ND Filters, also known as Neutral Density Filters, are often used in imaging or laser
applications where excessive light can be damaging to camera sensors or other optical
components. ND Filters are also ideal for preventing excessive light from causing
inaccurate results in photometer applications. ND Filters are designed to reduce
transmission evenly across a portion of the spectrum by absorbing or reflecting the portion
of the light that is not being transmitted.
- ND2,ND4,ND8,ND16,ND32,ND200,ND400,unlimited adjusting between all levels,providing you with more freedom of creation;
- Blurring water motion (e.g. waterfalls, rivers, oceans);
- Reducing depth of field in very bright light (e.g. daylight).you can in the strong sunlight using a slow shutter;
- When using a flash on a camera with a focal-plane shutter, exposure time is limited to the maximum speed—often 1/250th of a second, at best—at which the entire film or sensor is exposed to light at one instant. Without an ND filter this can result in the need to use f8 or higher;
- Using a wider aperture to stay below the diffraction limit,easier to achieve your desired depth of field effect;
- ND filter using well-developed coating,color is high,no color deviation;
- Reduce the visibility of moving objects;
- Add motion blur to subjects;
- Extended time exposures;
- High quality worthy of trust!
