Instructions
Place the subject on the modeling stool and position him so his shoulders are at a 45-degree angle from the camera. Once the shoulders are turned, have the client turn his head so he is looking directly into the camera.
Raise the camera so the subject will have to lift her chin to continue to look directly into the lens. As the client lifts her chin, the double chin will start to reduce.
Position two studio lights, one on each side of your subject, directed toward the subject at 45-degree angles. Raise the lights so they are pointing down toward the subject. Turn on the modeling light and observe how the light falls on your subject. When the lights are raised to the correct height, a slight shadow will appear under the client's face that will further hide the sagging neck. If the sagging neck is still visible, raise the lights a little higher until the shadows hide the neck. Do not use reflectors under the client's face, and if possible have the client wear a dark shirt or sweater that will not reflect light up toward the chin and neck.
