I love how you managed to get the face and eyes in sharp focus and her neck and shoulders slightly out of focus, even though they are in the same plane. I'm assuming that this was some sort of digital processing as I can't see how it would be accomplished optically unless you did it in the printing process by physically moving that part of the negative or the paper receiving the imprint so that it is out of focus when being printed.
I was bobbing through some Audrey Hep pics. One of her pictures struck me and I thought of this one. The deep defined eyes and even the hair, though Irene is platinum, still Audliciouse. I'm not trying to compare. Irene is painfully beautifull.
