have to turn a ring, right?
Whereas with circular, I have to turn the ring and see through the lens when I've
found the amount of contrast I want.
Am I right?
(Sorry, I have used filters before and am not a dullard, but it is pre-caffeine and I
am just trying to get my head around this clearly!)
So why would I bother getting a circular if all I'm going to do is turn it to the
point of contrast that I would instantly get when attaching a linear?
That's what you meant, isn't it Mrrd?
