Sony A7S II (12 megapixels)
Zeiss Batis 25mm f/2 Distagon

Aperture Series: Blue Dusk Settles on Snowy Lundy Canyon (Sony A7S II)

This series taken under extremely blue light. The amount of correction for the very blue light saw some experimentation—in the end a color temperature of 7000°K was used, leaving the image moderate blue, because even to the naked eye, the scene was dark and bluish.

Blue Dusk Settles on Snowy Lundy Canyon

Sony uncompressed raw format. Sony SteadyShot disabled, all lens corrections disabled in the A7S II except chromatic correction. Uncompressed raw format. No filtration.

Adobe Camera Raw 9.3.1 (520). ACR settings. Camera Profile = Adobe Standard.

The RawDigger info shows a good exposure, though not quite a maximal ETTR exposure; the sensor could have accepted about another stop but regrettably, the Sony histogram function does not make exposure decisions like that clear (ditto for other camera brands).
