I wanted to write an entry on lighting techniques and how to give a painting atmosphere.

Anyone remember Bryce 3D? Digital landscape generation program from the 90's. It looks really dated now, but it taught me a ton about colour and light. It's a great sandbox for trying out atmospheric effects, because it breaks everything down into a few simple settings.

* Sun colour
* Ambient colour
* Distance haze
* Ground fog

( More, and lots of example pics )

Let me know if there's anything here that doesn't make sense! Or if you have any questions or anything.
