My original idea was to post about polarizing filters, but Gabby beat me to it! :-) After some thought, I decided to post about polarizing filters anyway. One unusual aspect of these filters is that their effect changes as you rotate the filter. They work based on the angle of light in relation to the filter, so when you spin it or pan the camera, the effect changes. (See Gabby's post for more on polarizer effects.)
I have two example photos taken from the deck behind my house. The view is of my family's organic dairy farm (our milk is sold by Organic Valley). I used a polarizer for both, just rotated it for opposite effects (warm vs. cool). Unfortunately, I didn't take a picture without the polarizer. Both pictures were taken with a Canon EOS 10D and Canon EF 16-35/2.8L USM. The metadata for both is f5, 1/100sec., ISO 200, and 35mm.
The only problems with polarizers are that they take a few extra moments to put on your lens, and they decrease the amount of light reaching the sensor by about two stops. They are otherwise invaluable--everyone should have one in their bag.

Nice image... I like the warmer one better. To get even more detail in the sky you could try applying High Dynamic Range (HDR) in photoshop or similar program, if you bracketed the exposure.
