It won't affect color (hue/saturation).

A Neutral Density filter is neutral, in that it doesn't have color. It's as if part of the scene were taken with a couple (depending on the filter) stops down.


That is correct. However, the Cokin filter in question is actually a "graduated grey" not a "graduated ND" - certainly a number of people at photo.net and other places have suggested that the Cokin grad grey does have a slight colour cast.

I stand (or sit) better informed.

Any update on this stuff? I ran across someone's portfolio online that shoots here in Washington and Oregon. His stuff was amazing and right up my alley and he says his favorite filters are his grad NDs. Believe me, I spent an hour yesterday tracking down his shots on Google Earth from clues in descriptions etc as best I could.

So a few final questions:

1) I'm assuming the grad ND are the same in their labelling. (ie. .9 is 3-stop, .6 is 2-stop).

2) Brent, for those three shots you showed, how many stops do you have. That's actually a little extreme for what I think I want. I'm thinking my typical seascapes with long exposure and want to more easily bring the sky into line. I've also always shot at dawn and just thought about switching to dusk (which on the left coast would mean sunset in the picture).

3) I'm thinking soft edge even though the horizon on seascapes is about as level as you could get. I just think the hard edge would limit them too much. Am I wrong on this?

As I'm off on my holidays soon I coughed some more pennies for a Lee .3 & .9 to complement the .6 I already own. A guy at Robert Whites told me that a soft NDG might be too subtle for a digital cam??? OK, they are expensive, however @ 150mm x 100mm I get the NDG and ND as the graduated part will cover a 77mm lens. With the 3 filters its possible to have from 1-5 stops. Even with the slim holder I got a little vignetting @ 10mm on the 20D (handholding might be a good idea for super wide).

There are hard and soft edge grads as well as an all round. The cokin filters are of the all round type and suite most people.

The nature photog leading a workshop I was on uses the hard and soft edge grads. The hard edge where the landscape will be able to hide the line of gradation and the soft edge for landscapes where a more subtle gradation line is required.

I own this exact one and it does rotate just like a circular polarizer.

I use the .9 3-stop one the most I think, but a lot of the times I stack them to get 5 stop grad.

Cokin is poor quality plasic. I broke mine.

Now I got a full set of Lee ND grad filters, with the Lee Foundation system.

There's one problem with the screw in grad filters. You can't adjust where the grad line falls, only the angle.

That's why get Lee. They're 4x6 and you can slide them to the exact position you need.

The OP was wanting the screw in type so just pointing out the drawback.

My bad.

I used to use an ND filter all the time, but after it "graduated" it got upity and now won't have anything to do with me.

Are there multiple types of Lee systems to mount the Lee filters onto?

I want to get several of the Lee Graduated ND filters with different stops, and I seem to remember seeing different holders. Which one should I get considering that I have nothing yet.

If it helps, I'm using a Nikon D70 with mostly:

1) Nikon 18-70 that has a 67mm front end.
2) Nikon 70-200VR that has a 77mm front end.
3) Tokina 12-24 that has a 77mm front end.

Edit for typo

All you have to get is the adapter ring for each. I would recommend the wide angle ring for all sizes.

You need adapters for each lens, those are cheap. :)

I've got two adatpers, 6 ND filters, polarizer (100mm) and the foundation kit. It was over 1000USD, but it is well worth it.

Does the adapter ring that you are referring to allow for the vertical adjustment of the position of the filter?

What is the foundation kit? Is it necessary or something that I'm going to want too?

I have a sky set, a blue grad 1,2,3, sunset 1, 2,3, nd grad soft .6 & .9 and the bellows shade.

I actually have a second holder I don't use for parts.

My goal for now is to filter to adjust for blown out skies in landscape/seascape shots. After doing a little research since coming across this thread this evening, this is what I think will need:

1) Neutral density soft grad set that includes a .3ND grad soft, .6ND grad soft, .9ND grad soft, and a storage pouch.

2) A Lee filter holder that holds 100mm (4") wide filters regardless of length.

3) Two wide angle ring adapters for the two sizes of lenses that I use the most: 67 and 77mm.

Does this sound about right? I'm ready to order if it is.

I would get a hard grad for the sea. I wouldn't bother with the .3 and a storage pouch will be for each one. You might think about a sunset or a grad blue for skies.

Does anybody actually clear any money at their profession? Sometimes you guys amaze me with all the stuff you have...

Oooh some kit! the bellows shade is mega bucks, does it really help?
 03/29/2006 07:48:18 PM · #49
Thanks Brent. I will adjust my shopping list from the set of soft grads to individual filters. .6 and .9, one each in soft and hard for a total of 4.

Is there any real advantage to using a sunset or grad blue over post-processing?

To DrAchoo: Business has been good this past year but I'm not able to spend carelessly yet. I just want to round out my collection before I go on a photo trip to the Dominican Republic in a couple of weeks. I'll still be shopping wisely (hence all the research). I'd like to make money at this someday and let it pay for itself.

I've been aquiring gear for over 10 years!

I've had most of my lee filters since '97.

Pretty much most of my cash goes into equipment still. I'm almost at a point where I can quit buying and have things covered.

The Blue is nice but can be added post process, it does had about a stop of exposure control.

The sunsets I find are easier to shoot then to add later, since they are 2 colors blending together.

You could always shoot a bunch of exposures and blend them in HDR and forget the ND grads...
