Help ,which ND filter do I need?
 

I am new to photography but would love to take some photos of blury waterfalls. I understand I need a ND filter to block out some light so I can have a longer shutter speed, but wich one? I have a Cannon D50. If you can help , Thanks.

the darker the better really if you only need ND and a polariser I would get the screw type

Hoya ND 8 is a good start
someone once mentiond a Hoya ND10 but I have never been able to find one

dont forget the tripod or your in for some very blury water :)

Hi Cutter,

I have a Hoya ND8 (3 f-stops) filter for this purpose and it's great if you have fast flowing water in fairly dull conditions. Check your histogram carefully to see if the peaks are nicely grouped in the middle and not pushed hard over to the right, otherwise you might also need to dial in a little negative exposure compensation so you don't clip any of the highlights.

If you're shooting in very bright conditions you will need to use either a polariser with the ND8 or have one of these fantastic 10 f stop ND filters, because using a slow shutter speed there will be way too much light entering the lens and you'll end up with grossly over-exposed shot.

Hey Thanks its saved me buying the wrong one. Ps owe you a drink

Why not just get all of them by buying one of [URL="http://cgi.ebay.co.uk/Fader-ND-Filter-adjustable-from-ND2-to-ND400-72mm_W0QQitemZ140350820516QQcmdZViewItemQQptZCamera_Filters?hash=item20ad8f90a4"]these[/URL] They are available in various sizes, and having bought one I can vouch for the general quality. Just remember if you do buy one that at ND400 the camera will not be able to meter properly!

That looks a really useful filter Flake. I didn't even know they existed!

B & W do a ten f-stop filter. :D

Flake, I like the variable ND filter but you said you can vouch for the "general" quality... are they worth the money?

Solves My problem

Consider how much it would cost you for a full set of ND filters from ND 2 to ND400, and a bag to carry them around in (I'm sure you can see where this is going!) one filter and you have them all.

Look also at the Singh Ray version of this product, I think they're looking for around $400 for it so I'd say it's cheap. The design is very nice on a 77mm fit filter the element is 82mm as it flares to avoid vignetting. An extra lens cap is included because the normal one will no longer fit.

Isn't a 10 stop ND filter just an infra red one?
