Why a Polarizer Filter?

Natural light spreads straightforward in waveform in all directions. Pure sunlight is polarized and has a high color unit. When penetrating the atmosphere, part of it is scattered, which is superimposed as a blue-gray haze all colors. This proportion can often be dimmed with polar filters. If light also falls in the flat angle of about 35 degrees to a reflective surface, e.g. Water, glass, plastics, colors (with the exception of metallic surfaces), the light is reflected and polarized. If a properly oriented pole filter is now used, the reflexes are absorbed and the pure colors can arrive on the film or recording chip. Water surfaces are transparent, the flower through the celestial polarization is damped, the colors are far strong and sadden.

The Heliopan pole filters are supplied in a rotatable version with numeric wreath, so that the desired position and effect on each camera types can be easily set.

What is the difference from HT Polarizer to Standard Polarizer

The filter factors of polarization filters are usually between 4 and 8. That corresponds to up to three aperture levels. The Heliopan High Transmission (HT) Polfilter has a filter factor of 2 to 3, this corresponds to 1 to 1.5 aperture stages.
The Heliopan High Transmission Polifilter has a filter factor of 2 to 3 and thus only a light loss of about 1 to 1.5 aperture stages

HT Polfilter are ideally suited for the available light and freehand photography, as it can use the shorter shutter speeds of your camera due to the lower loss of light.
Another advantage is also the lighter search picture.
With this filter you can use the low ISO settings of your cameras and thus achieve the best possible quality.
