Hi Rui,

Rex is right. If there is bright sunlight then a 10 stop filter would be the one to go for, as for which make that all depends on what your budget is for one ???
Another thing with the 10 stop is when the light isnt bright, exposures can run into several minutes (6 plus) so its always wise to have a selection.
I currently have a 3 stop, 4 stop and a 10 stop as well as a set of ND Grads that i can use if need be.

If there is any other questions please ask.

Thanks a lot for your replies Rex and Rob. will get the 10 stops ND.

In our local market we get B+W, Hoya, Kenko, Marumi, Matin, Hamma. The B+W is way to expensive for me. Any particular one i should consider?

Im not sure Kenko, Marumi, Matin or Hamma actually make 10 stop filters. I know Hoya do a 9 stop ND (Hoya ND400 i think its called)
Ebay may be the best bet ?

Thanks Rob. i think ebay will be best bet for me.

The only ND filter i can find is Hoya and its only 3 stops. There is something called a Phottix ND variable filter available at some local stores. Adjustable to 10 stops but the cost if very high for me to afford.

The cheapest 10 stop filter that is avaliable on the market is the hitech one. Its still around £70.00 though, unfortunately they arent cheap.

Have a look at this variable ND filter by Polaroid.
http://www.amazon.co.uk/s/ref=nb_sb_ss_i_3_16?url=search-alias%3Daps&field-keywords=polaroid+variable+nd+filter&sprefix=polaroid+variabl%2Caps%2C184

They're a bit cheaper than other filters but if they work and don't degrade the image too much.........

I think they're definitely worth a look.
