To avoid that awkward ack-don't-take-my-picture smile, thinking happy thoughts can go a long way. Pro portrait photographer Allison Temple swears by this trick with her clients. "It sounds kind of silly, but when people are thinking about someone or something they love, you can see it in their eyes and expression. So I tell people to remember a really happy memory or think of a funny story." Plus, it can help you relax and feel more natural in front of the camera.
