Fader ND Filter

time2smile · July 2, 2009

Does anyone have any info on this new Fader ND filters they are selling on Ebay. They seem to cover a wide range of stops.

If you do a quick search, you can find anything previously posted in the Digital Grin forum. Just mouse over "Search" on the bar under the 'logo', and type in the terms you want to search.

I did a quick search for "Neutral Density" because I knew there was a FAQ on the subject. I came across this.

I hope that helps!

Thanks Anthony

But this is not listed in the ND from previous. Its a brand new type that works like a polarizer, you spin the filter to increase the ND effect. from a ND2 to a ND400

Just wanted to see if anyone has purchased one of them, and how they think the quality is.

They are not new. They are usually called "variable neutral density filters." One of the best, from Singh-Ray (among others), has been around for years. Check it out here.

If you go with cheaper, you get cheaper performance. What I've heard is that some can impart a subtl (or not so subtle) color cast to the image. Not such a big deal if you also shoot a gray card for WB, either CWB or afterwards in post.

As for the comment about the search engine. One of the best is google. If you do something like

variable ND site:dgrin.com

you will limit your searches to DGrin. The first entry on the return page is this one. HTH

Thank Scott,

I Seen the filters before, I was wondering if anyone had purchased one, and like you mentioned, what the quality of it is. The Sigh-ray are to expensive for my wish list.

Good you touched on this, if you hadn't I was going to. Yes Vari ND by Singh Ray is one of the best, and because of that, one of the most expensive. I have no personal experience with them, but the reviews I have read have been positive. Ugh, more stuff to add to the FAQ. Thanks for keeping my honest guys, and asking questions.

Also you can essentially make one of these vari filters with a Circ-PL and a Linear-PL threaded together. It has to do with the way they work off of each other, and how the arrangement of the polarizing elements are arranged in the two different filters. So you can supposedly get between 6-8 stops of light control with this set-up. Drawbacks could be vingnetting due to two thick filters stacked. Now you could get around it with a regular Linear polarizer, and a thin circular polarizer, or vice versa.

I've tried this but with two different manufactures of filters. It was a disaster, no vingnetting, but the colors were very cold. It worked as far as cutting down light, but the two different brands, both cheep, the colors went from purple to yellow.

Still want to know if anyone has the evilbay fader nd filter.

thanks all again

Yeah, you probably need to spend some $$$ to do this too. Maybe a Moose Warming Polarizer, and a good quality linear polarizer. Shooting raw in AWB or a custom WB would probably help also.
