Put light off the side of the face and hold it up at a 45-degree angle. Watch the shadow of the nose to create a triangle from each side of the eye and the tip of the nose.
2) LOOP LIGHTING
Elongates the face (flatters most faces)
Hold it to the side of the face and move the light a distance so you have a little bit of a loop shadow under the nose.
3) SPLIT LIGHTING
Creates A LOT of drama and flatters the male face because men may have broader noses than women (makes nose look slimmer).
Directly at the side or behind the subject. Hold the light right up to the face so one half of the face is lit and the other half is not.
