Would you like to add some punch to your images? Then try a polarizing filter. A polarizer is the one filter every photographer should have handy for landscapes and general outdoor shooting. By reducing glare and unwanted reflections, polarized shots have richer, more saturated colors, especially in the sky. Be aware that you must turn the filter ring to where the image looks its best. Also you will lose approximately one and a half stops of light coming thru your lens. The filter is a neutral grayish color and cuts down the amount of light coming into your lens. Therefore do not leave it on when you are taking inside photos.
If you own a compact point-and-shoot camera that does not accept filters, don’t fret. My husband uses this trick. If you have a pair of quality sunglasses, then simply take them off your head and use them as your polarizing filter. Place the glasses as close to the camera lens as possible, then check their position in the LCD viewfinder to make sure you don’t have the rims in the shot. The exposure meter will read the sunglasses and your photos will look more saturated in colors, especially good for bright sunny landscape photos.
A polarizing filter is also great to cut glare when taking outdoor photos during the daytime. It cuts glare, so if you are photographing a car show and want to see the color of the car instead of the reflections on the metal, try turning the ring on the filter and you will see the glare diminish. Great for shooting thru glass and water also.
You can purchase a polarizer filter at your local camera shop or at B&H Photo thru the internet. Make sure you know your lens thread size which is shown on your lens as a #mm or look for the circle with a line thru it and that is your filter thread size. Every lens you own could be different thread sizes so be aware that you may have various thread sizes for each lens.
