    circular polarizing
  • (Circular polarizer) A polarizer is a device that converts a beam of electromagnetic waves (light) of undefined or mixed polarization into a beam with well-defined polarization. The common types of polarizers are linear polarizers and circular polarizers.
  • A screen, plate, or layer of a substance that absorbs light or other radiation or selectively absorbs some of its components
  • device that removes something from whatever passes through it
  • remove by passing through a filter; "filter out the impurities"
  • an electrical device that alters the frequency spectrum of signals passing through it
  • A porous device for removing impurities or solid particles from a liquid or gas passed through it
  • A device for suppressing electrical or sound waves of frequencies not required
  • A climbing or sprawling evergreen shrub with ornamental foliage and waxy flowers, native to Southeast Asia and the Pacific and grown as a greenhouse or indoor plant
  • any plant of the genus Hoya having fleshy leaves and usually nectariferous flowers
  • Asclepias L. (1753), the milkweeds, is a genus of herbaceous perennial, dicotyledonous plants that contains over 140 known species. It previously belonged to the family Asclepiadaceae, but this is now classified as the subfamily Asclepiadoideae of the dogbane family Apocynaceae.
  • Hoya is a genus of 200-300 species of tropical climbing plants in the family Apocynaceae (Dogbane), native to southern Asia (India east to southern China and southward), Australia, and Polynesia. Common names for this genus are waxplant, waxvine, waxflower or simply hoya.

Moose Warm Polarizer filters, an exclusive collaboration between Hoya and respected wildlife photographer and conservationist B. Moose Peterson of Wildlife Research Photography, are a combination of a polarizer and an 81A warming filter. For many years, polarizers have been used to remove reflections from non-metallic surfaces such as water and glass as well as being used to darken blue skies to increase contrast in scenic photography. When using a camera with a split beam metering system (a metering system that employs a polarized half mirror) which is most of today's auto focus camera bodies, traditional linear polarizers will cause exposure errors due to their light absorption properties. Circular polarizers yield the same optical effect while not causing exposure problems with modern metering systems A side effect of both linear and circular polarizes is they "cool down" or make the over-all color balance of a scene slightly bluish. The addition of the 81A glass corrects the color temperature, bringing the scene back to the original 5500K for daylight film's color balance. The 81A glass creates a much more pleasing and warm color balance to the entire scene while the circular polarizer increases color contrast and reduces the effect of atmospheric haze.

Using a Hoya 72mm circular polarising filter on this one. It just cuts all the glare off the water and makes the colours burst.

Bought a new Circular Polarising Filter. this is a pic of our pool, I love how the reflection in the pool is so clear.

Hoya 72mm Introductory Filter Kit, UV, Circular Polarizer, 81A and Filter Wallet
The Hoya 72mm Introductory Filter Kit is a general purpose starter kit. Ultraviolet (UV) Filter Hoya Haze (UV) Filters are wise investments. They help protect your valuable investment from dust, moisture and scratches, which can lead to costly repairs. Circular Polarizing Filter Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun. Warming Filter (Intensifier) The Hoya Warming filter controls the bluish coloration that affects daylight film. They can also remove excessive blue from the effects of electronic flash. Reduces blue to green color and makes the color of human skin look more sun-tanned. Combination with Pro 1UV filter is recommended for outdoor shooting. Note! Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras). UV Filters ? If desired they can be left on the lens at all times for protection ? Haze filters provide additional benefits of correction for Ultraviolet(UV) light which can register on film and videotape as a bluish cast and can obscure distant details ? Ultraviolet filters allow you to correct for the UV effect to varying degrees Circular Polarizing Filters ? This filter eliminates ultraviolet rays to remove haze from outdoor shots as well as polarizing the light to remove reflections, and increase color saturation, without affecting the overall color balance Warming Intensifier ? Works on the blue/green end of spectrum to give subjects a "warmer", healthier, more tanned look.
