ND Filter
A type of filter that can be attached to the lens. This adjusts the amount of light that enters the lens without affecting the picture color.
ND = near distance H = hyperfocal distance D = distance focused upon F D = far distance EXAMPLE: What is the depth of field of a 155mm (6.1 inch) lens that is focused on an object 10 feet from the camera lens using f/2.8?
ND-graduated filters are half clear and half tinted. They are used to reduce exposure in part of the frame in scenes when exposure range of the subject is too much for the film to handle.
ND Grads need to be positioned very carefully to get the best effect. They need to be slid up and down in the filter holder with the transition from clear to dark falling accurately on the horizon or the light sky where you want to obtain a correct ...

ND filters, or Neutral Density Filters reduce the amount of light that gets in the lens in a balanced way (as opposed to a polarizing filter, for example).
ND Filter
When you use a Neutral Density (ND) filter on your lens, it allows you to optically cut out the amount of light going through the lens, but otherwise does not [ideally] affect image quality.
ND filters are just another way of affecting exposure, so it should come as no surprise by now that they're measured in stops. How strong a filter you need depends on your requirements.
ND is an abbreviation for neutral density.
Near ultraviolet are wavelengths from about 400nm down to 250nm. Most photographic emulsions are sensitive to this range of bands.
"ND grad" is short for a graduated neutral-density filter. Grads are used to give far better results in one shot than the results from tedious, and usually ugly, HDR.
Grad ND filters are used when the dynamic range of a scene exceeds the capabilities of the camera (film or digital) to record detail in both the brightest and darkest part of the scene. The go from clear on one side to a neutral .6D (2 stop) or 0.

Ten-stop ND Filters are a useful addition to the landscape photographer’s kit bag.
The Vari-ND is relatively thick and can't be used on extremely wide-angle lenses on full-frame digital or film cameras.
Neutral Density (ND) filters are sunglasses for your camera. They reduce the amount of light coming in without changing the color.
Neutral Density (ND) refers to a filter, usually colorless or gray, that affects only the intensity of a light source.
Neutral density (ND) filters are simply filters which block a certain percentage of light from passing through. In other words, they're darkening filters.
To use a graduated ND filter properly, there are a few keys to keep in mind. The most important fact to remember is to use the DOF preview button to accurately position the dark part of the filter over the light area of the image.
Neutral Density (ND) Filter
Filter for use in front of the lens that absorbs all visible wavelengths to a more or less equal extent. ND filters can be used with both monochrome and color films, since they have no effect on color balance.
A Neutral Density (ND) filter creates a reduction in light that is neutral and equal for the film or sensor area.
Neutral Density, ND (Gel)
Those .3, .6, and .9 ND gels reduce light Intensity by 1, 2, or 3 stops respectively, without a change in color or quality of the light.
A colored piece of glass or other transparent material used over the lens to emphasize, eliminate, or change the color or density (ND) of the entire scene or certain areas within a scene. Also see "colour temperature", "UV".
While the aforementioned ND filters are a necessity for any serious landscape artist, be cautious when considering the purchase of a UV filter. Generally these filters don't provide much impact, and can in fact reduce the ultimate image quality.
9 soft edge grad ND filter. This is also known as a three stop ND. It blocks three stops of light on the darker portion of the filter while letting the normal amount of light pass through the clear bottom portion. The filter on the right is a 1.
While there are sophisticated mounting systems for an ND filter, you can simply hold it in front of the lens, or use gaffer's tape to keep it there. Left your filters at home?
Is there a different ND filter I could have used to reduce the exposure without adding tint?

ND filters are available in a range of strengths. Again, I recommend 0.9, which reduces the power by 3 stops. It's better to over-reduce and turn the power up than to carry a stock of different filter strengths.

The "exposure triangle" omits a fourth factor - LIGHT! Yes, light can be controlled. You could reduce the light by using a diffusion panel (or an ND filter). You can increase light by adding light sources.
