Hey all~
While I have been able to find many regular ND filters I have not been able to find a place I can purchase a gradient ND filter (screw in, ND2 or so). If anyone could point me to a likely place I would be greatful. Thanks.

Where do you live?
Word of warning, don't get a screw-in. They are poor and rubbish. With a screw in your gradient will always be in the middle, which causes / forces the photographer to level the horizon in the middle which isn't very nice really.
Best off getting a Cokin holder and filter - they are great and not enough people use them. With those, you can pull it up or down depening on your horizion.
Just go into your local camera store, or order from the net, they are evrywhere.

Thanks for the tip -- I was just about to order a 77mm 0.6 ND grad, a screw-in type, but I'll give those Cokin things a look first

Helgi,
I haven't used an ND for many years, but it was a regular part of my Architectural arsenal. Jon is correct: don't even THINK of getting a screw-in ND, go with the Cokin. Not only can you slide the filter laterally to position the gradation properly, you can rotate the holder so the gradation runs diagonally...

I'm a fan of the ND filter:
I had a screw-in, which was great but I now use the Cokin A system which is also fine. It allows combinations of filters but I've not tried that.

Go to ebay and pick yourself up a few second hand cokin filters to give them a try out first. I got a set of 8 or 10 grads of various strengths and colours for less than 10 quid (GBP)

there is one screw in ND filter that is adjustable but is $350....so I would go with the Cokin version...much more useable and variable in my opinion. Good article in Outdoor Photo either Nov or Dec on ND filters. |

Have you seen any good examples of a graduated ND? All the ones I've seen look like they've been filtered which, for me at least, kills the vibe a bit.

I have seen many examples where you could not tell...it is all in technique and picking the proper filter. Positioning the graduated merge is the most important in making it unobtrusive.
There was an excellent article on using ND filters in Outdoor Photo in the Nov 04 issue...It is called SPLIT NEUTRAL-DENSITY MASTER CLASS by Glenn Randall. He goes into picking afilter...determining which one to use whether a +1, +2, +3, etc...and how to meter your shots to determine filter strength and how to place the split so it is not noticeable.
Good luck... and here are some other sources of info
Creating a ND Filter with GIMP
Using ND Split Filters
Guide for using split ND
Photo Filters for Color Photography
You might be able to find a back copy of Outdoor Photo...I dont have a scanner or would scan the article for you...and I checked the webpage but I could not find it posted.

| Thanks for the info... the cokin system looks a bit more promising than the screw on type; guess i just had to know what to look for. |

Used a grad ND Cokin filter. Had a screw on and it was terrible. Cokin is a little slower to set up, but gives better results. Cokin is not good with wide angle lenses, the holder is relatively far away from the lens and will show up in the sides and corners of your photo. |

| I'm having a little trouble understanding all of this. The only lens I have for my Canon 10D right now -- and probably for the next few months -- is the Tamron 28-75mm 1:2.8. I want to get a neutral density filter and a graduated neutral density filter. After reading this thread I found the Cokin holder & filters at B&H, but there are so many options. Can anyone tell me exactly what I need to get so I can use it with what I have? I don't understand all the A series and P series and adapter ring stuff. HELP! :) Thanks in advance |

| Oh, and when I bought a UV guard for my lens I had to get the 67mm one. I don't know if you need that information or not. |

| Btw, don't forget to look at ebay for cokin stuff, there is a lot of various filters and holders there. Not a whole lot of difference compared to b&h, but still, a few bucks there and a few here can easily add up. |

I would suggest calling them, I am sure they would help.
It appears that you need to get an adapter to fit your 67mm ring that attaches to the Cokin filter holder. So you need two pieces, the adapter and the filter holder. Plus of course, any filters you may want. |

| Thanks, Paige. I guess I trust my fellow photographers more than I trust a salesperson ... but you have a good idea. I shall do that :) |

As far as I know, A series is for lenses up to 62mm filter thread, P series for up to 80-something mm. and X-Pro series for giants.
You'll need the filter holder, which holds up to 4 filters (and coupling ring if you intend to stack more filters), adapter ring the size of your lens' filter thread and the filters you want. Adapter ring is screwed onto the lens, and holder is attached to the ring.
I recently ordered P series holder, 3 adapter rings for each lens I have (58mm, 62mm and 67mm filter thread sizes), one circular polarizer and two grad. ND filters; 121M and 121S (2-stop and 3-stop respectively). |

The Cokin A series is typically for lenses with diameters between 36 and 62mm and the P series is for wider angle zooms and diameters between 48 to 82. For your 67mm diameter lens you would need the P system.
To start you need the cokin P series holder. You then need an adapter ring, which will connect the holder to your lens. These come in various diameters and you need to get a ring for every different diameter size. If you only have the one lens then you only need to get the 67mm adapter ring. You screw the adapter ring onto the lens and then slide the holder over the ring. The holder then gives you 4 or 5 (I think) sections where you can add filters.
The cokin system has a lot of different filters, most of which are probably pointless or something you can replicate in photoshop. I have the G2 graduated ND soft, which means the line between light and dark is softer and doesnt show as obvious in the image if the horizon isnt straight. You can also get a hard filter with a more distinct line.
Yup, I'm slow!

| Yeah! Thank you! Just what I needed to know. I don't think I'll use much more than the ND and the GND -- but thanks about the tip about the soft GND. |
