WebND (neutral density) filters are made to equally dim all wavelengths of light. Think of an ND as a pair of sunglasses with a neutral tint that cut down on the amount of light so that you can take more creative photos. Exposure time was extended to 8 seconds with a ND filter attached. This is the kind of interesting effect you can get. WebA variable ND filter is one that allows you to dial in different settings. For example, rather than being fixed at say 3-stops, it will allow you to reduce light by 3, 6 and 10-stops. The advantage of using a variable neutral density filter is that you will only have to carry one filter with you during your shoots.
