I guess the grayness is intentional, but I would like to see a slightly brighter version. Otherwise, it is a lovely example of "less is more".
Thank you for the comments Slobodan. I did overexpose by one stop, and occasionally I go as far 1-1/3. My experience with snow is that when I overexpose as is often recommended, I find the whites look too white, almost burned out, for my taste. The highlights were also difficult to maintain while maintaining the whiteness of the snow. I find the exception to be when there is a lot of other scenery in the image, like skies, trees and foliage, etc, so that the whites look palatable. I will say that I used the rear camera screen to judge the exposure and not the histogram, and I did not bracket. Maybe should have. But it could just be me preferring it this way.
