• The ND400 should be used if you need to substantially reduce the amount of light, such as when taking a photograph of the sun.
• It is also used to create different effects from what we actually see
• With a slow shutter speed.

ND filters reduce only the amount of light without changing the colors, and offer an alternative light-amount adjustment method to the adjustment of aperture or shutter speed.

Please feel free to ask if you have the product which I do not list.I will do my best to provide at competitive price.
