Mountain scenes are very difficult to photograph. The very size of them defeats the use of the most interesting light of the day – early morning and evening – unless you happen to be lucky and in a good place. Their distance from the camera adds haze and blue cast to the image, effectively de-contrasting the more faraway images.
This shot was taken in a valley in Waterton Lakes National Park. I was in shadow, as was most of the foreground. Only the peaks of the far mountains were in direct sunlight. To make anything out of this image, I had to use the Photoshop 'Multiply' blending option (as described here) to sharpen up the peaks.
I debated lightening up the foreground more, but this was pretty much as it was. Of course, as always, this picture is no substitute for being there!
