Neutral Density Filters

Photos taken using a neutral density (ND) filter, usually to achieve a longer exposure time in daylight.

Please only add photos taken with an ND filter, and comment or tag so we can see what density of filter you're using. I've also restricted posting to 5 a day just to stop anyone fly-tipping. Other than that, no rules! :-)

Also check out the Urban Neutral Density group. Feel free to post to both.
