John, when you show us "Moments" like this; I feel my spirits rise and my whole outlook for the remainder of the day is improved! I would love to know what you said (or did?) that elicited that beautiful smile when you walked in and captured her getting ready. She is, obviously, very happy and comfortable being there and sharing her wonderful beauty with you and your camera! Bravo, again, good Sir!!!
I don't think anything special is exchanged .. in my view, it's a mixture of shyness and complicity .. there is not much shyness when posing, but being oneself is always more self conscious .. : -). Thank you for passing by my friend ..
