A narrow light source does the opposite. This is because, with a broad source, light rays hit your subject from more directions, which tends to fill in shadows and give more even illumination to the scene.

Tip: Position a portrait subject near a large, bright window that does not receive direct sunlight. It makes for a no-cost softbox— no studio equipment necessary.
