Both are great. And I agree with the earlier comment that the photographers are to be commended for using restraint with their manipulation.
Honeyset's work is especially interesting to me, as I seem to have a hard time getting fog to appear interesting in any way in my work. It dulls for me, where as it seems to brighten for him. Maybe there's a technique like what Les described for foliage earlier. Any thoughts?
Anyway, thanks for the links.
