USING A POLARIZING FILTER

Circular Polarizing Filter

A circular polarizing filter screws on the front end of your lens and works something like sunglasses for your camera. A polarizer can help reduce glare and remove unwanted reflections from non-metallic surfaces such as water or glass and improve color saturation of skies, lakes and streams, and wet surfaces.

You can see the effect of the polarizing filter through the viewfinder and change it by rotating the filter.

A polarizer works best and has the greatest effect when you are oriented 90 degrees from the sun. The least effect is seen when shooting toward or directly away from the sun.

You do lose some light to the filter. The filter factor depends on how the filter is rotated and its orientation to the sun. Generally you lose approximately 1.3 stops. This means slower shutter speeds!

Here is how you use it. Screw the filter onto your lens, look through the viewfinder and turn the filter ring. When you see the sky go a deep rich blue you have reached the full effect.
