Yes
On a few of my shots I took on hol for example a dark cliff and bright sky have problems exposing correctly. Either the sky is overexposed or the cliff is underexposed.

As I understand it (maybe wrong) a standard ND filter reduces the light equally so that wouldn't really help as the problem would still occur?

A grad ND filter would solve this? if it can be rotated to allow less light in from the sky and more from the bottom of pic, the cliff in this example. Or is it just graduated in that way anyway i.e less light at the top more at the bottom.
 
Yes an ND grad would solve this as the holder that the ND grad fits into can be rotated in any direction.
 
The holder? Like on a cokin system do you mean. I was thinking screw the screw on type.

Looking at filters on the net it's not obvious to me which are graduated or not.
 
Grads are usually for Cokin P or similar as the light dark boundary could be anywhere in your shot. Grads are rectangular so you can slide the filter up/down in the holder to position the junction where you need it.

edit. pictures always help...

You can get screw in ones, but I dont see the point, as you are set to having the gradient half way down every shot, with the Coking (etc) systems you can adjust where the gradient is and get a much better result, in my opinion.
 
Cheers for the pic Robert.

See where your coming from with the Cokin filters now.

I can see that being much better, say if the sun was on the right and lower down for example.

Seems the screw ins are only really suitable for a set senario.
