Lightroom and Z6 Raw Files

Recommended Posts

My observations with the Z6 and Lightroom CC.  Applies to Camera Raw as well.
 
LR produces very nice images with Z6 files and there are some big differences in how Adobe handles Z6 .NEF files.  In the past, when you set Adobe Defaults for a camera, you get a color profile of Adobe Color, all basic adjustments zeroed and sharpening of 40/1.0/25/0 and no Noise Reduction.  With the Z6 and Z7 you get an Adobe Camera Profile matching the one used in the camera, some interesting sharpening values and noise reduction that varies with subject and ISO.
 
When opening a Z6 / (and downloaded Z7)  .NEFs in LR Classic CC 8.1 or LR CC Desktop (At Default Adobe Settings)the camera assigned profile is retained, Exposure, Contrast, Shadows, Saturation, Sharpening and Noise Reduction varies depending on the in camera settings.
 
Active D-Lighting: In general, any Active D-Lighting will yield a Shadows Adjustment of +0.1 ADL Normal will cause a +0.33 Exposure Adjustment and ADL High will cause a +0.67 Exposure Adjustment.  This is consistent with the camera slightly underexposing to protect highlights when ADL is used.
 
Picture Controls:
 
Standard yields the Standard camera matching profile in LR.  Sometimes with a minor change to saturation.
 
Auto will yield minor changes in contrast and sometimes Saturation.  Auto yields the Standard camera matching profile in LR as well.
 
Custom Picture Controls:  Any changes to contrast in the in-camera settings for the picture control will yield a change in contrast in LR.  Standard with a -1 Contrast in camera seems to yield a -0.24 contrast adjustment in LR.
 
Sharpening:  Lower ISO settings seem to yield something like Sharpeniing 40 / Radius 2.0 / Detail 25 / Masking 0.
 
Noise Reduction:  Noise reduction values yielded in LR vary based on subject and ISO.
 
Observation:  A well exposed JPEG with Standard or Auto Picture Control and ADL off or Low yields a fairly nice .NEF conversion in LR.  ADL High and above, not so much.
 
White Balance:  ARGGGGGHHHHHHHH!   Z6 / Z7 .NEF and Fuji XT3 .RAF files yield wacky Light Balance Values in LR.    Tint values of -30 instead of +10.  If you try an Adobe Daylight Preset you will get bleah results.  The original Profiles are calibrated against a different standard.  I was able to download a set of V2 profiles for the Z6 from Adobe that help somewhat.  After you change from the starting profile to one of the V2 profiles, the Tint calibration seems to work as it used to.  The rint calibration issue also affects custom profiles created with X-Rite software as well.
 
The white balance issues are not a show stopper, but they are clumsy to deal with and make a custom x-rite dual illumination profile pretty much useless. Also, creating a preset in LR CC Classic with a V2 profile will not properly apply it to images.
 
It will be interesting to see how Adobe deals with the new process 5 profiles they have created.  I am sure many of their developers are considering other less complicated careers at this time :)

I recall the default Nikon camera profiles causing me (and others) a lot of consternation when I first started using Lightroom. The images would look great for a few seconds after importing, until Lr built its preview, then they would go flat and lifeless. Good to hear things are improving.

Aperture did the same - you would initially get the embedded JPG preview but then it would take you to a rather flat RAW which needed a bit of work just to match the JPG.

 

At least I don't see that now with Capture 1 and the Fuji RAWs.  (I'm only using the Fuji version at the moment, so can't comment on what it might do with Nikon RAW).

The latest release of Lightroom has a new feature to "enhance details" which apparently does a different demosaicing of the Fuji X-trans files, as well as all Bayer patterns. There are also many new profiles that one can apply on import. Lightroom has certainly come a long way in the time that I started using it, and I really couldn't live without it, but man... it's just always so slow to start for me.

Do you have all of your images in the one catalogue Dallas? If you switch the machine off and clear the cache then the whole lot has to be loaded again which takes time.

My iMac is much faster since I have been using an SSD for storage and I only ever 'sleep' the machine rather than switching it off.

I used to, Mike, but at the beginning of the year I started a new catalog for the first time since adopting Lr as my primary editing software. It hasn't really made much difference to the start up time though. I do believe that the issue for me has something to do with the Adobe CC Desktop app. That has crashed twice this month and had to repair itself. It's possible that either it isn't working correctly because of an issue that is related to Adobe's servers and my ISP, or something to do with inefficient coding. I mention the former because in the past I have had some big problems installing updates to the programs. They would get to about 3% and then just stall. Some digging online revealed that this is common with many other users too and had something to do with the Adobe servers not responding properly to packet requests from certain networks. When this happened to me the first time a couple of years ago the online support literally asked me to change my ISP. I told them in no uncertain terms to change their servers. They then had to manually install the updates from an alternative server. I watched what they were doing as they took control of my Mac. Hilarious, I know...
