Alice: Everyone can look amazing! Most people who come to me feel uncomfortable in front of the camera either because of their negative photo experience on daily basis or their lack of confidence. They've never been comfortable posing so they just assume they will never be. But that's not true.
First of all, try standing in front of a mirror and study your best angles, experiment with different poses. This will raise your confidence in front of the camera plus shake away the awkwardness away as you'll know what to do most of the time.
I normally help with some directions, but often just talk with people during the session and keep reminding them of how beautiful they look. This is helpful to everyone that hates having their photos taken because as soon as I start complimenting them, the confidence starts rising and they instantly feel more beautiful, positive and happy. This then translates into equally fantastic photos they’ve never had the chance to get before.
