Over sharpened, I see what you mean. It looks better larger, though, I think. Less sharpy sharp sharp, there.
EDL, yup, that's a road. We drove one of our national tourist roads, road 520, from Sauda to Røldal. Not the most time efficient way, but a really beautiful road. Too narrow for two vehicles very often. If you're in west Norway (Sunnhordaland to be more precise), then you should check this out.
I tried doing monochrome conversions, but I didn't manage one I liked.
