I think there is a question of what is meant when people keep trying to tell people in essence "what you're enjoying isn't true" and attach some sort of "the colors don't change" comment with it.. and a question of what is meant when people keep saying they are enjoying the benefits of using x y or z filter.
First, if people weren't noticing a difference in their photos and output, we probably wouldn't have responded to the opening post to say that yes, for us, we are using them and finding great benefit.
Secondly, if a pixel color value changes, then that photo's color is, indeed, affected by said filter, no matter how eloquently or forcefully you can say it isn't.
There are plenty of people who really appreciate the range of effects possible by using various filters, from ND to Polarized and others, and lenses that have multiple properties. It seems funny to me that people would argue against that.
For what it's worth, I'm a fairly non-versed photographer, and the camera on my
Mavic Pro 2 is the most amazing camera I've ever used, and I've found this community to be mostly helpful, though there are some who insist that others see things their way about this or that.. just ignore them, they'll eventually give up.
