67mm NDX Variable Range Neutral Density Fader Filter Adjustable from ND2 - ND1000 for Tamron 16-300mm f/3.5-6.3 Di II PZD Macro

The Variable NDX Fader Neutral Density Adjustable Variable Filter (ND2 to ND1000) - Neutral Density (ND) filters can reduce the intensity of light without appreciably changing its color. Classic ND filters have different f-stop reduction numbers and transmittance thus generated can be applied for different shooting conditions, such as portraiture, waterfalls, fountain etc. This Variable Neutral Density filter reduces intensity of all wavelengths or colors of light equally, giving no changes in hue or color rendition. The purpose of standard photographic neutral density filters is to allow the photographer greater flexibility to change the aperture, exposure time and/or blur of subject in different situations and atmospheric conditions. 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 Filter Features:Neutral density can be adjusted from ND2 to ND1000. It is easy to create different neutral density by rotating the ringApply slow shutter speed under strong sunlight exposureLarge aperture is available to create depth of field easilySuitable for dynamic screen, waterfalls, streams, waves, etc.Index marks on the edge of filter for exact adjustment.
