I've seen it and heard people mention that they could take it out in PP but how do you avoid it altogether? And what causes it?

Here you go: http://en.wikipedia.org/wiki/Chromatic_aberration

I find CA show up at the transition between something very bright and something which is darker. So say you are shooting a tree against the sky, if you zoom in on the image and look at the edge of leaves or branches against the sky chances are you will see colour fringing or CA.

Using Canon's own DPP removal of CA is easily carried with a click or two of the mouse. On some of the newest cameras like the 5D3 CA correction can be processed in camera for jpeg's. The new firmware for the 7D now includes CA in camera correction.

Avoiding it is not going to be easy unless you never shoot images which have bright areas, or only use Canon DO lenses.

I wondered why the ball kept getting bigger, then it hit me.
