Surreal and spectacular. I like the shapes of the clouds.

By the way, is it the moon in the sky?

beautiful!  here in the netherlands i only saw this kind of snowlandscape once.
You remind me i also have this lens ... a later 1985 type.
Do i understand you use a filter that cuts at 715nmeter - so only Red and short IR passes through?

correct, the camera has been modified and the UV/IR cut filter has been replaced with an RG715 long pass which passes some red and infrared up to around 1000 nm or so. I swapped the red and blue channels in photoshop giving the illusion of a blue sky. essentially this is an intensity map of reflective infrared so that material in the scene that is highly infrared reflective is white and materials infrared absorbing are black. in addition to absorption in water there is less penetration so the reflections here are more pronounced.

the snow-like effect is illusory and so is the false color blue sky.   the phenomenology is genuinely reflective infrared.

Good result.

I like this a lot.
Your explanation is a bug help, too, as I couldn't believe all the "snow" this winter.
