Neutral Density (ND) Filter ND4x - 67mm
|Neutral Density ND, NDx||Transparency||Exposure Factor||Additional f-Stops|
The use of an ND filter allows the photographer to utilize a larger aperture that is at or below the diffraction limit, which varies depending on the size of the sensory medium (film or digital) and for many cameras, is between f/8 and f/11, with smaller sensory medium sizes needing larger sized apertures, and larger ones able to use smaller apertures.
Examples of this use include:
- Blurring water motion (e.g. waterfalls, rivers, oceans)
- Reducing depth of field in very bright light (i.e. daylight)
- 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.
- Reduce the visibility of moving objects
- Add motion blur to subjects
