Heliopan 46mm Variable Neutral Density Filter microphone it improves light transmittance whileThis Neutral Density filter makes long exposures easier, by allowing you to change the amount of light passing through the filter by 1 6 stops while not affecting the coloration of the image. This allows for easier selective focus or longer shutter speeds in bright situations, but also provides better close up flash control.
