For: Female & Male Models
Are you having trouble producing a really intense, dramatic stare? Then try this awesome tip from fellow model/actor (and photographer!) Breanna Baker (who took the headshot image of me below):
Concentrate on trying to read what the writing on the camera around the lense is. The key is to not squint but instead hold a steady and intense gaze into the camera as if you're in deep thought.
The result: a really great dramatic shot that doesn't take a lot of effort to produce.
