Why is daylight WB so blue on the D750?

On all my previous Canon, Sony, and Fuji cameras, if I was out in full summer sun, the “daylight” WB setting was really close if not perfect. But with my new D750, it seems way too cool:

Color corrected

I’m new to Nikon, is this typical? Or maybe I have some setting incorrect? I checked the fine tune feature and it’s untouched.

Note: I do have a 3-stop B+W MRC ND filter on the lens at all times.

Please don’t respond with “shoot Raw”, thank you.

Re: Why is daylight WB so blue on the D750?

I suspect that the root cause is your ND filter. The only other answer would be adjustment of the daylight WB default over to blue. Select daylight and move over to the right with the control wheel to check.  I've found auto WB to be more to my desire than choosing a manual WB.

Unfortunately I didn’t take any test shots in the same light without the ND. But I’m surprised if an expensive ND would have that much effect, at only 3 stops.

I'd certainly try it without the filter before jumping to any conclusions.

Check sunlight default color temp as suggested and you can easily and quickly test with ND on/off.  You could have already done it before posting a reply and shared the results.

Re: Why is daylight WB so blue on the D750?

My ND filters (3, 6 and 10 stop) do mess with the WB on my D810 on occasion, not all the time. My D610 acted the same when I owned it too. I have 2 different brands as well, Breakthrough and B+W. The Breakthrough ones seem to mess with the WB more than my B+W filters. Luckily the images have been easy to correct in post so I've never had the need to explore fixing it in camera before shooting.

What 35mm lens are you using, the FX or the DX? If yo're using good glass, putting any filter on is costing you a certain degree of clarity, in addition to (probably) mucking with your colors.

My D750 did shoot a little on the cool side, IMO, but nowhere near as cool as that. In looking at the EXIF data via Adobe Bridge, I see the WB was set to "Daylight" but "Manual" is also indicated, which makes me wonder if the default Daylight WB setting has been altered. I'd check the setting and find out; unless that's what you're referring to as the "Fine Tune" feature.

That, or it's the ND filter as previously mentioned... Easy enough to find out.

You know how to colour correct without using RAW 

While you loose some jpeg file information with a simple colour correction; the loss has not had a significant effect on overall image quality.

Thanks, very helpful article. I never noticed this issue before on my 80D or X100F, maybe they both default to a warmer rendering.

I’m assuming the exposure difference is due to the vignetting mentioned in the video, the camera ups the exposure, and the D750’s auto vignette correction masks the problem.

Re: Why is daylight WB so blue on the D750?

You couldn't shoot that without a ND filter? Seems like the f/2 isn't really giving you that good a background blur. f/2.8 at 1/3200 would have given you the same exposure without the ND filter degrading image quality, and the background probably wouldn't have changed appreciably.

ISO 64 and 1/8000 speed help...oh wait...

Re: Why is daylight WB so blue on the D750?

Like others, I'd suspect the filter.   As others said easy enough to test.  Further, if you did deduce it was the filter it should be easy enough to create/apply a custom WB setting for the camera so you can use the aforementioned ND filter without having to WB correct the resulting .jpg.

Good luck and happy shooting.

There's no shame in using auto or semiauto modes--no matter what the salesdroids at Best Buy tell you.

Unlike you I’m mature enough to admit I don’t know everything about anything, and I’m not going to feel ashamed for asking a question.

I’m really disappointed with the attitudes here.

Let’s see: using “sunny f16”, at f/2 ISO100, shutter speed would need to be 1/6400s. Max shutter speed on the D750 is 1/4000s.

Adding the ND brought that down 3 stops to 1/800s. So the answer to your question is no.

Seems like the f/2 isn't really giving you that good a background blur. f/2.8 at 1/3200 would have given you the same exposure without the ND filter degrading image quality, and the background probably wouldn't have changed appreciably.

I want to shoot at f/2. I shot at f/3 (FF equivalent) for 9 months with the X100F, and it’s not at all the same amount of blur, and I like a little bit more.

Unfortunately, your orginal post sounded more like a criticism than a question - you seemed to be blaming the camera's WB rather than looking for a solution.

Maybe if your title had been "Why has this image come out so blue?" rather than "Why is daylight WB so blue on the D750?". Just a thought

I’m really disappointed with the attitudes here.

Hmmm...

Just out of curiosity, why do you keep a three-stop ND Filter on the lens at all times?
