Sometimes a woman applies and I am not sure if I'd like to have her as a model or not. When I think "well maybe, who knows..." I ask her to undress to take some test shots.
Now the woman you can see in this series was extremely interested in a session, she even brought different clothes with her. And she was not only interested, she was very active, to say it somehow.
I mean, I am a man, and her activity was really very convincing... so the test photos turned into quite more than some quick shots. It stayed with this one and only unprepared session, though...
