Found out later that a pro photographer in Philadelphia shoots this kind of image for clients.
Note: I originally posted these images on my "Tumblr" blog site, but I moved them here, because I like the blogging features available from Google. I think Tumblr behaves more as a social network site, like Facebook, and blogging is secondary.
My tumblr blog is at http://www.tumblr.com/blog/javamind
I'll be moving posts from tumblr here over time.
