Heliopan

Heliopan

Whether in analogue or digital photography, the best results are always achieved when using filters at the time of taking the photograph and not when manipulating on computer software back in the office, as once any unwanted light or colour is recorded, then the ability to remove it affects other parts of the image. Heliopan filters are made in Germany under very strict rules and regulations, to ensure that each filter is manufactured to the highest possible standards. All the raw materials are sourced for their quality, from the brass that is used in the metal retaining rings, to the German Schott Glass, which offers un-rivalled clarity and performance. The carefully thought-out matt black rims on the filters, mean less intrusive light reflection and all the filters have at least one high quality hard coating on each filter side to reduce stray light, maintain high contrast and avoid flare. Reflections are reduced from 8% to 2.5% for each 'glass to air surface on each side of the filter and the SH-PMC filters have the added advantage of an extra top coating which is dust and moisture repellent, making the filters easier to look after.The Schott glass group, manufactures glass for a wide range of products, including medical and laser glass and glass used in applications where radiation is used, so they have outstanding expertese in the area of optical brilliance. The company continually updates its manufacturing processes, to reflect the changing technology that is constantly improving standards across the board.

Ultra Violet Filters

The ultra violet filter is designed to absorb the short waves in the light spectrum so that when it is hazy a clearer image can be obtained and the blue light cast is lessened, giving a more acurate colour rendition. The added advantage is that no exposure compensation is needed and the expensive lens that the filter is attached too, is protected from dust and finger prints.

Circular Polarising Filters

As light comming from the sun is not polarised, parts of the light become patially polarised due to the scattering of particles in the atmosphere. A polarising filter reduces reflection and glare and can add contrast to skies. It is neutral in colour, can be used for black and white or colour photography and also controls reflections. Polarising has its greatest impact at 90 degrees to the sun, hence the need for it to be circular. Once attached, it is easy to rotate the outer ring to align it in the best possible place for reflection free photography.

Neutral Density Filters

Neutral desitiy filters are particulary good for reducing light in over-bright situations. Particulary useful when taking photographs of snow scenes, or very bright situations near the sea. The depth of field is reduced when using this filter as the aperture required to take the shot is, necessarily, larger. They are great to use, if long exposures are required in bright sunlight and have been manufactured using Heliopans neutral colour schott glass and are available in three densities depending on the level of brightness encountered. They can be particularly useful on digi camcorders where there isn't a huge choice of apertures.

Infrared Filters

Excellent for taking creative photographs, the Infra red filters are made from Schott glass which only allows certain areas of the Infra Red Spectrum to pass through, the RG715 (88A) the RG780 (87), RG850 and RG1000.
