Hoya's new polarizer lets more light through

April 15, 2010

THK today announced a new Hoya brand HRT Circular Polarizer filter that uses a new High-Rate Transparency film that transmits 25% more light and has UV absorbing properties. Read press Release

High quality filters are multi-coated, with multiple-layer optical coatings to reduce reflections. Uncoated filters can reflect up to 9% of the light, while multi-coated filters can allow for up to 99.7% of the light to pass through; the loss of light is not important, but part of the light is reflected inside the camera, producing flare and reducing the contrast of the image. Manufacturers brand their high-end multi-coated filters with different labels Hoya. is HMC - Hoya Multi Coating

Hoya Standard Filters
	Protection Filters - Ultraviolet Filters Your camera won't allow you to develop clear, crisp photos if your camera lens is damaged or dirty. You can protect your thousand dollar lens with a $20 filter if you use a UV or haze filter. These thin glass filters are designed to screw onto the end of your camera lens and you can just leave them on to protect your lens. UV filters can help protect your lenses from dust, moisture and scratches. If your lens is damaged it could cost you quite a bit to repair or replace it. The filters can also give you added benefits of correction for Ultraviolet light which can show on your film as a bluish cast and can sometimes distort distant details. UV filters let you correct for the UV effect to varying degrees. They are also useful if you are shooting mountain and marine scenes, as the haze could affect the color and clarity of the photos. UV filters can be bought for about $20. Haze Filters Haze Filters do just what they sound like, they filter out haze which is created by minute particles of vapor and dust. Haze settles in the atmosphere and can affect distant photographic scenes. Haze forms when sunlight is scattered by minute particles of matter that exist in the air. Atmospheric conditions have an effect on the amount of haze in the air. Mist, fog, smog, smoke and clouds are all different than haze. Green and red light are scattered by haze, but not as much as ultraviolet radiation, violet and blue light. If you use filters to absorb scattered sunlight you can penetrate the haze. Any filter that can absorb scattered sunlight can be considered a haze filter.
	Hoya UV Skylight (1B) Hoya Ultraviolet UV(0) Haze Filter is a wise initial investment. It helps protect your valuable investment from dust, moisture and scratches, which can lead to costly repairs. The result is an average light transmission of over 97% giving sharp contrast and well balanced color.

	Hoya Ultra Thin HMC, Neutral (Clear) Mounted in an ULTRA slim 3mm ring, this is the ultimate in clear filters. Made from completely transparent superior grade optical glass, it will not affect the color balance or performance of your lenses in the slightest. However, constant use will protect your valued lenses from expensive front element damage which could be caused by dirt, knocks and scratches.
	Polarizing Filters These filters are used to reduce or eliminate reflections. They are ideal for photographing through glass or water as the glare from water tends to be white. Polarizing filters can also reduce the effects of haze and darken the blue sky image in black and white and color photography. There are various polarizing filters available to increase color saturation in a photo without altering the hues of image colors, but there are only two principal styles. One style fits over your camera lens, while the other is made to be used over the source of light. They don't affect color, that's why polarizing filters and screens are used in both black and white and color photography. There are two pieces to a polarizer. The front part rotates so you can change the angle of polarization. If you look at the blue sky through a polarizer and rotate it, the sky appears to get darker and then lighter. These filters range in price from about $15 to $800. They come in various sizes.
	Hoya Ultra Thin UV, Circular Polarizer. Hoya's High Transmission Super-Multi-Coating minimizes reflection at the filter surfaces which reduces flare and ghosting. Hoya SMC Slim Polarizers are for wide-angle lenses, are 5mm thick, and do not have a front thread. Note! Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems without problems) • 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 • Removes unwanted reflections from non-metallic surfaces such as water or glass • 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.

	Hoya HRT Polarizer (Rotating). The Hoya HRT Circular Polarizing Filter is unique in its design since it incorporates a High Rate Transmission film that permits more visible light to be passed through the filter while still producing the same degree of polarized light. This filter now permits the equivalent of 1/3 stop more light to be taken in yet it still filters the same amount of polarized light. This can be a huge benefit to users of both digital and HD technology cameras and lenses.
	Hoya Moose Warm Circular Polarizer Glass Filter. This unique filter is the result of a collaboration between Hoya and respected wildlife photographer, B. Moose Peterson. It combines the advantages of a polarizer with the warming effect of an 81A filter. Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems without problems).
	Hoya Blue PL Color Polarizer. The Hoya Blue PL-Color filter combines a standard and a blue-colored polarizing filter. By rotating the filter, varying degrees of blue can be achieved. The effect can be seen through the viewfinder. The filter varies according to how the filter is rotated and its orientation to the sun. Filter factor is between 2.3 and 2.8 (approx. +1.3 stops). Linear polarizers are used with most manual focus cameras and are not recommended for auto focus cameras. PLEASE NOTE: All auto focus and certain manual focus cameras require circular polarizers. Consult your instruction manual.
	Hoya Vario Color Polarizer Available in five types: Y/B, Y/G, Y/R, R/B, and R/G. This filter is a combination of one gray polarizing filter and two colored polarizing filters. The color can be varied by rotating the filter frames. Many color possibilities help create new emotional effects never seen before.
	Hoya Circular Polarizer. Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting. NOTE: Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras without problems). • 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
	Hoya Linear Polarizer. Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens. PL (Linear Polarising) and PL-CIR (Circular Polarising) filters have the same effect, but it is important that you choose the correct version for your camera. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer, with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. HOYA's polarising filters do not affect the overall color balance of a shot.
	HRT Circular Polarizing Filter High Rate Transparency -25% More Light Passed Permits 1/3 More Light.
	Hoya Pro 1 Super HMC UV, Circular Polarizer. The Hoya Pro 1 Digital Circular Polarizer takes advantage of Hoya's patented optical glass technology to create a hardened glass that is thinner than the normal optical glass. This allows the overall thickness of the filter to be reduced to avoid vignetting when used with ultra-wide angle lenses.
	Hoya HMC Circularizer Polarizer. Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting. NOTE: Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras without problems). • 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.
	Neutral Density Filters These filters are designed to reduce the amount of light coming through your camera lens without changing the color. Neutral density filters can reduce the assorted colors of light in the spectrum. White and colored light is transmitted through these filters and only the intensity of the light is affected. These filters are used with black and white and color film. If you have set your camera to its fastest shutter speed along with the smallest f/stop, but still can't take the photo without overexposing the film, you can use one of these filters to reduce the exposure further. The filters help to eliminate bright, washed out sections of a photo. Neutral density filters usually range in price from about $10 to $350. They are available in various sizes.
	Hoya Neutral Density 2x Filter .- This filter combines two curved optics, one of which is neutral density and the other is clear. This gives the effect of a gradual fade towards the edges, with a difference of 1 stop from centre to edge. Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting.

	Graduated Color Neutral Density Filters - Often, you want to balance light intensity between two areas within a scene This is important outdoors to allow more sky detail while properly exposing the foreground. Exposing for the foreground will produce a washed-out, over-exposed sky, exposing for the sky will leave the foreground dark and underexposed. Graduated Color Neutral Density filters are part clear, part neutral density with a smoothly graded transition between. An ND.6-to-Clear is often best for balancing sky to foreground. The neutral gray appearance drops exposure.
	Hoya Graduated Blue Filter The Hoya Graduated Color series is similar to the Half-Color series except that color density gradually decreases near the center of the filter allowing emphasis of foregrounds or backgrounds. Their color color gradually fades out so the boundary between the colored and transparent sections will not become apparent even with the lens aperture stopped down. The filters are mounted in a rotating frame and are available in seven colors.   •
	Hoya Graduated Emerald Filter Acrylic filters similar to half-color, except that color density gradually decreases near the center of the filter allowing emphasis of foregrounds or backgrounds. Mounted in a rotating frame.Their color gradually fades out so the boundary between the colored and transparent sections will not become apparent even with the lens aperture stopped down.
	Hoya Graduated Grey Filter. Quite often the correct exposure for a background in a scene is not the best one for the foreground or vice versa. The most common problem is that the bright sky is reproduced perfectly while the landscape is underexposed; in fact pitch black most of the times. These are the occasions where the color and neutral density (ND) graduated (grad) filters can make the difference between a bad image, a good image and a better one.
	Hoya Graduated Mauve Filter.
	Hoya Graduated Pink Filter.
	Hoya Graduated Tobacco Filter. Sickly brown skies don't do your landscape photos any favors. So leave this type of filter to the car advertisers and holiday companies. It's got no place in your landscape photographs.

	Color Conversion Filters These filters are used to balance the color temperatures when you are using certain films under different light sources. An example of this would be using daylight film under tungsten lighting or vice versa. Color conversion filters are designed to convert the temperature of the film to light or of the light to film. This will allow all the colors to fall in proper perspective and look natural. These filters are generally available in two series:
	Cooling Filters
	Hoya HMC 80A Filter, Color conversion filters for the use of daylight type color films with artificial light source. 80A increases the color temperature from 3200°K to 5500°K for the use with 3200°K lamps.   •
	Hoya HMC 80B Filter- 80B increases the color temperature from 3400°K to 5500°K for the use of photoflood lamps.
	Hoya HMC 80C Filter - 80C increases the color temperature from 3800°K to 5500°K for the use of clear flash bulbs.
	Hoya HMC 82A, light balancing filter Used to increase the color temperature slightly for a cooler (bluer) tone. Corrects the tendency toward reddish tones. . These series filters are also used to prevent the reddish tones in early morning or late evening light for natural skin tones. These filters can be used together, but do not mix 81 and 82 series filters since they cancel out each other.   •
	Hoya HMC 82B Filter. For example, select the 82B when using tungsten Type B color film (3200°K) with ordinary household 100W electric bulbs (2900°K).
	Hoya HMC 82C Filter.
	Hoya Warming Filters
	Hoya HMC 81A Filter - These are light balancing filters used to decrease the color temperature slightly for a warmer (redder) tone. Corrects the tendency toward bluish tones. For example, the 81A should be selected when using tungsten Type B color film (3200°K) with photoflood lamps (3400°K) These filters can be used together.
	Hoya HMC 81B Filter. "81" series are color corrective filters that 'warm' bluish tones. They are avaible in several strengths (A, B, C & EF) with 'A' being the mildest warming effect. Available in all popular sizes.
	Hoya HMC 81C Filter. "81" series are color corrective filters that 'warm' bluish tones. They are avaible in several strengths (A, B, C & EF) with 'A' being the mildest warming effect. Available in all popular sizes.
	Hoya HMC 85 Filter These are color conversion filters for the use of tungsten type color films in daylight. 85 decreases the color temperature from 5500°K to 3400°K for the use of Type A color films.
	Hoya HMC 85B Filter. 85B decreases the color temperature from 5500°K to 3200°K for the use of Type B color films.
	Hoya HMC 85C Filter. 85C decreases the color temperature from 5500°K to 3800°K. The effect obtained is the same as with daylight type color films used in daylight.
	Soft Focus Filters - Diffusion filters are used to create soften images. A diffusion filter diffuses strong light without affecting the sharpness and contrast of the image. Thus, it is different from the effect of out of focus. Diffusion filters are mainly used in portrait work. In general, small skin defects can be eliminated almost completely, and facial contrast and wrinkles are soften. To create a better result, the aperture should be opened up so that the subject can stand out well against the background
	Hoya Center Spot Filter. When using the Hoya Center Spot filter, only a circular section of the subject in the center of the image is reproduced sharply. • All other surrounding details fade out in a blurred effect • This is a creative, artistic tool which intentionally guides the eye of the observer to the center of interest • The degree of the blurred effect varies with lens focal length and aperture opening.

	Hoya Misty Spot Filter. Available in four types: Gradual, Breeze, Windmill and Halo. They heve a sharp central image with a pleasant blurring of the outer field. With Gradual, blurring that appears to emanate from the center. Breeze has an unidirectional streaky blurring of background. With Windmill, blurring that appears to swirl about the center, and with Holo, blur that appears to radiate from a single point at the edge of the field.
	Hoya Fog Color Set The Hoya Fog Set consists of two fog filters: Fog A & Fog B. • Fog B has a stronger diffusing effect than Fog A • Both filters can be used together to produce an effect similar to dense fog • The effect can be varied by changing the aperture of the lens • Stopping down too far will reduce the effect (A&B).
	Hoya Soft, A, B Filters.
	Hoya Soft Spot Set.  This set consists of a metal screw-type filter holder and two soft-spot filters; Sand Screen and Soft Screen. Both have a clear center spot. Sand Screen has a smokey appearance while Soft Screen has an irregular surface. With Soft-Spot, the size of the clear spot in the center of the picture varies depending upon the focal length and aperture choice on the lens used. This set allows you to choose either light or heavy diffusion on the edges of the photograph.
	Hoya Diffuser Filter. The Hoya Diffuser Glass Filter produces a general softening of the image and is good for normal portraiture. The filter surface of the Diffuser is cut in a non-regular pattern thereby producing a overall softening of the photo. This filter differs from the Hoya Duto in that the Diffuser generates a overall soft image whereas the Duto produces a soft image without losing sharpness.
	Special Effects Filters There are many types of filters available that are designed to give your photographs special effects. These include filters for special color effects, star effects, spectral effects, soft effects, mist effects, multi image and multi exposure effects, graduated color, dual color and tricolor effects along with spot filters, center filters and other special effects filters. These filters are mainly made out of glass and enable you to experiment with your photos or give them specific effects. The filters are available in various colors, sizes, styles and densities. If you buy extra filters you definitely require a good camera bag with padding to hold and protect them. They generally range in price from about $20 to several hundred and many of these filters are sold individually or in sets.
	Hoya Cross Screen Filter Cross Screen adds a dramatic four-cross flare to very bright areas, giving a soft-focus effect. ldeal for photographs of ladies wearing jewellery or other objects with strong reflections.  can also be used for a variety of effects.
	Hoya STAR-SIX Filter (six-pointed light flares) Star 6, Star 8. Hoya Cross Screen filters have a surface that is etched with a fine grid pattern. Depending on the pattern, point light sources and reflections create multi-beam stars. Hoya's Star 6 Cross Screen is designed so that a 6-point star is created from point light sources and reflections.   •
	Hoya STAR-EIGHT Filter (eight-pointed light flares). Hoya's Star 8 Cross Screen is designed so that a 8-point star is created from point light sources and reflections. Check availability, sizes & current prices at

	Hoya HMC Fluoroscent FL-D Filter
	Hoya HMC Fluoroscent FLW Filter. Hoya HMC FL-W Fluorescent filter is used to balance daylight film under warm white or white type fluorescent lamps.
	Hoya ntensifiier - Blue, Green Field, Enhancement Red, Also known as a 'didymium' filter, this is used to enhance red, orange and brown subjects to give more color saturation and contrast, whilst having very little effect on other colors. It can be used in many situations such as architecture where certain building features need emphasising, or for landscapes to enhance foliage and rocky features.
	Black & White Photography Filters Filters are often used in black and white photography as black and white are actually produced as tones of gray. Filters are used to make the gray tones look like the original scene. The sky and clouds often blend together in black and white photos as white, so filters are used to separate the two. A red filter can darken blue objects more than white objects. So if you use this filter the sky will look black in the photo and the clouds will still be white.
	Black & White Film Contrast Filters
	Hoya Red #25A (HMC) Multi-Coated Glass Filter for Black & White Film .
	Hoya Yellow #K2 (HMC) Multi-Coated Glass Filter for Black & White Film A Hoya Yellow K2 is commonly used for a noticeable increase in contrast with black and white films.

	Infrared Filters Infrared filters are made to block mid infrared wavelengths while allowing visible light to pass through. They are sometimes referred to as heat absorbing filters and are ideal at cutting through haze. These types of filters are commonly used to prevent unnecessary heating in items which have bright incandescent light bulbs. Examples of such devices are slide projectors and overhead projectors. You can also get near infrared filters. These types of filters commonly are used in video cameras to compensate for the high sensitivity of the camera's sensors to near-infrared light. Infrared filters can range in price from about $20 to $450. They come in various sizes, styles and brands.
	Hoya Infrared RM90. Used for photography with infrared films. lnfrared film is also sensitive to ultraviolet rays and the shorter wavelengths of the visible spectrum so it is necessary to filter out all but the infrared rays. R72 passes only infrared rays above 720nm; RM90 passes only that above 900nm. Often used in crime detection, medical photography, detection of distribution of vegetation, etc. In ordinary photography with infrared film or infrared color film, the Y(K2), O(G), R(25A) and other filters can also be used to change the contrast or color effect. •
	Hoya Infrared IR-72. Hoya RM72 Infrared filter is used for photography with infrared films. • Infrared film is also sensitive to ultraviolet rays and the shorter wavelengths of the visible spectrum so it is necessary to filter out all but the infrared rays • Hoya makes two types of infrared filters: R72 passes only infrared rays above 720nm; RM90 passes only that above 900nm

	Hoya Intro Filter Kit Includes Um, CP, 81 a & Pouch. The Hoya 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.
	Hoya Close Up Set. Have you ever wished that your lens could focus closer than it does? Imagine that you could put a magnifying glass in front of your camera's lens. Hoya Close-up Lenses work in this fashion and are the simplest and least expensive method of close-up photography. They are available in different "powers" (diopters). • These lenses can be used individually or in any combination to achieve ultra-close focus • The maximum magnification achieved with these attachments will depend on the focal length of your lens as well as the actual close focusing capability of that particular lens • A +1 close-up lens will allow you to focus your lens somewhat closer than it already does; A +2 close-up lens will allow you to focus closer than the +1; A +4 lens will allow you to focus even closer than a +2 • A +1 combined with a +2 will equal a +3, while a +2 combined with a +4 will equal a +6, and so on

Press Release

THK Photo Product, Inc announces the new HOYA HRT circular polarizer filter. This filter uses a newly developed High-Rate Transparency film that passes more visible light through the filter while still filtering the same amount of polarized light. The HOYA HRT circular polarizer filter transmits as much as 25% more light through the polarizing film giving the photographer about 1/3 stop more light than a standard circular polarizer. This new polarizing film is also used in the latest HD LCD TVs.

The glass of the HOYA HRT filter also has UV absorbing properties, making the HRT aq combination UV/circular polarizing filter.

The most common use for a circular polarizer filter is to darken bright blue skies in outdoor photography, but they can also reduce or eliminate reflections from non-metallic surfaces such as glass and water. By rotating the outer ring of the filter the change of effect can be seen by looking through the filter or through the viewfinder if it is mounted on a camera.

HOYA is the world's largest optical glass manufacture, making glass to spec for almost every camera and lens manufacturer. HOYA is also the world's largest filter manufacture.
