Grad ND4, especially if you're using digital. Check out the september 2006 issue of Practical Photography for the reason why. :)

I have both Cokin Gradual ND4 and 8, I use ND8 more than 4, because the sun/sky light in Singapore is too strong, ND4 won't be able to bring out as much blueness from the sky like in other non-equitorial countries.

get a reverse sharp edge grad ND, 2 or 3 stops. in fact i wonder if commercially they have 4-5 stops, if there are, i may buy more. very useful in landscape, travel/building. in your case, sunset (over the sea). if over the mountains, not so useful and got to use soft edge.

for many more stop, try stacking filter, I tried and it works. Not sure how much it affected the image quality though :sweat: .

I think Singh Ray has, but I recall its incredibly expensive, almost 300usd.

graduated refers to the graduation of density that goes from very dark to almost clear. so sharp edge and soft edge refers to the transition. sharp means the transition is over a small area with most part of the dense part dark (e.g. 3 stop) and only the small part of it changed from dark to clear. soft means the transition area is bigger. reverse means that the darkest portion is in the middle, with a soft transition to less dark density towards one end, and with a sharp edge transition to clear joining the clear half of the filter. this is better for seashore sunset where the horizon is straight and the sunset gives the brightest highlight in the middle and that is where the darkest density will help to bring down and even out the exposure.

as for product ref no, pls dun ask any forumers for that. i dun think that anyone would know it at the back of their mind, unless they search specifically for it, which you can do the same thing. go to my thread in my signature, or just search for some online retail site, they might have it.

I use Lee 0.45 ND Grads both soft/hard and they work as advertised. Its neutral and doesnt give nasty color casts like the Cokin ones which is painful to remove. I would recommend the 0.45 and 0.6 ND Grad for landscape enthusiast. Cost about $165 each. You can get them at Cathay Photo.
