Here's a weather experiment -- I hope to get a handle on IR in all kinds of conditions -- taken across the holler during a moderate rain shower. It seems, though I cannot prove it, that infrared cuts through the clouds and rain better than visible light does. The far hillside was as dark as the foreground in visible light, but seems sunlit in the picture. Strange, huh.
I actually had to bring the highlights down a bit in post.
I have to say -- some of these look like medieval Japanese wall hangings, don't they.
