Editor's ViewPointHello there, its been raining pretty heavily here in Singapore. Bad weather we've been having lately. Sure hope the skies clear up a little so I can go out for some fresh air. My baby girl Chloe (just born over a month ago) is looking cuter by the day. I've been so busy snapping photos of here I've hardly had the time to organize them properly. Gosh, I really got to get down to doing it soon. If you're just starting out in digital photography, Canon's 5 megapixel Canon PowerShot A610 may well be worth looking at. The new DIGIC II processor makes it super fast. The 4x optical zoom lenses is great and the photos I take with auto-exposure and autofocus turn out beautiful, crisp, and with great color balance. Trust me, this camera is going to sell like hotcakes.
The MailBagDifferences between a circular and linear polarizer Question: Could you tell me what the difference between a circular and linear polarizer? Rob, NYC Answer: The basic difference is that a linear polarizer is for manually focused cameras and a circular polarizer is for cameras with autofocus. Circular polarizers are also more expensive. Whether you use a linear or a circular polarizer, the effect is the same. Light generally oscillates in all directions, but a polarizing fi lter only allows light oscillating in one direction to pass through. You can see this effect in polarizing sunglasses. In this case, the polarizer removes the light reflected off the surface of the water while allowing light from under the water to come through. Another noticeable effect is to darken and remove glare from the sky, making the color a much deeper blue. The effect can be adjusted by rotating the filter. All being said, I generally prefer not to use a polarizer because I find the effect can be unnatural, making things look more contrasty and saturated than they appear in reality.
