Bought one yesterday to have a play. Who is using them and how/why/what/when? :/

Thanks.

Don't have one but is probably on my very long to-buy list, along with mega-DSLR and ultra-bright lenses

Supposed to help reduce the amount of light coming into the lens which can be useful in a few situations - such as on a sunny day when you want a slow shutter speed (e.g. making water blur in a river)

They allow you to user a wider F/stop and slower shutter speed than the conditions dictate.

and slower shutter speed than the conditions dictate let you shoot blur running waterfalls on a bright day

[EnglishBob]

I have a graduated ND, the top half is grayed out... lets you shoot without blowing out the sky.... never used it though LOL.

[Peted]

Thanks guys, now for some good weather and a waterfall or two.

As for how much

Has some ND filters and prices

[Peted]

Thanks Adam,

I did get one , it is an ND8, should give me about 3 stops.

[Peted]

Some good basic info here too.

The X400 gives 9 stops, thats a lot of stops!

I was at the library studying, then it just *magically* happened that I was sitting at the same row as the photography books.
So I went to have a look, and started reading a book on filters
Does using coloured filters still apply to digital photography? LIke, a yellow filter so you can see the sky? It was an interesting book! After the first few chapters I just flipped through the rest because I had to get back to study.

I think the X400 would be good for really long exposures,
as the page says, its for solar eclipses! oo

" It can also be used to achieve super slow shutter speeds in daylight to render moving subjects invisible.." I saw an example of this in the book today, very cool! one shot they showed how it look with fast shutter speed, then the next was a long exposure with ND filter, and the once busy intersection now looked like a ghost-town.

Awesome, I think I will have to save up for an X400 as well then, sounds amazing. :o
