I just bought myself a HOYA Digital 52mm Pitch=0.75 Circular Polarizer.
A circular polzarizer can greatly increase contrast and color saturation, eliminating reflections from glass and other non-metallic surfaces, and darkening blue sky.

Eliminating Reflections
For maximum polarization, the incoming light source must have an incident angle of 30 degrees, and the camera must be aimed at the subject at an angle of 30 degrees from the other side.
Figure 1. Explaining the principle of Eliminating Reflections.
Polarizers can also eliminate reflection from water, making water more transparent. This is particulary good for taking pictures of aquatic life in a pond.Polarizers are also applicable in eliminating reflections when shooting highly reflective surfaces such as the body of a car or metallic objects or even the screen of a CRT/LCD.
Here are some results from a setup trial to test the functionality of the PL-Cir.
The Trial Click on thumbnails below to enlarge full-sized images.
The left most image shows strong reflection of the window grille on a piece of tempered darkened glass. Under the glass, there are some good looking brochures and cards that I've collected. They start to become visible when the nasty reflection has been removed as shown in the right image.
The left most image shows the scene without the polarizer. The middle image shows the scene with polarizer on. The right image shows the maximum effect with this polarizer. At maximum effect, 'VEL' of the 'MARVEL' word is still slightly visible which the face of Mary Jane is no longer visible. All images are captured on manual mode and the same settings.
The left most image shows the scene without the polarizer. The middle image shows the scene with polarizer on. The right image shows the maximum effect with this polarizer. At maximum effect, the face of Mary Jane is not visible while the white gown on Mary Jane's chest is still slightly visible. It is also obvious that the polarizer cut the light intensity as well (working like a sunglass), by comparing the image without (left) and with (middle & right) the polarizer. All images are captured on manual mode and the same settings.
Darkening the Blue Sky
Another use of polarizers is to darken the blue sky. The principle of application is as shown in Figure 2. Point your index finger at the sun, extend your thumb at a right angle to your index finger (like the shape of a pistol) and pointing the lens in the direction of the thumb to get the maximum effect.

After determining the position of the maximum effect, aim your camera and rotate the top ring of your polarizer. You should be able to see the color change on the LCD monitor (for PNS), however, for DSLR is much more tricky asyou might need to trial-and-error. Then, compose your image and rotate the top ring until the desired effect is reached. Finally release the shutter to take a photograph.
Increasing Contrast
Polarizers can also increase the contrast of a photograph because reflection from the subject is removed, and thus the subject have better definition.
Notes
It is not advisable to stack polarizers on top of any other filters because it will result in vignetting.

Having understood more about metering concepts, I am taking this chance to make use of metering concepts and messing around with shadows. Although this is easier with a PNS than DSLR and this can be done with 'Highlights/Midtone/Shadows' in Photoshop, I still prefer to keep post-processing to the minimum.

sekali wat if u jus attach a piece of shades across ur normal lens u can polarize stuff liaos?
rationale is similar.... (do not quote me on that)
anyway its a must have 'toy' for the most amateur.
you like the product shots?
Shadow works wonders!
