If you want better portraits, you need to start with the pose. And here’s a simple trick that will improve most portraiture immediately.
Ask the subject of the photo to dip one shoulder closer to the camera. It immediately turns the body in a more flattering way and avoids the number one sin of portrait posing, i.e., square shoulders.
That’s it. Simple and effective. Turn one shoulder to the camera and dip. Now you have a flattering pose.
