Adeal has announced local availability of the the Hoya Variable Density filter, which uses two polarizing layers to control the amount of light that passes through the filter and into the camera lens.
It’s perfect for creating artistic blurring shots of motion on water, cars, people ‘or almost anything that moves,’ and substitutes for a collection of ND filters of varying strength.
At its minimum effect, the filter passes 1/3 of the light in a scene – equal to 1.5 stops on the aperture or shutter speed.
At its maximum effect, the filter passes just 1/400 of the light in a scene – equal to 9 stops on the aperture or shutter speed.
After the filter is mounted on the lens, turning the filter ring between ‘Min’ and ‘Max’ can greatly control the amount of light entering the lens. With the Hoya Variable Density filter, it’s possible to shoot with fast lenses in full sun for a very shallow depth of field, or to slow down the shutter speed so it is open for several seconds in full sunlight.
The Hoya Variable Density filter uses high-quality optical glass from Hoya Corporation, the world’s largest optical glass manufacturer, and is available in sizes 52mm to 82mm.
This is a great accessory sale – as it almost demands that the user matches it with a tripod for taking photographs with slow shutter speeds.
