The aim of this design was to create a low key shot, in which the background was in shadow and the face was ‘lit’.
I took three photographs of the same subject:
- one exposed correctly
- one under-exposed by 3 stops
- one over-exposed by 2 stops
I put the three photographs together in Photoshop in Layers:
- darkest image on the top
- correctly exposed image in the middle
- brightest image at the bottom
Using a Layer Mask on the top (dark) layer, I applied the Brush tool (at 50% opacity) to ‘rub out’ the dark layer in the subject’s face. I finished by reducing the opacity of the top (dark) layer to 80%, to bring back more ‘ambient’ light from the middle layer.
