In a rum bar somewhere in southern Barbados, the owner was mixing drinks for us to try. He was standing behind the bar under the shade of the roof, but a large opening in front of him softly lit one side of his face with daylight.
On a cloudless afternoon the sunlight is often too harsh, making it pretty tough to photograph faces. A quick fix (and a very good one) is to keep your model in the shade. But while shooting in sunlight will give you too much contrast, the shade could leave you with too little. Even if your model is in the shade, there’ll always be more light flowing in from another direction. If you’re standing in a tunnel or archway, the entrance will be your source of light. If there’s a bright wall hit by sunlight close to where you’re standing, it will reflect brightness your way. Look around, where is the light coming from?
