I am pretty happy with the Z7 overall but I am noticing that the white balance is a bit greenish compared to the D850.  I have it on auto white balance.  Has anyone else had any experience?

Hi Ulana,

I always adjust the white balance of every image based on a gray (grey?) card reading or something in the scene, regardless of the WB setting I use when shooting.  Out of habit and simplicity, I shoot everything at 5000K and then adjust later.

I conducted a test in my print viewer station when I first got the Z7.  Based on what I can remember, the Z7 did not require a Lightroom tint adjustment when the white balance was at 5000K & a photo of a color checker card shot in the 5000K cabinet.  It's the first Nikon camera that has performed like that - all others have had a strong tint and required adjustment.  Therefore it does not surprise me that the starting point in Lightroom for the Z7 looks tinted as you report, especially if your previous camera did not appear tinted.  Seems like Lighroom is applying an adjustment that is not needed for that camera.

Thanks John

Now that you mention it I also observed that Lightroom is moving some of the sliders at import.  Its not uniform and its not on all images but on most. Normally its the contrast, saturation and sometimes vibrance.  When I double click to reset it to zero it doesn't  -- it resets to this greyed out predetermined number.  

Do you have any experience with this?

Hi Ulana,

With the LR/ACR settings I use, I am able to take control and have not experienced LR overriding my choices.  As detailed in the post https://guerboiscafe.com/forums/tests-and-technique/lightroom-raw-conversions-without-lightroom-color/ , I do not use any of the built in Adobe profiles, but rather than camera matching profile "Camera Flat" along with slider adjustments that give me a good starting point (neutral color & contrast) for Photoshop.

For B&W work, you may also want to look at this article by Ming Thein:  https://blog.mingthein.com/2019/01/14/z7-d850-picture-controls-profiles/ ;  He is experimenting with in-camera B&W processing for reportage and other non-fine art usage.

Attached are my Z7 basic RAW settings and my Z7 camera setup just in case you (or anyone else) is interested.

JM Z7 Basic Adustments
JM Z7 Detail Adustments

JM User Settings Z7

Button Assignments:

Movie Button = Select Image Area (1:1, 5:4, etc) with command dial

OK Button = toggle zoom 100% in both shooting & playback modes

Fn1 = Depth of Field Preview (default position on other cameras such as D850)

Fn2 = Top Item in My Menu (for me this item is Select Non-CPU Lens)

AF-ON = focus button; Focus with shutter release button disabled

Sub-Selector Center = reset focus point location

Other Settings:

AF Area = Pinpoint

Meter Area = Matrix

Delay = 1s

Picture Control = *JM-BW:

  • Tone = BW
  • Sharpening +9
  • Mid-Range Sharpening +2
  • Clarity 0
  • Contrast -3
  • Brightness -1
  • Filter Effects Off
  • Picture Control = Flat

U1 = As Above (BW viewfinder for Tripod Shooting)

U2 = As Above, except Picture Control = Flat (Color viewfinder for Tripod Shooting)

U3 = As U2, except Anti-vibration ON, Delay OFF (Color Viewfinder for Handheld shooting)

*JM-BW is my historical setting for BW viewfinder.  The sharpening, contrast, etc. settings are to provide an optimum live-view/EVF image for manual focusing and also to avoid blinkies on image preview since the camera meter is so conservative.  As a I gain more familiarity with the Z7 I may find that I should use other settings since the live-view/EVF image is superior to other Nikon cameras.

Thanks John.  This is very helpful.  When I import the D850 the default is Adobe Colour with sliders set to 0.  When I import the Z7 the default is Camera Standard and the sliders change from image to image.   

Will definitely take a look at those resources.
