"ND" Filters
-
I regard myself as a born again photographer ie. it’s been a hobby of mine for the last 25 years but it had to hibernate while I got married, kids etc, but, in all my time dabbling I have to be completely honest and say I have never haerd of ND Filters!!!
Can someone explain to me (in baby talk please) what they are and what they do and where or when you would use them. Sorry if it’s a “moron”question.
Heres a link from a company called Cokin, a well known manafacturer of ND (Neutral Density) and many other tpes of filter.

This seems to be a reasonable straightforward explanation of how they work.
Thanks Tadgh, so, they limit the amount of light (but don’t alter the colour) coming through the lens, allowing you to take longer exposure than normal??
Then theres ones called Graduated ND filters. which look like this http://www.bobatkins.com/photography/tutorials/digital_filters/grad_nd.jpg and these are for taking good sunsets. Because they darken the sun whilst allowing a normal exposure of the foreground.
I am relatively new to this too but i want to get more into it and have been doing a bit of research on it. (I have a Cokin filter system winging its way to me from Hong Kong thanks to ebay). This might help. http://en.wikipedia.org/wiki/Graduated_neutral_density_filter
Hi Chris,
This ND chart will show you how using various strengths of ND filters will affect your exposure time.

A common use would be in landscape & nature photography to show movement. I used a 10-stop ND filter for the following image:

Without the filter, the exposure time would have been about 1/4s, but with the filter the exposure time was 4 minutes.

i’m new to a lot of this and this questino might sound silly but how would you attach these filters . ive been trying to take moving water pics and from what ive read an ND filter would help with this.

Sinead you can get the screw in type that go on the front of your lens but these are fairly limited
The best type is to get the one which use a holder which attaches to the front of your lens with an adapter ring that suits your lens size,You can get a new set of say cokin (holder,3 grads and an adapter ring)for around 50 quid
