polarizer中文

A circular polarizer is designed to do one thing: remove or control reflections from surfaces like water, glass, paint, leaves, sky, buildings, streets, and the list goes on. When light hits those surfaces they create glare that increases highlights, reduces color and detail. Almost every scene contains some kind of glare, and a circular polarizing filter will help you control that glare before it ever gets to your image.

These reflective optics focus light without chromatic aberration, making them especially suitable for broadband sources.

Polarizer Filter

A polarizer frame is made of two pieces attached together. One holds the glass and the other attaches to your lens. So, once the filter is secured to the lens, the front part of the filter will rotate freely. It is this rotation that will allow you control the polarization effect. By looking through your viewfinder or at your screen begin rotating the filter until you get the amount of reflection removal you need. Depending on the lighting conditions the effect may be dramatic or subtle so really pay attention to the details and the areas that are most important to you to control. Below are examples of common subject where a circular polarizer is used.

A circular polarizer darkens blue skies and helps bring out clouds. This helps during both blue sky days as well as cloudy sunsets and sunrises.

Taking a photo of a house or car? Most paints are shinny and reflect more light than needed, which in turn lightens or washes out their color. A Circular Polarizer reduces or removes the reflections for better color.

All polarizers are not created equal and poor quality glass, low quality polarizing films, and bad frames can affect sharpness, resolution, contrast and color. Polarizing glass is made by sandwiching the "polarizing film" between 2 pieces of glass then using special adhesives and manufacturing processes to make them into a single unit. If anything gets messed up during this process then you end up with a filter that will ruin a great image. Here are features to look for:

When photographing any scene with water in it, you’re exposed to a great amount of glare. A polarizer helps reduce the glare so that you can see the true color of the water, as well as see through to some of the rocks or other details below the surface of the water.

A depolarizer is a device that obliterates the polarization of a polarized beam by reflecting the beam in all directions at right angles to its axis.

We’ve all seen lots of reflections off windows and other glass. A circular polarizer reduces or removes the reflections to see what is on the other side. Something that cannot be done later in any editing software.
