ND Filter Changes Colors - What the Hell!!!!

06/11/2006 12:56:59 AM · #1

As everybody knows ND filters supose to reduce amount of light that reaches camera. They do not change color ballance. Well I was shooting waterfalls today and discovered that it is not true. My ND filter almost completely removed green and truned it yellow.

Both shots are f16 with WB cloudy. First shot had Tiffen ND.9 filter.

Am I doing something wrong or is it just bad filter? Please help.

Thanks

100% sure. Even on filter it says "ND.9"

I agree too. That, or you accidentally hit the WB button on your camera.

I did notice that on short exposure shots effect is less extreme. Still, by looking on with and without shots you can clearly see green being sucked out.

I got 10 before and after shots. It is not WB. Auto WB does remove cast a bit.

Thats an interesting problem...

Warming filters don't usually warm that much. It almost looks like the results of a mild yellow filter. Your filter is probalby mis-labeled and it was a factory mistake. I would return it.

Neutral Density filters, as you know, don't do this.

Tiffen makes an ND9 filter that warms colors. I'm guessing you might have one.

One possibility is that you have a Tiffen Color Grad filter. They have ND9 filters that have a graduated color instead of graduated ND. Look through the filter, does it appear to have a cast to it?

Sure it's not a graduated gold filter you're using rather than a graduated grey?

When I look through it colors look fine. I guess that is why long exposer color shift is so much greater than for short exposures.

Here are 2 more examples of long and short exposure times:

The bottom line is you have a bum filter. End of story.
