polarizer issue
I find that when using my circular polarizer on my DSLR's, it not just darkens the sky and colors but the entire image drastically!!! Like shooting through a fine black screen and also underexposed by at least one stop! I have tried overexposing with no luck as the camera is doing it with TTL. I almost get the same result using the camera's optimize image setting. I have a $220 Singh-Ray, $150 Nikon and a $100 B+W to work with, so it is not the brand. I am using the D2Xs and D200 with the 17-55mm lens and 70-200mm 1:2.8 mostly. It CAN and HAS to be corrected in Nikon View with the auto contrast to brighten it up to "film quality" for lack of a better term. When using my N80 and N90 I never shot without a polarizer with perfect results!.

Is this a white balance or exposure comp issue, or both?KyleJ3..

If you haven't yet, ask over on the Nikon forum..

This makes no sense to me as the camera should account for the decrease in light that you get when you add a polarizer, about 1 stop.A member of the rabble in good standing...

It's not a WB issue. Unless you are shooting in Manual Exposure mode, your camera ought to be able to automatically double the exposure time to ensure a correctly exposed shot. Your viewfinder will show a darkened image, regardless, but the image you capture ought to be correctly exposed..

That's odd..

I regularly shoot with a CPL (B+W or NIkon CPL II) on the D2x with the AF-S 17-55 and I have never had that happen. I always shoot on manual but take the camera metering as a guide and adjust according to the histogram. I find it is never far off, even with a polarizer..

What metering mode do you use? Has it accidentally been set to spot metering?..

Go buy as D40 with the kit lens, and a Tiffen polarizer of the right size..

Set the camera on P for program, at ISO 400..

See if this works..

Once you learn it does, you can transfer the sceince to your expensive cameras..

I use the matrix setting alot and have tried spot to see if there might be a diff. Both cameras do it!! It is just an overall darkness that is not really underexposed, but no other way to describe it. Lots of saturation even on the less contrast mode in camera which I normally use or on auto with direct sunlight W-Balance setting for outside in the sun at noonish. It was a beach shot too that was darker than what I think it should be! Overexposing just washes out white detail.KyleJ3..

Your a smart guy, ha? Is that camera more expensive??? It must take better pictures, ha???? This is why I put in in beginners questions to dig up the smart people who answer stupid questions!!!.

What does the "P" stand for anyway???.

The "S" means sh_t,the "A" means as_hole,the "M" means "I'm the MAN,but the "P" ??? POO-POO maybe??.

Thanks for the science lesson dude!!! A D40 ha? How's about the 30D? Is that close enough? My Nikkor 17-55mm lens just won't screw on to that one!! Any advice??? Been trying now for over a month with no luck. Thanks again for the class!KyleJ3..

Your problem seems a little odd, in that the metering does not account for the approx. 1 stop cost of the polarizer. Are you quite certain that you have circular "C-PL" rather than linear "PL" polarizers? A long shot - how about re-setting all camera settings to factory default? This seems to work sometimes when logic doesn't .

Sorry that's all I can think of, but maybe you could get a better response in the D200 forum..
