An lesson with white balance

This is a little lesson in "white balance". This leaves on this tree, in real life, were extremely vibrant in its yellow-green colors, and seemed to jump out against the dim, dull, cloudy sky.

This is a picture with the white balance set to zero. It looks normal and boring, and doesn't capture the vibrancy of the colors.

This is the same tree with the white balance set to -2. It looks like a scary horror movie where someone is going to be murdered. A lot of the color is gone.

This is the same tree with the white balance set to +2. It looks blown out and the colors have also lost their vibrancy because the light takes over.

This is the same tree with the white balance set to +1. It's not perfect, but its better than zero or +2. To get the colors right, you need a little photoshop.
This is the product of 30 seconds of photo-editing. With more time, you could photoshop the sky blue and make it look more like california and less like the a land shrouded in clouds of doom
