Gray Neutral Density IR Cut Optical Filter for Camera Lens

Product Description

Neutral density glasses with the designation NG offer, as their name implies, rather constant transmission over a broad spectral range, especially in the visible range. The degree of desired filtering can be regulated by using different NG filter types and thicknesses in a specific type of filter. Their use is indicated when the user requires defined attenuation of the intensity of radiation sources over a broad spectral range.

1. Neutral Density filters have several uses and offer the possibility of achieving otherwise impossible results. ND filters appear gray and reduce the amount of light reaching the film. ND filters also do not have an effect on color balance.

Four main uses:

1)   Enables slow shutter speeds to be used, especially with high-speed films, allowing film to record movement in subjects such as waterfalls, clouds, or cars.

2)   Decrease depth of field by allowing wider apertures to be used, in turn helping to separate subjects from their background.

3)   Decrease the effective ISO of high-speed film and allow it to be used outdoors in bright situations.

4) To allow picture and video cameras (which have fixed shutter speeds) to film subjects such as snow, sand or other bright scenes that can cause overexposure.
