Most good camera shops should sell them - makes such as Hoya, Lee, Hi Tech, Cokin, etc.I use Cokin filters because for graduated ones their system is easy - web site in link they have outlets in most countries if you click on 'contact us' it has phone numbers and addresses for them.
All makers use same notations for them so look for:
Filter ND2 = 1 F stop less
Filter ND4 = 2 F stop less
Filter ND8 = 3 F stop less
Should have said if you do use Cokin get the p size holder.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies
live;
Their heads are green, and their hands are blue, And they went to
sea in a Sieve.

Yes chelle covers this topic well Polarisers are an effective way to reduce the luminance range in a scene.. They work as they allow light to pass that is vibrating in one direction only blocking the light from all the others, works best when the sky is already blue. They work best on an SLR where you can see the changes in the viewfinder.. Modern ones should be of the circular type.. Dont be tempted to get the linear type whilst a lot cheaper as they render Autofocus and some metering systems will not work accurately

Danny is right, you probably need the circular one. I had the same question a few weeks back and the gang helped me out. Looks like they already covered it pretty well here, good luck!

good morning! i've decided to buy a polarizing filter... but i'm a little bit confused... polarizing filter or a circular polarizing filter... all this filter has the same properties... or i've to see a value? i've found nothing about this... prices starts from 10 to 50... there are some difference? and where can i buy an obscure filter (i don't know the exact name) to extend exposure time? someone of you know a good shop? thanks for your help! may
