Art of Blender
The Art of Blender is full of inspiring renderings from Blender artists around the world.
In this Blender 2.5 video tutorial we go through a bit of a lighting exercise by lighting a bust. Using slight variations to a single light rig we are able to achieve three completely different feels to the image. This tutorial covers the use of area lights and the use of three point lighting setups.
