  • (ND Filters) Neutral Density filters can be attached to the lens of a camera to assist in preventing overexposure of an image. Prosumer camcorders have ND filters built in.
  • In photography and optics, a neutral density filter or ND filter can be a colorless (clear) or grey filter. An ideal neutral density filter reduces and/or modifies intensity of all wavelengths or colors of light equally, giving no changes in hue of color rendition.
  • A filter that attenuates light evenly over the visible light spectrum. It reduces the light entering a lens, thus forcing the iris to open to its maximum.

Ok,thought i'd have a go at some long exposures while away last week,but as I dont have the necessary funds lying around for a fancy big stopper filter ( ;) ),I opted for a slightly cheaper version,a shade 8 piece of welding glass for a pound that I sourced locally! lol .Found an old cokin filter holder I had,took out the 77mm screw in piece and glued it to the welding glass!,it does the job!!,lol. Worked out the density of it,seems to be about 11 stops,so I worked out the exposure time using an ND calculator app. that I found for free on itunes.I dont think it turned out too bad,would appreciate anyones opinions, Cheers, Chris. Tech. info- exposure 223seconds @ f13-iso 100,sigma 10-20mm lens at 18mm,converted to b+w in photoshop.
