I was reading a digital photo magazine today and it had a good tip on using a polarizer: bracket. I've used bracketing a lot when I'm unsure on exposure but I've never thought of bracketing the actual polarizer rotation itself. I usually rotate the ring and attempt to gauge the best effect, but I tend to settle on a particular amount and take a single shot.

Taking a few shots with different amounts of polarization is a simple idea that may make a world of difference in the final photo.
