Same with snow scenes, by the way. Shadows on sunlit snow landscapes are intensively blue.
Birna, in the days of film, did you ever use the Skylight 1A filter to reduce the blue shadows in the vast Nordic world of snow scenes?
The few times I got to shoot sunlit snow scenes on film (typically Kodachrome 64, Ektachrome 64) the blue shadows were, of course, in evidence. I found that the once-ubiquitous Skylight 1A filter would substantially reduce the blueness of the shadows in those scenes...on film.
Much later I tried a 1A filter on digital, and it seemed to do nothing against the blueness of the shadows.
