Here is a photo of the Bavarian Alps taken at mid-day. Basically this is inherently a bad idea, but I was there at 12 and so did not have an option. Or had an option to not take a photo.
Anyway, bit more about processing here. Again, I have tried to keep the sky as subtle as possible while allowing the focus to be on the mountain range. There is no addition of Hue or extra saturation.
