Neutral Density Filter Wiki
Colorless filters that reduce the amount of light in controlled degrees. (Camera/Lighting)
Represents a measure of how dark the color is. The lightest possible value corresponds to a neutral density of 0.0 and is equivalent to pure white; while the value 3.294 is roughly equivalent to the sum of 100% of each of the CMYK inks and can be interpreted as Registration Color.
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.
device that removes something from whatever passes through it
A screen, plate, or layer of a substance that absorbs light or other radiation or selectively absorbs some of its components
an electrical device that alters the frequency spectrum of signals passing through it
A porous device for removing impurities or solid particles from a liquid or gas passed through it
A device for suppressing electrical or sound waves of frequencies not required
remove by passing through a filter; "filter out the impurities"
A wiki ( ) is a website that allows the easy creation and editing of any number of interlinked web pages via a web browser using a simplified markup language or a WYSIWYG text editor.

A website that allows collaborative editing of its content and structure by its users
Wiki software (also known as a wiki engine or wiki application) is software that runs a wiki, or a website that allows users to collaboratively create and edit web pages using a web browser. A wiki system is usually a web application that runs on one or more web servers.
Early morning twilight in Bergen, Norway. The blue hour.
Long exposure with a 3 stop Neutral Density filter (B+W ND103).
Exposure: 30 sec, f/16, ISO 200. D300s on tripod with remote cord.
View towards Vagsbunnen, the end of Vagen (the inner harbour of Bergen). In the back Mt. Ulriken and Mt. Floyen.
Best enjoyed large and on black by pressing "L".
landscape photography essential tool - graduated neutral density filter
why can't I just point and shoot the sunset like I'am taking my other photos? :-)
Because of dynamic range needed to record both sky/sun and ground is almost 14 light stops and your digital camera can record only 8 stops.
Graduated neutral density filters helps to stop down sky and with it camera sees "compressed" range at the same exposure.
