P: Samsung Expert Raw DNG output shows green/over exposed photo in Lightroom

[Joseph38360771om2u]

It looks like something with Lightroom is incorrectly processing Samsung s23 ultra expert raw photos. They now immediately turn green when opened in Lightroom. This was not the case before. The bottom are photos that were done before and the top are what happens to them now.

Hi. I've got a bunch of DNG images from my phone that appear just fine in the Windows preview pane, or in the Windows photo display "app." But as soon as I try to open them in Camera Raw, they look like garbage. The weird thing is photos from the same phone, from a prior outing, seem to work just fine with Camera Raw, so I'm not sure why images that look "fine" in File Explorer look so completely wrong in Camera Raw. Here's what I mean: In the first photo, the preview looks fine, the Camera Raw preview is all wrong; in the second photo, the preview looks fine, and the Camera Raw preview looks correct. Both images were shot on the same phone: I have no idea why I'm getting these results nor what to do to correct things. Any thoughts? Thank you.

I would begin by checking your Camera Raw default settings. Some settings seem to have been applied to make the image appear differently. Camera Raw cannot ruin your images so you should be able to undo any applied settings and revert to normality.

Thanks for replying. I'll admit I'm not sure what settings to look at: everything looks pretty "default," as far as I'm aware. I'm wondering if it's the photo itself (if I overlooked an update that "wrecked" something in my phone). I tried opening an affected file on a different computer, and it gives me that same, extremely washed-out, extremely green result. I'm including an example file (trying to, at least) in case anyone bored enough sees this and wants a challenge. Thanks for checking things out!

Hmm. This is interesting. I attached the file I pulled from my phone, clicked "Post," and received a message saying the octet stream didn't match the file extension. I don't know what that means, but now I'm wondering just exactly what kind of data are in this file! As mentioned in the OP, opening DNG files in Camera RAW used to "just work:" I'm not sure what all this octet-stream fun stuff is all about. Sigh.

After poking around the Internet a little more, I discovered others had deleted the Expert RAW app from their phones and reinstalled it. That does "fix" future photos, but my originally impacted raw photos remain terrible. My "solution" for now is to just use the JPGs and cry about it. Oh well.

@Balakay612 had this problem as well, and my long exposure photos were ruined 🙃

I clicked around 250 pictures in Expert RAW on recent trip - all default settings. Out of those, first 50 were shot at RAW + JPG and they all look fine in Camera RAW. Then I made the change to shoot only RAW/DNG. I thought that stopped the additional processing that the camera does and allows for a more reactive application. To my horror, all 200 odd DNG files appear washed out in camera raw. I hope I will get a fix soon as the same opens perfectly fine in default Windows Photos application.

@moserbaer, update to the latest Expert Raw version as described here:

https://community.adobe.com/t5/lightroom-ecosystem-cloud-based-discussions/p-samsung-expert-raw-dng-...

That should fix the issue with future DNGs you take.

[Covah31852031n2uw]

There's no fix coming for that issue it seems, Samsung failed and pushed an update that made dng images corrupt for certain systems. There are three things you can do.

1. You can fix future images by following the advice found in this thread.

2. You can recover JPGs from your DNGs, but the full range of image data stored in the dng is corrupt.

3. You can make sure to not buy Samsung in the future and tell your friends the same.

[darek_0755]

Do not buy Samsung is a good idea, if they cannot provide a solution to the broken photos then, there is no purpose in trusting them that other things will work.

Hi. Trouble. The same problem. All files shot with expert raw in Samsung (Samsung's Expert raw program was installed last from the store) Adobe Lightroom in win 10 (and in android) open in green and with an overexposed image. I also noticed that if you uncheck the "save lossless" checkbox, this problem will disappear (do not enable this flag). The only possible way is to save the embedded jpg (FastStone). But the resolution immediately drops there (300 dpi v.s. 96 dpi). They write that jpg XL is inserted inside the DNG container, but this does not make it easier for me. How can I restore my files that are so dear to me now? How do I save files in full resolution?

@Deleted User,  Update to the latest Expert Raw version as described here:

"The only possible way is to save the embedded jpg (FastStone). But the resolution immediately drops there (300 dpi v.s. 96 dpi)."

What matters is the pixel dimensions of the JPEG, not the recorded DPI.  Double check the dimensions -- with other problem Samsung DNGs, my Faststone shows the JPEG dimensions as 5712 x 4284.

Samsung shoots 3000x4000 in jpg

[johnrellis]

"Samsung shoots 3000x4000 in jpg"

By "other problem Samsung DNGs", I was referring to ones taken by the Samsung Galaxy S24 Ultra, which are 5172 x 4284.

That screenshot indicates the JPEG has dimensions 4000 x 3000:

The recorded DPI is just a hint to printing apps about the suggested physical size of a print -- it has no impact on the quality of the image.

When I turn on the function lossless RAW on my samsung galaxy s23 ultra lightroom mobile can't render the details and blows out the whole picture. Please Adobe fix this...
