It can be tricky, taking photos of your friends.
You're trying to juggle several different aspects -- their desire to look attractive / beautiful, your desire for an interesting photograph (which for me means one that captures something of their personality), their shyness or discomfort with the camera, the light, the setting, the mood, and your own skill level, which always seems inadequate to the task.
Sometimes you get only somber photos -- sometimes only smiling ones.
Sometimes you take a hundred photos to get one good one. Most of the time.
But some people make it easy.
I find this last one the sexiest. Which probably reveals more about me than it does about Susan.
