My wife's worse than a skittish horse! Produce a camera, and she all but hides in a cupboard!Every now and again, my wife will challenge me. She'll walk into a room I'm in and say, "I want you to take a portrait of me and you have 10 minutes to pick the camera, lens and lighting you want".
I have managed to sneak a few nice photos of her over our 40+ years of married life. She would never forgive me if I were to post any of them here. She has always been shy that way.
