Reverse nd filters? Where to buy?

[stephenb]

After a quick search on the net I have only found one site that has reverse nd filters but they are very expensive. Any body know where I can get one for much less than £100.

Reverse ND Grad filters are ones that are start light at the top, then go darker towards the middle, normally used for shots with a very bright horizon (I think)

As far as I know, the only ones available are from Singh Ray and sodding expensive.

I didn't know either. Found out here half way down the page.

Looks like a specialised sunset filter?

reverse ND grad...Foggy you were right:

I have considered the singh ray one but it is £100 which is a bit steep.

I turned my normal nd filter upside down for this shot ( excuse the wonky horizon) and did very little to it other than sharpen resize etc but it is a bu**er to hold in the right place as it tends to fall out of the filter holder.

never heard of them before but a interesting idea but i wouldnt be able to afford that just to try it.

 

[stephenb]

I can't afford it to try it either which is why I am looking for a cheaper alternative.

Couldn't you use a normal ND grad only partially into the filter holder?

a bit of blu tac should stop it going all the way in

Afaik Singh-Ray are the one ones who make a reverse ND...

 

[Caledonia]

Not having a filter set, and probably being really stupid. But couldn't you use a normal square ND grad upside down, or is there some mechanism that stops them being inserted upside down.
