Different Lighting Techniques

What Is Short Light?

Short light is type of studio lighting setup, where the face side which is further from the camera gets the main light. see the diagram for details. In this type of lighting setup, the side of the face which is toward the camera gets less light then the side facing away form the camera. The effect you get when using this lighting setup is a thin face, this is why it is good to photograph fat (or chubby) people with a short light setup.

Diagram 1 - Short Light

Let's look at a picture of a friend of mine - Winnie the poo. Looks like Winnie had allot of honey and he is quite chubby. The flash is set up to my right, and Winnie is looking to his left. This make his face look a bit thinner than what they really are. Short light is very useful in portrait photography, as it gives drama to the subject. (Short light setup also stresses skin wrinkles, to create even more drama for older people)

What Is Broad Light?

Broad light is just the opposite of Short light. In the Broad Light setup, THe side that is getting the most light is the side turning towards the camera. This setup is less commonly used for portraits as it tends to make people look chubby. See the diagram for setup.

Diagram 2 - Broad Light

Lets look at Winnie again. This picture was taken at the same focal length (135mm with 1.5 crop factor D70's sensor). This time Winnie looks very chubby. Oh Winnie! what have you been eating? Also note how the picture looks a bit flatter. There are not allot of light and shade plays.

For both types of light you can use a fill light at the opposite side to the main light, or do as I did and use a reflector at 45 deg. (see diagrams).
Conclusion:

Light Type	Side to Get Most Light	Chubbiness	Wrinkles
Short Light	Away From Camera	Reduce	Intensify
Broad Light	Facing Camera	Increase	Reduce

Short Lighting

Short lighting illuminates the part of the face that is not facing directly at the camera. In Figure Z, we can see that the side of the face facing the camera is in the shadow side. Short lighting often is the preferred light positioning for most portraits especially for rounder faces or faces less defined facial features.

Putting the shadow side of the face closer to the camera narrows down the face and works well for majority of subjects except those with long or thin faces.

Broad Lighting

Broad lighting is the opposite of short lighting where the lit portion of the face faces the front of the camera. Showing the lit portion of the face directly at the camera broadens the face as it illuminates majority of the subject’s face instead of hiding it in the shadows.

While not as popular as short lighting, broad lighting can be used effectively with thinner faces and can make subjects such as the elderly look more radiant and lively. Broad lighting is a “cheerful” light position that portrays openness and excitement.
