Wow, these are are really great. I have been looking at the Cicada shells around my city, trying to take a decent photo of them, but no luck. I love the other one as well (http://www.durhamtownship.com/portfolio/archives/001375.php)
It may help to live in beautiful surroundings like you, all your photos of Durham look amazing. How do you get the pastel colors? Is that how everything really looks, or is it just something wrong with my eyes?
Amazing! It would have been an impressive shot even if the Cicada was alive, but the fact that it's an empty shell makes this beautiful shot even more impressive. Great work, and a wonderful portfolio!
