Capturing professional pictures is now easily achieved with Samsung ND-4 Filter. It ultimately provides greater control over the light entering through the lens, reducing it consistently by up to 25%. This helps reduce problems such as over-exposure, which is a common problem when using slower shutter speeds and bright aperture settings. For this reason the ND-4 Filter is extremely useful when taking pictures in sunny conditions and trying to capture that sense of motion.
