New denoise function "Denoise is not currently available with this photo format"

[Jonathan29496921jz23]

Hi, I want to test out the new function on some noisy low light photos I have but am met with the message "Denoise is not currently supported with this photo format"

On the site it says "Denoise is currently supported only for Bayer and X-trans mosaic raw files" My camera is a Cannon EOS Rebel T6, which does use Bayer Mosaic, so shouldn't it be able to utilize this function?

Is there a specific setting on the camera or something when i transfer the files to the computer that is changing it? Any help is appreciated, thanks!

And what format are you camera images in? Are you using anything out of the ordinary, like compressed files?

Note in the New Features - " from Bayer or X-Trans RAW images,"  CR2, CR3, NEF, ARW, etc.

JPGs, TIFs, PSD, and other demozaiced (rendered RGB) files are not compatible, yet! Maybe they will be added in a future release.

I am having the same issue. My files are .CR3. I would think this should work, the message I get reads: "Unsupported Photo:  The selected photo is not supported by this feature."

Thanks for any help. 

[JohanElzenga]

Go into your camera menu and check the settings. CR3 is the general file extension that Canon uses for raw files, so I would not be surprised if they used that extension for M-RAW files as well.

What about with a Nikon? 

[andreiws2]

If you're using compressed RAW it might not work. 

[JohanElzenga]

Are you perhaps using M-RAW? Despite its name, M-RAW is not raw anymore. It's linear RGB and thus incompatible with Denoise.

[UnsatisfiedCustomer987]

Thanks for this info. I had forgotten all about M-RAW (in Canon). You saved me considerable time and frustration!

[Priscila Maboni]

Hi, how are you? Thank you for the info. Do you know if is there any way of "convert" the image after being taken in M-raw to make it compatible with denoise? 

[JohanElzenga]

No, that is not possible. Denoise currently only works with raw files. You cannot convert an RGB file back to raw. That would be like converting a fried egg back to a raw egg again.

[Priscila Maboni]

hahahaah yes, this is known, thank you. I might have not expressed well what I meant. But that's ok. Means that after taken in M-Raw (even if is still Cr3 or DNG) , there is not a way of convert to some extension that could possibible be written by Lr. To me is problematic and the function will never be used... I can't take full Raw (the size of the files are a waste of space for what I do). So I take all M-Raw.

I think you misunderstood my point. Despite its name, M-Raw is not raw. Raw is 'mosaiced', meaning that there is only one color per pixel. That is the only format that Denoise currently supports. M-Raw is not mosaiced, however. It's linear RGB, meaning it has three colors per pixel. And converting RGB to mosaiced is converting fried eggs to raw eggs.

I have the same issue.

I have two PCs and I see that same photo can be edited on one and cannot be edited on another.
Thus I suspect the issue is because of the hardware, not the pictures.

Moreover different camera pictures produce the same issue.

[jamesffclark]

I was gettng the same error message.  I updated my nVidia graphics driver, and now it works.

[Henrik Heigl]

Hi,

that the camera can shoot in that Format does not necessary mean that the photos are actually in this format. I would suggest to check the Format that is setup in the camera, try to use other Options, Update Firmware of the Camera and maybe play around with some other Filetypes on the Computer. Often Export and then Import photos again into Lightroom could fix those issues and cross check in which direction the solution could be. Hope that helps a bit.

[Ian28790607oaic]

I am having the same problem with my CR2 photos from my Canon 5D Mark IV and it is deffinatly shooting RAW.

I edited another photo from the same shoot and Denoise works. Same camera same card same upload time same format.

[duknov007]

same exact camera; same exact problem.. a bug?

same shoot, another image works.. 😑

@Ian28790607oaic  & @duknov007 

Greetings, 

Would you be able to supply two image files from the same shoot where one file will accept Enhance>Denoise and another will not?  That would help us diagnose the issue. 

Note: you cannot attach raw files to this forum. You will need to upload them to Creative Cloud Files, Dropbox or similar.

Thanks for your help.

[Ian28790607oaic]

Not sure why, but today it works.

Maybe it was because I reimported the same pic into another catalog so i could send it to you. Not sure why.

Looking to see when the last update was applied.

[duknov007]

yup I changed nothing; but it worked today.. 🤷🏿‍:female_sign:

[Howard2975903549bd]

i have a feeling it's a matter of memory.  I shut down all the other apps i was running and it worked

[jasonm51946290]

I am having the same issue but my files are dng files from 2018. The origional format was Nikon NEF (D850)

[Michael23406918pkb9]

After testing this against a number of Sony ARW files, both uncompressed RAW and lossless compressed (L), I suspect this error message is showing up at least some of the time for reasons other than an image being in an unsupported format.

I've gotten Denoise to work in Desktop 6.3.1 (OSX 13.3.1, intel) for a number of photos, but only after trying and failing to use it multiple times, making me think the format itself isn't the issue in my case. And whenever I do get an erorr, it seems to correspond with some OSX console logs reporting an error from Lightroom with the message "Error computing NN outputs -1", coming from the com.apple.coreml subsystem. So maybe this an AI runtime error getting disguised as a format issue?

[Valerie29609438c7xe]

I'm getting the same error message but it's only after the latest update. I've tried editing pictures that I had already used it on, but I'm getting the same message.

[Rikk Flohr: Photography]

You cannot apply Denoise to a photo that has already been Denoised. Make sure you are selecting the actual original and not a previous Denoise rendering. 

FYI The update added Denoise so you were not able to do this prior to the update.
