Just to amuse myself, not that you'd really want to do this, but guess how many lights were used in this scene?

Ready?

ZERO.

There are no lights. Just the environment sphere.

It would look better if the image I used was HDR, but for the type of scene I wanted there weren't any.

This is the gray-skinned Apollo. His color is from the environment.
