Easy to operate / easy framing / easy focus with a tripod mounted camera, use the brightest setting for framing and focus and then increase the density to your desired level by simply turning the outer filter ring. 1. Framing and focus 2. Turn the outer ring 3. Adjust the aperture and shutter speed ...

Polarizing effect cancellation the variable ndx filter changes the brightness of light using a polarized filter. This new filter uses a “polarizing effect cancellation” where a polarized filter is used, but purely for controlling the amount of light with no effect on color balance, glare or reflecti...
Page 7: Avoid Vignetting
Avoid vignetting the singular versatility of the variable ndx filter not only replaces a whole set of stacking neutral density filters it also removes vignetting which may be caused by using multiple filters. 7 stacking nd filters with variable ndx filter ndx-manual-f02 11.8.3 7:45 pm page 7.

The benefits of having a depolarization plate variable ndx filter using a depolarizing plate random polarization is eliminated when natural light passes through the depolarization plate, minimizing any change in color by using 2 layers of polarizing film. 8 other fader nd filter - color change occur...
Page 9: Exposure Values Chart
9 exposure values chart the variable ndx filter changes exposure values by rotating the front element of the filter. In order to evaluate the correct exposure to use, please refer to your camera’s built in meter. (please note: the scale position on the side of the filter is not proportional to the n...
Page 10: For Longer Exposures
For longer exposures without changing the aperture, the variable ndx filter allows the freedom to change the shutter speed according to the effect desired. For example, without adjusting the aperture, the same 1/60 scene can be taken using the variable ndx filter with shutter speeds from 1/20 to 6 s...

Page 12: For Wider Apertures
12 for wider apertures with the variable ndx filter, the shutter speed remains constant for a wide aperture easily creating a blurred background effect. With variable ndx f1.4 1/4000sec.

16 for hdslr movies for hd video-enabled cameras, use the variable ndx filter to easily adjust light control and shutter speed. The variable ndx filter makes it simple to produce blurred background effects, simulate a night scene or create manual fade in / fade out effects. It is also perfect for us...

18 safety precautions human injury or material damage may occur if filter is used mistakenly because instructions are not observed. Do not drop or impact filters. If glass breaks, do not touch it with bare hands, as doing so may cause injury. Moreover, filter frame may become misshapen, and unattach...

19 structural weakness - color shift when using a neutral density higher than 450, cross-like color variations may occur. Structurally this problem cannot be eliminated due to the 2 layers of polarizing film. Upkeep to clean off dirt from glass, add a small amount of lens cleaner to a lens cloth or ...
