I've never quite understood the idea of using polarizers all the time -- see what they do to blue sea and lakes, for a start. Yes, they darken some blue skies a bit. So?
Years ago they helped add saturation to low-sat films (and almost all films were low-sat in those days) but RF lenses are generally so much contrastier than SLR that I remember one reviewer criticizing my '35mm Panorama' for its 'over-saturated, over-polarized' images. I didn't worry because he clearly hadn't read the book. If he had, he'd have seen that I said that one problem with the Leicas I used was that they couldn't easily be used with polarizers, so I didn't...
I use polas in the studio, but almost never elsewhere. I didn't even bother to pack one for my last tour of Central and Eastern Europe in June/July: from home in France via Germany and Austria to Hungary, then Romania, Slovakia, Czech Republic and home, 7200km/4500 miles in a 1973 Land Rover 88.
But we did carry yellow, orange and red for B+W.
Cheers,
Roger
