Well I do carry a blue filter when I want to get open shadows and exaggerate the effects of atmosphere and distance. The landscape masters of the 19th prior
to panchromatic film used to do this wonderfully, since all their film saw was blue. Somehow ever since the era of AA etc, everybody forgot about it and it somehow became "wrong". But I carry a red filter too. And it's amazing how much smoke you can cut through with a red. One brief trip I climbed above most of
the damned forest fire smoke in Sequoia and was camped under some crags up on Mt Siliman where the air was at least breathable (except for inhaling a mosquito now and then). But I was tinkering with shots of the crags, first with silhouettes still largely obscured by smoke, then through the red filter. One of the big enlargements there was a golden eagle perched right on the spiky summit of one of the crags. I had no idea it was there. I could hardly even see the top of the crag when I took the shot. Dumb luck, I guess.
