    uv filter
  • UV filters are individual compounds or mixtures to prevent ultraviolet (UV) light from coming through. UV filters are used in sunscreens to protect skin or in photography to reduce haziness or fogginess created by ultraviolet light.

  • This is an Ultra Violet absorbing filter that helps overcome the abundance of blue in outdoor photographs. Not really necessary in digital photography as the camera's white balance system adjusts for the colour temperature of the scene.

  • This coating is a filter for the harmful UV radiation. The coating is either put on the lens or is imbedded into the lens to protect your eyes for the harmful effect of the sun’s UV radiation.

Hoya 49mm HMC Multicoated UV (0)


Hoya 49mm HMC Multicoated UV (0)



Absorbs the ultraviolet rays which often makes outdoor photographs hazy and indistinct. A muliti-purpose fine-weather filter for color as well as black and white films. Also serves as a permanent lens protector. HMC (Hoya Multi-Coating) These popular filters are renowned for their ability to minimise reflection at the filter surfaces which reduces flare and ghosting. The result is an average light transmission of over 97%, giving sharp contrast and well balanced color. HOYA HMC filters are recommended for enhancing the performance of today's multicoated lenses.

Taken to demonstrate K20D high ISO capability
taken as RAW and PP done on the PC in an effort to maximize image quality
Lens is SMC Pentax-M 35/2.0 f=5.6

This photo was posted as part of a discussion about certain compact cameras alleged ultra-high-ISO capabilities.
Please note that this picture was taken with a rather good APS-C sensor (23.5X15.6mm compared to 5.3X4 to 7.6X5.7mm used in compacts) and an old but very sharp prime lens. Also note that most compacts does not record RAW files and in-camera processing is usually inferior to that done on the PC.

1975 asahi pentax kx single-lens reflex camera with smc pentax-m f/1.4 50mm lens, a 49mm uv filter, and a soltron 177 solid state. klik! by mahendra.

kx was the first single-lens reflex camera i ever used. i was 14 years old, i think, and spent two years after taking lots of pictures with it. since my parents was still using it too, i gave it back to them in 1992, and got myself a yashica fx-3 slr.

    filter
  • A porous device for removing impurities or solid particles from a liquid or gas passed through it

  • A screen, plate, or layer of a substance that absorbs light or other radiation or selectively absorbs some of its components

  • A device for suppressing electrical or sound waves of frequencies not required

  • 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

B+W 52mm Circular Polarizer with Multi-Resistant Coating


B+W 52mm Circular Polarizer with Multi-Resistant Coating



Highly efficient standard circular polarizing filter for all cameras with beam splitters in the light paths of their TTL exposure meter and with autofocus lenses. Circular polarization has the same pictorial effect as linear polarization, but allows for proper exposure metering and/or autofocus distance settings. B+W Polarizers increase color saturation and reduce reflections. The neutral gray color and plane parallel polarizer material guarantee optimal image results. High-quality optical glass ensures excellent pictorial quality. The filter factor varies according to how the filter is positioned in relation to the sun. Filter factor is between 2.3 and 2.8.

B+W 67mm Kaesemann Circular Polarizer with Multi-Resistant Coating






Circular polarizing filters are made for all cameras with beam splitters in the light paths of their TTL exposure meter and with autofocus lenses. Circular polarization has the same pictorial effect as linear polarization, but allows for proper exposure metering and/or autofocus distance settings. The "high-end" polarizing foils of the Kasemann-type filters are neutral in color, they have a higher efficiency than conventional polarizing foils and they are cemented between high-grade plane-parallel optical glass. The resulting sandwich is then precision-polished again to achieve highly accurate plane-parallel surfaces. Subsequently they are edge-sealed to protect the foil against humidity. Discriminating photographers regard the B+W Kasemann-Type Polarizing Filter to be the very best of all polarizing filters. They are well suited for applications that require the highest possible imaging quality, especially with high-speed telephoto lenses and apochromatic lenses.

    uv light
  • Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 nm, and energies from 3eV to 124 eV.

  • Electromagnetic radiation in the range of 300 to 400 nanometers. UV radiation is not visible and therefore “UV light” is a misnomer. UV radiation has been implicated in the degradation of photographs and papers.

  • Radiation present in sunlight, fluorescent light, and to some degree incandescent light. UV light degrades photographs, papers, plastics, adhesives, fabrics and colorants.

    pond
  • Pond was a grunge band from Portland, Oregon. They formed in 1991 and broke up in 1998. They were signed to Sub Pop (first two albums) and the Work Records sub-label of Sony Records (last album).

  • (of flowing water or other liquids) Form such a lake

  • A pond is a body of standing water, either natural or man-made, that is usually smaller than a lake.

  • Hold back or dam up (flowing water or another liquid) to form a small lake

  • a small lake; "the pond was too small for sailing"

Purely Products PUVH2307 7-Watt UV-C Germicidal Ultraviolet Replacement Bulb



Purely UV-C Replacement Bulbs G23 BasePurely UV-C Replacement bulbs offer a much higher concentration of ultraviolet light than even the sun, making them highly effective as a cleaning and purifying agent for pond and aquarium pumps and clarifiers.What is UV and How Does it Work?UV light is germicidal - i.e., it deactivates the DNA of bacteria, viruses and other pathogens and thus destroys their ability to multiply and cause disease. Specifically, UV light causes damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevent the DNA from being unzipped for replication, and the organism is unable to reproduce. In fact, when the organism tries to replicate, it dies.What are the Beneficial uses of UV Light?Ultraviolet technology is a non-chemical approach to disinfection. In this method of disinfection, nothing is added which makes this process simple, inexpensive and requires very low maintenance.How do Ultraviolet Water Purifiers Work?UV water purification units contain one or more germicidal ultraviolet lamps. The germicidal lamp is a short wave low pressure mercury vapor tube that produces ultraviolet wavelengths that are lethal to micro-organisms. This wavelength is in the region of maximum germicidal effectiveness and is highly lethal to virus, bacteria and mold spores. Therefore, the water or air that passes through the chamber is exposed to the germicidal UV light and the genetic material of the micro-organism is deactivated, which prevents them from reproducing and renders them harmless.Reference Tool for choosing the correct UV-C Replacement Bulb:Match your existing bulb to one of the bases.Match the wattage or length of your bulb. Some bulbs have a different length for the same wattage -- so be sure to match both watts and length.H-Series:The Purely UV L-Series carries the industry standard 2G11, G23 and GX23 base.The "H" is for the H-look with parallel glass connected by

La défense - The Takis pond





La Defense is a major business district for the city of Paris.

Here the Takis pond built in 1988 by the greek artist Takis and his 49 light stems. This pond is built just upper the subway station, Esplanade de la Defense, Line 1. On the right side, RTE-Nexity tower, is the initial tower to be build on La Defense area in 1966. The tower was refresh in 1988 and kept is original name, Initial Tower.
In the center, you can see the Arc de Triomphe, the Paris gate initiated by Napoleon in honor of his victorious army. unfortunately, his success story finished before the end of the build !!!

A mystery: There really is no way for a fish to be able to get up into the top plant pond. Even an egg would have to travel through the skimmer filter, through the UV light, and up through three layers of filter padding in the waterfall. But there are several baby fish up in that pond, blissfully swimming around the plants. How'd they get up there?
