When setting the WB of a smart preview (original placed in an external HDD and disconnected), the photo turns turns very greenish.

I have been able to reproduce for Sony A7III raw files with 2 specific lenses (with a different lens it works fine):
- Sigma 50mm F1.4 DG HSM Art 018.
- Sony FE 25-105mm F4 G OSS.

Steps:
1. Import Standard + Smart Previews.
2. Place original in external HDD.
3. Disconnect HDD.
4. Select photo and develop.
5. Set the WB (from menu or modify any slider).
6. It turns very greenish.
7. If the HDD is connected back, the photo turns OK.

It is my workflow. I keep it auto in camera, shot in raw and change it if necessary through the WB settings in the develop panel

I was able to reproduce a similar issue after removing the raw files and switching back to the Library module. Clearly something is wrong with the Smart Previews. I suggest posting one of your raw file that exhibits the issue in the Develop module to Dropbox or other file sharing site for confirmation.

Hi, Todd.

Thanks for your help. That is exactly what I get. I will upload a raw file (14 bit - uncompressed) later on today.

Whenever the WB is changed, the image turns that color. If you undo (Cmd-Z) or reconnect the HDD, it looks back OK.

Moreover, I have realized that in some files the bug arises just when you change to the develop module. In this case, some greenish squares/rectangles overlap the image, not the complete image (it depends on the image: in some it is a big strip, in other a big square,...). In the same way, whenever the original raw file is reconnected, the issue disappears.

BR, 
Miguel

The 2nd issue sounds like a graphics driver issue (greenishsquares/rectangles overlap the image). In LR go to menu Edit> Preferences> Performance and uncheck 'Use Graphics Processor.' In fact both issues may be due to an incompatible graphics driver. After rebooting my system this morning I can no longer duplicate the issue with the same file I used yesterday. It will be interesting to see if I can duplicate the issue with one of your files.

Hi, Todd.

I will upload an original once I am back in my studio later today (this is why I use to work with smart previews and love this feature...).

Thought it was the GPU too. I tried disabling it, but same result.

Moreover, if you close the program and launch it again, sometimes solves it, but temporarily. Sonner or later you will experience it again.

And it never happens when working with the original. If you have a greenish square, rectangle,... or even the complete photo and you reconnect the external HDD with the original, the issue automatically disappears.

Todd, Sunil,

Please, you may download a couple of samples form de following link: https://www.dropbox.com/sh/44kuc6pfe7mxahv/AAD7rx08e5EDHme_-wMSlD51a?dl=0

I have aso included screen captures (.pnf files) of the issue.

Once dowloaded, please let me know to delete them.

As said, whenever I reconnect the external HDD with the originals, the photo turns OK automatically.

Again, many thanks for your help.

BR,
Miguel

I was able to duplicate the issue with one of the files (DSC3440.ARW). The green tint appears in the Library module, but not the Develop module. It appears you are using a Mac system. What OS X version? I'm on Windows 7 SP1, which may explain the difference in the symptoms.  I had to change the Camera Profile to 'Adobe Standard' and WB setting to 'Daylight' to trigger the green color shift. When I clicked on the Develop Reset and reentered the same settings the green shift would no longer appear. Whatever is causing this issue it's difficult to duplicate at least on Windows 7.

Regardless of these differences the issue appears on both platforms and needs to be investigated by Adobe Engineering.

Hi, Sunil.

I believe a Lr Classic update has been released today. Does it address this issue?

Many thanks,
Miguel

Made some tests today. It has not been solved yet.

With the experience I would say it affects to high ISO and high contrast photos mainly.

Miguel, there is no mention of this issue being fixed in the LR 7.5 Release Notes. I've changed the status of this report to 'Acknowledged' so hopefully it will get some attention.
