Split Light - by Josh
(Slim a round face)

Rembrandt Light or 3/4 - by Josh
(noble light for a writer or dignitary)

Loop - by Josh
(bright, happy, universal light. if in doubt use a loop)

Butterfly - by Josh
(very advanced difficult to achieve, sculpts round faces by accentuating cheekbones)

Short or Narrow Light - by Josh
(Roksana asked about film noir light last week
and this is in the direction of that intent.
Most of your subject is lit darkly with low light
and shape is defined by minimally lighting 
edges.)

Broad Light - by Josh
(widens thin faces)

Rembrandt - by Josh
