Artifacts at Edges of Galaxy S7 RAW DNG Files in Ps, Lr
Classic and Lr Products Affected: Photoshop CC 2019 ACR, Lightroom CC Classic2019, Lightroom CC 2019, Lightroom CC for Mobile (Android)

Description: DNG RAW Photos from the Samsung Galaxy S7exhibit artifacts at one edge after importation or opening in the affectedproducts. The artifact may be solid black or a random set of colors. It alwaysoccurs in a straight strip along one edge of the images. In Lightroom CCClassic it occurs in both Library and Develop modules and sometimes shows up inthe thumbnails on the filmstrip. Sometimes the artifact will not appear inLibrary but will appear there after going to Develop and back.

Associated Files:

Two affected DNG RAW files from the Galaxy S7, along with ascreen shot showing a typical artifact marked with an arrow are at: https://www.dropbox.com/sh/73bvkcoxwlmqy7u/AADr1DOYXYzMzA-ad6_FPxeNa?dl=0

Reproduction:

1. Take a photo in RAW with the Samsung Galaxy S7.

2. Copy the photo to a computer via USB.

3. Import to or open the photo in one of the affectedproducts. Observe that the artifact strip appears at one edge of the photo.

Alternately

1. Take a photo in RAW on Galaxy S7,

2. Import the RAW photo into Lightroom CC Mobile

3. Observe the artifact at one edge of the image. Note: theartifact is thin, so it may be hard to see. The artifact isn’t always seen onmobile. If it doesn’t appear, try going back to the library view and openingthe photo once again.

Workaround within the Products: None. The only recourse isto either crop out the artifact strip or to convert the DNG to TIFF andreimport the TIFF to the Adobe product. Cropping out the artifact strip is nota trusted workaround, because the artifact strip might reappear in the future,despite the crop.

What Has Been Tried/Previous History:

1. DNG photos from two different Samsung Galaxy s7smartphones have been imported or opened, with the same result.

2. About 15 photos have been opened. All exhibit the same result.

3. The DNG photos open normally within Skylum Luminar,Powerlink Media Player for Dell, Android Gallery on Samsung S7 and GooglePhotos without exhibiting these artifacts or any other artifacts.

4. The artifacts appear in Lightroom CC Classis 2019 on bothone desktop and one laptop computer.

5. I cannot say for sure, but I do not believe this problemoccurred prior to Lightroom CC Classic 2019, because I would have seen theartifacts while editing these images in Develop. I don’t remember seeing themon the prior version.

LO again,
Forced to upgrade to version 8.0 (use the Cards module), and also have to do a little work on the S7, with the understanding that it is not possible to make two versions live together via "Adobe Creative Cloud", I tried an ugly hack (works on Windows 10):
Quit LR. Rename folder "Adobe Lightroom Classic CC" to "Adobe Lightroom Classic CC Last". Install version 7.5. Rename each folder "as it should" allows to launch choice of version 8.0 or version 7.5.
I then repeated the operation in the other direction so that the last version is "the official one".

OK, this may be worth taking note of...

"Corrupted" DNG files (Sam Galaxy S9+) display correctly when opened in Adobe DNG Profile Editor.

And, no, it's not the embedded preview. I can zoom in to 1600% and still make out rough details.

So, what's the difference between the way in which the DNG files are read by Profile Editor versus Lightroom?

It seems likely that the source of the problem can be found somewhere in that difference.

At least temporarily I'm editing these files in other photo editors that do render them correctly. I can then export the result in .tif to Lr if necessary.

Wanted to follow up with the Adobe employees following this issue - has there been any status update as to timing for a fix? Based on investigation of the problem, in the meantime, is there any workaround available to allow Samsung s7/8/9 DNG files to be correctly edited in Lr?

I don't think the problem is in Samsung's camera because the problem came after the ACR upgrade to version 11. Before that I never had such artifacts.

But you're right - pictures made with LR app (or FV-5 app) have no such problems (at least at first glance)

I've just noticed that the DNG files produced with Pro mode on the Samsung Note 9 have started getting a 'fringe' on one edge when imported to LR.

This may well be a Samsung problem but thought I'd raise it here first.

The odd thing is that when viewing the DNG files in the Note9's own Gallery there is no fringing. - it can only be seen when the photos are imported into Lightroom.

However, DNG pictures taken with the LR app (or Moment app) do not show fringing in either the Note 9 Gallery, or in LR!

Examples here: https://adobe.ly/2FTgwQq

Advice appreciated. Has anyone else noticed this?

Thanks,
Richard

I can confirm I have been seeing the same thing as well with ACR 11 and both Photoshop/Lightroom CC 2019. Files tested were raw DNG's from Samsung Galaxy S8. Artifacts only appear on long axis of the image. Files previously processed by ACR 10 and Photoshop/Lightroom CC 2018 that are opened in the new release now show the problem when before there were no artifacts. This was tested on various images from earlier in the year (prior to 2019's release). Tested S8 DNG images on a NAS, on external drive, and stored locally and no change in behavior; all exhibit same artifact.

Only change when disabling graphics card is the row of pixels becomes a black row instead of exhibiting various colors. Image data is still missing from the edge of the file, just is filled in differently with graphics card enabled or disabled.

As another test step, opened up the images (old and new) on laptop (still running ACR 10.5/CC 2018) after they were touched by the 2019 release and everything still opens fine; no edge artifacts are observed in this release.

I'm also having the same problem with Galaxy S8+ DNG files. I have a detailed posting about this problem on Adobe Forums and someone directed me to here and asked to add my details.

Comparison of in-camera JPG on left, with raw DNG file on right opened in LR. Note the bottom row of corrupt pixels in pink/black/grey patterns.

And this is what the DNG File looks like when exported to JPG (100% crop):

When the same DNG file is opened in RawTherapee there is no corruption:
