From my files. Canon EOS 5D Mark III with my superb although heavy 500 f4 lens, handheld @ f16, 1/1000, ISO 400 with a +0.3 exposure compensation.

Photoshop Auto Colour filter applied, although the sky could be better. Slight Unsharp Mask filter applied.

Very slight crop for composition purposes. Many lens dust bunnies cloned away from the sky as well as tiny snow reflection sparkles.
