Fotga 82mm Slim Neutral Density Optical Grade ND ND1000 Filter for Digital Camera Lens from FOTGA
- Instead of reducing the aperture to limit light, the photographer can add a ND filter to limit light, and can then set the shutter speed according to the particular motion desired and the aperture set as needed. Using a digital camera, the photographer can see the image right away, and can choose the best ND filter to use for the scene being captured by first knowing the best aperture to use for maximum sharpness desired.
- Examples of this use include: Blurring water motion. Reducing depth of field in very bright light. 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. Using a wider aperture to stay below the diffraction limit. Reduce the visibility of moving objects
- Package including: 82mm ND1000 filter x 1
- Make sure this fits by entering your model number.
- The shutter speed would be selected by finding the desired blur from subject movement. The camera would be set up for these in manual mode, and then the overall exposure then adjusted darker by adjusting either aperture or shutter speed, noting the number of stops needed to bring the exposure to that which is desired. That offset would then be the amount of stop needed in the ND filter to use for that scene.
- Add motion blur to subjects Neutral density filters are used to control exposure with mirror-lenses catadioptric optics, since the use of a traditional iris diaphragm increases the ratio of the central obstruction found in those systems leading to poor performance. This Ultra thin ND1000 Filter can effectively weaken the light. ISO setting in the same aperture can reduce. The ultra thin frame to help avoid the vignetting on super wide angle lens
