TIP #1 -- How To Eliminate A Double Chin
Eliminating double chins or excess skin under the chin is simple.
When you’re the photographer, all you have to do is raise the camera – get up higher so you see less of your subject’s neck.
When you’re the model, you have two options:
1) Tilt your chin upward and lean forward. This will stretch the skin under the chin.
2) Position yourself (or your model) with one shoulder away from the camera, while turning the head to look back at the camera. This will slim down body mass. It’ll also flex muscles in the neck, making it appear more slim and youthful.
