One point lighting is a single source of light, which creates a very natural , sometimes dramatic look that will draw people’s attention to the single lighted person or surface. The use of only one light creates dark shadows which frame the face.
Chiaroscuro is a type of one point photography which is the use of strong contrasts between light and dark, usually bold contrasts affecting a whole composition.

This is my favourite image out of the shoot. I like the contrast of the shadows on her face and how the shadow splits her face in half , which creates a mystery. To create these images I used one point lighting, which created the shadow formed on her face.
