Fader Nd filter can change the luminous flux substantially with freedom, reducing the amount of light from two times of the lowest to about 400 times of the highest. It can easily replace dozens of all grades of density ND gray filters(maximum equal to 3 ND9) (1 ND9 light can be reduced three grade light).The operation is extremely convenienct when selecting your desired density, just rotating filters. The index marks on the filter let you know exactly the amount of reduction at a glance.

Features:

• In the Strong light environment, to shoot the scene of small depth of field (Blur the background, thus showing the main body). 
• In a bright environment, using high-density photography to shoot the scene of dynamic objects.
• When transferred to high-density, to shoot the clarity of the details which is usually difficult to observe by the human eyes (such as steel, welding, solar eclipse, magma, etc.) in the  high-temperature and bright environment. 
• On a sunny day and night shooting simulation (For example: Under the backlighting, the water has a strong reflection, you can transfer the POL Filter to an appropriate density, and then jump spot density control exposure, access to the charming moonlight atmosphere).
• In a bright environment to shoot strong dynamic screen (such as streams, waves, athletes, wind and vegetation, etc.), often use a longer shutter time, to blur the whole movement or a part.
• Modulation to the appropriate density for flash photography at close distance.
• Used in variety of the scenes which need a wide range of adjustment the amount of light.
• It also applies to a variety of wide-angle lens
