split lighting

edge/split lighting only requires one light source, usually the key light (natural lighting can also work). by removing the fill light, a shadow is created on one side of the subjects face. in film, this lighting technique can create a dramatic and mysterious effect.

to achieve split lighting, place the light at a 90 degree angle to the direction your camera is facing. having the light on only one side of your subject will create a split in the middle of the subjects face. one side will be lit up whilst the other will be dark. 

this is my example of split lighting. we placed the key light on the left side of the subject which then created a line directly in the middle of the face. one side is lit whilst the other dark. to get this outcome we didn't use a fill light in order to see the shadows that the key light creates. we turned off the lights to do this so we could achieve a better outcome.
