I am Polarized

A lot of people are described as being "polarizing". Those who like them, really like 'em; those who don't, really don't.
But, I'm gonna discuss a different type of "polarizing".
It's a filter.
Goes on the front of your camera lens.
For you non-shutterbugs, it's those sunglasses that take the glare off the water, or off your car's windshield. 
Polarizing filters act the same way. They can subdue glare, and often make for a much "richer" image. Passing by a demolition site earlier today, a lone satellite dish on top of a pole caught my eye. The sky (not skies...there's really only one, in spite of what TV weather guys say almost every night) was a rich, royal blue. Low humidity contributes to this. Too bad there were no white, billowy clouds, to make it even more pronounced.

Picture number one. The scene without a polarizer:

Looks nice, and all that. With a little enhancement, courtesy of PhotoShop, I could spruce it up a touch. But, as a photographer that started with film (and I still love it), you gotta shoot it right, under most conditions, to get the perfect image. Especially when dealing with transparency films. Not a lot of enhancement opportunities, and film is not very forgiving.

Now, picture number 2. With a circular polarizing filter.

Much richer.
On the water, at the beach, or on snow scenes (once the sun comes out), you'll be impressed at what a polarizer can do for you. Don't buy those $4 ones, though. Remember, you're putting something between your subject and an expensive lens. You don't want to degrade your image. Good quality polarizers, depending on their sizes, can cost $40-$100.
Pick up one. And, good shooting.
