What is ND???

Thanks

Neutral Density

Cut´s off the amount of light coming in, without colouring the light.

Someone else might jump and give the proper definition in proper english.

ND
 

Thanks for the help, I'm new to this.

Ken,

Neutral Density filters, which come in different grades (0.1; 0.2; or, 1/4; 1/2; etc.), are used to cut down the light that is entering the lens. There fore, you can adjust the depth of field, without changing your camera speed:
Less light into the camera, the more you have to go to an f stop that provides a shallower depth of field. Such as from f8 to perhaps f5.6, or, f4.

Many times, such as when I shoot in high mountain areas, my XL-1s will notify me via the view finder, that there is too much light. I therefore switch in the built in ND filter.

In studio, it is an excelent way to separate the subject from the back ground with the afore said shallower depth of field.

As Federico mentioned, they do not change the colour's entering your lens, just the amount of light.

I hope this short note is of some use to you.

IF you get an ND Filter (aside form the one in-camera...) get a GRADUATED ND. You'll be gald you did!

John, do you know if the Nikon 52Mm Filter Nd4S is graduated? Can't seem to find out.

I liked the description that ND is "sunglasses for your camera"
(ie, it lowers the amount of light entering your camera for all sorts
of reasons (using sweat spot of your lens, decrease Depth of Field etc.)
