CG Arena offers this lighting tutorial:
"When it comes to lighting a 3D-scene, the light-setup can either make or
break the scene’s believability and realism. Many artists lack the knowledge of
lighting techniques. There are three concerns you have to consider during your
lighting-setup: Is there enough light? Is the light source believable? And, how
does the lighting affect the mood of the scene? In this tutorial, we will
illuminate the scene with the help of one light source and one HDRI. This is a
step by step tutorial, with images to grasp the general workflow idea
easily."
