Product description

Relatively strong filter, which despite its density offers a pleasant and natural effect to any photography and adds gentle brown tone, medieval or dramatic/dark antique look and atmosphere. The filter is significantly different from others such as the tobacco filters which not only darker the image but it also added quite a strong color (brown-tobacco) cast and saturate the colors...

PROPERTIES OF THE
CR-39 MATERIAL:


CLASS A OPTICAL MATERIAL



The material used for the production of 84.5mm filters is commonly used worldwide for the production of corrective eyeglasses, which shows the extraordinary optical properties.  While conventional optical glass was  used in eyeglasses in the past, the trend of the 21st century is called organic glass, which offers almost identical optical properties, as well as significantly is lighter in weight, more flexible, and more resistant. Although these are some characteristics found in the production of eyeglasses, most photographic filters which are currently on the market use this material as well.

MILITARY MATERIAL




Materials which are used in various areas of the military and aviation are usually known as the toughest, highest quality and often unavailable to the general public. Organic glass is used in the manufacture our filters and are also commonly used in military aircraft to cover the cockpit.  This material is highly scratch resistant when washed, resistant to very high pressure, very elastic, light weight, and has excellent optical characteristic, anti-reflective ability and more! Typically, the durability of these materials is appreciated in situations such as combat pilots operating in difficult conditions and professional photographers shooting during harsh weather
conditions and or/time stress where filter can be scratched or damaged if it was made from basic plastic material, not organic glass.


REFRACTIVE INDEX AND ABBE NUMBER

 

The material used in these filters (84.5mm) achieves the best features in a variety of other optical parameters such as Abbe number with a value of 58, guaranteed minimum (hardly any) negative impact on the chromatic aberration  (which is often a negative phenomenon cheap lenses) and more. If we combine the optical properties with mechanical properties of flexible polymer / monomer we get almost perfect material, and that is what we
have, right? 


HIGHLY SCRATCH RESISTANT MATERIAL

While ordinary plexiglass or resin materials can be relatively easy to scratch, our organic glass is completely a different case. Our filter material is characterized by extremely high scratch resistance and common materials such as fingernails and sharp objects (plastic holder) make it almost impossible to scratch. This is another reason why it is used not only in correction glasses but also the military.  More information about this type of scratch resistance of organic glass can be found in the FAQ section.


HIGHLY ELASTIC MATERIAL



Most ordinary glass breaks easily when it falls on the ground/floor, but organic glass is very flexible. Due to the glass being flexible, if dropped on the ground/floor or you or handle insensitively, it most likely will not break or shatter.

 

MADE IN EUROPEAN UNION


All of our products are completely hand-made in the European Union.  Using the most advanced manufacturing processes, strict compliance adherence with European directives and legislation. Our trained team of technically skilled manufacturing specialists provide a guaranteed premium quality product. Some might question why certain products such as Swiss crafted watches are manufactured only in Switzerland and not outsourced in Asian country for better prices. Our response is that highest quality products with high value, where every smallest detail matters can be made only completely in-house, under the strict supervision of pedant specialists
working several years in hi-tech optics industry.  Simply high quality of our products and reputation of our brand is much more important than reduction of production costs by outsourcing in developing countries (Vietnam, Thailand, China) by less skilled staff.

We take pride in our work, in our products and we are proud to say they are all hand-made manufactured in the European Union. 


FILTERS DIMENSIONS:


 

Professional line are square shaped filters fully compatible with holders of „P“ type square filters (width 84-85mm)

 

Advantage of Professional line filters comparing to classic filters is mainly in their dimensions thus their big (unlimited) flexibility in real use. While you can move standard filters (size 84x100mm) only few centimeter up/down regarding horizon of photographed scene (which could be often very limiting you in your work), filters from Professional line offer you unlimited flexibility – you can move filter up/down virtually without limitations – 6 and more centimeters up/down because of its size (84x150mm). Would you like to set transition/graduation of filter only few centimeters above bottom of photography or would you like to darken only few first centimeters of upper part of photography/clouds? Really no problem with Professional line filters.

Next advantage of Professional line is fact that you can use every filter as graduated but also as full/solid (one color filter) at the same time – because transition/graduation of filter is situated in half of filter (about 7,5cm)

 

84,5mm company presents series of Professional line filters in following tones/types: Neutral Density filters with soft graduation: light, medium, strong and Neutral Density Hard – with hard transition: medium, strong, as well as Reversed ND with reversed graduation for shooting of horizons/landscapes during sunset in densities: medium and strong.

 

Through selected dealers/stockists you can buy also colored filters from Professional line (editions upon special order/request)

Neutral Density filters are designed to increase dynamic range of your photography and it is not possible to simulate them in computer. Because digital cameras have significantly limited dynamic range (e.g. much lower than human eye) almost every time it happens that during outdoor shooting upper part of photography/sky is over-highlighted while bottom part is really dark. Neutral Density filters fully eliminate this problem of digital cameras and offering grandiose, full photos with big depth, atmosphere and realistic third dimensionality.

 

Usual problem of neutral graduated filters being their color cast which appears on clouds (usually purple color). This is very negatively perceived by photographers. Thanks to more than 3 years of research and using highest quality available materials as: original organic glass CR-39 from patented producer from U.S.A. instead of Chinese equivalents and British optical pigments this negative fact (known from other brands) have been successfully eliminated (no purple cast have been noticed) as evidenced by many reviews and awards worldwide.

 

Every Filter is individually inspected visually as well as mechanically/optically/digitally in our testing lab, while every one filter is certified by signature of chief of main output control.
