IR Mountains

[guppiecat]

The interesting thing here is not that snow reflects infrared light so well, but that clouds reflect exactly the same amount.

In visible light, when shooting from the air, clouds make shadows on the ground, but there’s enough light that makes it through the clouds and, presumably, bounces between the earth, off the clouds, and back down, that you can still see the ground in the shadow. This does not occur in infrared. I do not know if that is due to the narrow band I was shooting in or if there’s something else going on.

Still, quite interesting.
