The filter features an even, neutral gray color for creative photography applications. ND4 filter offers a 2-stop EV value which allows you to slow down the shutter speed or use a larger aperture in bright light conditions. Neutral Density filters have their unique applications and offer the possibility of achieving otherwise impossible results. ND filters reduces the amount of light reaching the film/CCD. The filter is double threaded and thinner than a standard filter to minimize any possibility of vignetting when used with a WonderPana 145 filter system. The optic is coated to correct for color balance as well as minimize reflection at the filters surface; therefore, reducing flare and ghosting. Fotodiox ND filters are neutral grey and do not color cast the images.
