Have you guys heard of Gizmodo's recent Day & Night photo challenge? I'm still trying to figure out how, exactly, this was accomplished (other than the obvious shooting in the same spot at multiple times of day) but I simply love the effect. I first heard about this technique when I read an article recently about Stephen Wilkes. He has some of the best Day to Night photos I've seen:
Not long after reading about Wilkes' project, I saw the photos from Gizmodo's competition. Here are a few of my faves:
I get what to do in actually taking the photos but I can't figure out the post-processing techniques. Granted, I'm not the most advanced PhotoShop user but I can usually figure different techniques out after a few tries. This stumped me though. Any ideas?
