I was looking around on flickr and came across some absolutely STUNNING shots. While also very good in subject matter and composition, the sheer clarity and sharpness and just overall "WOW!" of these pictures is stunning and light years beyond anything I've been able to produce. I was wondering if anyone had any idea what was being done in post processing to achieve this look? I'd love some input and advice! Thanks!
