Neutral Density filters are extremely useful in video and still photography applications when you want to control light and use lower shutter speeds.\n\n\t\t\t\tCheck out Blackstone filters at http://www.winecountry.camera/\n\t\t\t\tYou can get 15% off of anything in the store by using offer code AOP on checkout.\n\n\t\t\t\tTypically in video you will get the best motion estimation by using a 180 degree shutter. This is double the frame-rate of your video clip. In still photography and landscapes you want to be able to capture motion of things like clouds or water for a dramatic effect.\n\n\t\t\t\tAll ND filters are not created equal. Color casts are a huge problem as are distortions from glass inconsistencies. I use only Blackstone filters for this reason.\n\n\t\t\t\tMusic is from Epidemic Sound.
