Athabasca HD NDX Filter can take the place of a range of graded ND filters which saves money by only needing to buy one filter and saves time on location or on set by not needing to change filters constantly to change the effect, just turn the right to get the effect you want.Athabasca HD NDX Filter puts you in control.
An example: The if your normal exposure without the filter is 1/250 of a second at f/11 the and you mount the filter and set it to the “Min” setting, then your exposure will be 1/90 of a second at the same f/11 or it could be 1/250 of a second a f/6.5 depending on which setting you want to control. If your desired effect is motion blur in the picture then turn the filter ring and watch your shutter speed drop in camera. At Max setting a shutter speed of 2 full seconds (9 stops) is possible at the same f/11 aperture.
This is an especially useful tool when creating motion blur in moving water such as waterfalls, rivers and crashing waves. Other examples of good times to use very slow shutter speeds to create blur are; moving vehicles, trains, cars and congested city traffic; blurred panning effects where the subject, a runner, bicyclist or car is clear but the background around it is blurred from the camera following its movement
Variable Neutral Density filters, and ND filters in general have these main uses:
- Slow down shutter speed for motion blurring effects like waterfalls, cars or blurred panning movement to make the subject stand out from the background.
- Allow wider apertures to be used to decrease depth-of-field, literally focusing more attention on the subject.
- Allow higher ISO films to be used in brighter lighting conditions
- Allow cine/video cameras, which have a fixed shutter-speed range, to film on brighter lighting conditions such as the beach or in snow on a sunny day.
For best results we recommends using a tripod when photographing with slow shutter speeds.
Made out of environmentally oxidized aviation aluminium. Specially design for DSLR and digital cameras with thin filter frames (6.1mm) to help avoid vignetting on super wide angle lenses are also designed to hold a lens cap.
High quality optical glass
Athabasca HD NDX filter uses the highest quality Japan made optical glass, which creates a smooth, clear image.
HD Processing is mainly used to eliminate polarized light. Using Japan imported optical glass and top quality Japan polarizing films and with secondary advanced operation, Athabasca HD NDX is certain to achieve super HD effect.
Waterproof and Stainproof Coating
Multi-coat filters are easily stained by water and dust. To prevent this, a layer of waterproof and stainproof coating is added upon the transmittance coating.
