A graduated neutral density is the one that comes to mind..

If there is a waterfall in the scene it will help get that nice silky water effect by allowing a slower shutter speed at a good sharp aperture..

I'd recommend the Cokin "P" system. You can adapt easily to lenses with different filter diameters and avoid buying multiple filters..

An ND or Graduated Neutral Density filter basically just cuts out light, but if you REALLY want the best filter for landscape, consider a (circular) polarizer to make your clouds stand out and eliminate the harsh glare on leaves, etc. One of those also cuts down on light by up to three stops, so it works much like a regular ND filter..

A polariser with a density equivalent to 3 stops light loss? Gosh! That's rather a lot!.

It's not impossible, I suppose.....[??].

However, the darkest one I have presently is 2 whole stops... but vast majority of the polas I have ever used across the years have had a light absorbing effect of....

.... 1+2/3rds stops (5/3rds stop).Regards,Baz..

And this is the primary reason why Im looking to buy a ND filter but Im clueless as to:- how many stops I should consider?- graduated or not?- brand?.

For the "sliky water effect" you do not want a graduated ND filter..

You typically need at least 6 stops of light reduction which will bring a typical bright day subject out to ~1/2 sec to as much as 1sec at f16 ISO 100, the minimum. Obviously you need less light reduction if the picture is taken on a dark day, but you can always up the ISO or reduce the f-stop to get the time you're looking for..

B+W a good brand. They use a somewhat cryptic nomenclature, ND 1.8 (6 stops light reduction) or ND 3.0 (10 stops light reduction). Each .3 is a stop of light. It's a logarithm thing. http://www.bhphotovideo.com/...t/8110-REG/B_W_65066704_52_mm_110_Neutral.html.

Other brands may use the 2X, 4X, 8X......where 2X cuts the light by half, 4X cuts it in half again ie 1/2 the light 1/4th the light, 1/8th the light and you'll see that each of those is the equivilent of 1 stop so an 8X filter gives you 3 stops of light reduction. So you'd need a 12X or 20X filter for a sunny day..

Clear as mud?.
