White Balancing

I've been enjoying getting to work early and experimenting with the sunrise.

This time, I changed the white balance; I'm not sure what to though. I basically pointed the lens a little above the sun to 'evaluate white balance' and it created a cool greeny/yellow effect.

The camera did most of the work here with a little shadow enhancement in Picasa.
