I think the most attractive thing in the person is when they are absorbing an experience of a moment without any awareness of being watched. The experience can be a thought, feeling, or focus but it is almost overwhelming, a state of so powerfully living the moment that they have no consciousness of it happening.
This state is exceptionally even more powerful when the subject is a beautiful woman. She often has the curse of being an object of appreciation that is hard to not be aware of. Georgina Leahy drove to my cabin in the mountains at a time when life-changing things happen, it was an honor that she came to me to make a beautiful project.
The title Unbearable Lightness of Being pretty much says it all.
