Rim Lighting effect

By placing the sun behind the object and turning on the fill flash, you will get rim lighting effect see the rim of light that outlines the object. Usually if the fill flash is not turned on, you will get a silhoutte instead (which I will try my hands on when I have the chance). But in this case, the front of the object is bright enough, so I didn't turned on my flash.

This effect works better if the object has magnificent hairstyle (like a fro).
