Features:
* Partly reduce light input to avoid exposure.
* Suitable for light unbalanced environment or the scene where you need slow down the shutter, like shooting waterfall, flowing water, stream of people, traffic flow, floating cloud, etc.
* It's hydrophobic, and oil proof, resist dust, easy to clean.
* Glare Protective and no light reflection.
* High quality guarantee.
Graduated ND filters kinds:
Performances:
Adapt high quality optical glass which is fine polished, and nano coated with AR film, so light light transmittance is very high, then definition is very good. To make low / no color difference, it's evenly coated by ND film which allows different wavelength of light to pass through it equivalently.
