P: Imported DNGs not showing B&W Mix

[FeedbackCommunityMember]

[See here for a step-by-step bug recipe: https://feedback.photoshop.com/conversations/lightroom-classic/lightroom-classic-imported-dngs-not-s...]

Hi everyone,

Running the recent Lightroom Classic v10.2 update on my macOS Big Sur 11.2.2.

I imported some DNGs where the Treatment was set to Black & White and the Profile was Adobe Monochrome.

By defult, these setting should trigger the B&W Mix panel to appear, but instead HSL/Color is showing.

Currently, I can fix this by switching the Treatment to Color and then back to Black & White to get the B&W Mix panel to appear with all the sliders shown with the correct settings, but this is tedious.

Thank you,
Chrysta Giffen

"I imported some DNGs where the Treatment was set to Black & White and the Profile was Adobe Monochrome." 

What was the source of the original DNGs? 

Were they edited in another software package prior to import?

I am trying to understand how they were set to Adobe Monochrome prior to import.

Edited by a client using the same version of Lightroom Classic v10.2. Then sent to me and imported into my Lightroom Classic v10.2.

This is for a class where the client shoots in RAW, edits images in LR, then exports and sends to me as DNGs.

Thanks for the help, Rikk!

If your client tries to open the dng do they see the same issue?

* Update* This is happing with files from multiple people. All the same issue.

As per your question: Students will not be about to import the same DNG into Lightroom because it would be a duplicate file.

All students started by importing a RAW file from their camera via "Copy as DNG" in import dialog, then editing the DNG to B&W in Lightroom Classic, by changing the Profile to Adobe Monochrome or one of the other B&W profiles, and developing it with the B&W Mix panel.

Students are then sending me (their instructor) their editing images as exported DNGs.

If the student cannot reimport the file to check it, then can you send a file in for evaluation?

Here's a bug recipe:

1. Select a raw photo.

2. Library > Convert Photo To DNG.

3. Edit the DNG in Develop.

4. Select Treatment: Black & White.

5. Metadata > Save Metadata To File.

6. Remove the DNG from the catalog.

7. Reimport the DNG.

8. Edit the DNG in Develop and observe that the HSL/Color panel is incorrectly displayed rather than B & W:

9. Change Treatment to Color and then Black & White.

10. Observe that the B & W panel is now displayed.

I already had a fix for this as stated in my original post. This is just to alert Adobe of the bug issue:

"Currently, I can fix this by switching the Treatment to Color and then back to Black & White to get the B&W Mix panel to appear with all the sliders shown with the correct settings, but this is tedious."

[johnrellis]

Right -- I posted the bug recipe just to make it easier for Adobe developers to reproduce the problem.

Unfortunately, I cannot due protecting their copyright.

Ahh, I see! Thank you!
