Missing Camera Profile after Importing DNG from Topaz DeNoise AI

[davidr98816850]

Hello all,

 I am using Lightroom Classic and Topaz DeNoise AI.

My work flow is Import image to Lightroom Classic > Find file in Finder > Open RAW immage in DeNoise AI > Export from DeNoise as DNG to same folder as input > Sync folder in Lighrroom.

I do this workflow as exporting an image from Lightroom, as TIFF, to DeNoise (as Plug In) returns an image that has less detail than my work flow.

The problem is that the returned DNG file has a yellowish tint to it and I can't apply the same camera profile that I used on the initial imported RAW file. The only available profiless are extremely basic profiles and attempting to import a camera RAW profile only errors with a message that is has already been imported.

Why is Lightroom not giving me the camera profiles on the DNG file and how can I fix this yellow tint issue? The DNG file shows all the camera information, just like the RAW file.

Thanks in advance for the help!

Import image to Lightroom Classic > Find file in Finder > Open RAW immage in DeNoise AI > Export from DeNoise as DNG to same folder as input > Sync folder in Lighrroom.

That may be your problem, try the normal workflow:

• Import into LrC
• Accomplish any desired develop edits, any library (metadata edits) in LrC. As to those Develop module edits, perhaps the Profile, and the WB as a minimum. Might want to look at: https://www.youtube.com/watch?v=CaNsK7MAQbc
• In LrC accomplish an Edit in (Topaz DeNoise)
• Topaz should come up, accomplish your edits, close.

I do this workflow as exporting an image from Lightroom, as TIFF, to DeNoise (as Plug In) returns an image that has less detail than my work flow.

Ok, that needs to be resolved.

In your External Editing Preferences (preset)For Topaz DeNoise, what do you have set up?

Why is Lightroom not giving me the camera profiles on the DNG file and how can I fix this yellow tint issue? The DNG file shows all the camera information, just like the RAW file.

As for issue in camera profile, something in the back of my head about metadata going missing, but I cannot prove. In Topaz DeNoise, the model selected, is that RAW?

As for yellow tint, probably a WB issue. 

I am sure another member will come by and correct my missing info.

and I can't apply the same camera profile that I used on the initial imported RAW file.

Is that an in camera profile or a develop module profile, perhaps a camera matching profile?

GoldingD,

Thank you for all the information. I checked all the links you gave me and everything is working, or setup, per those links. The issue I have is that DeNoise renders a more detailed image when you use it stand along by having it open and process the RAW (CR3) file than it does when used as a Plug-in from Lightroom, which exports the file as a TIFF. Using it as a Plug-in definatly solves the color issue, but I don't get as detailed an image.

If you look closely at the two images below, you can see that the first one has less sharp detail as the first one. You can see it in the fur to the left of the eye most clearly.

This first image is the DeNoise exported picture when DeNoise is used as a Plug-in in Lightroom.

This is the image DeNoise exported when DeNoise was used as stand along and opened, and processed, the RAW file using it's RAW noise profile.

In Topaz DeNoise, in it's preferences, some settings. 

Apply RAW Color Corrections, on/off. Maybe off if coming from LrC?

Oh, and in Topaz DeNoise, is RAW the model selected?

In Google, search on

Topaz only lets you use the RAW settings on RAW, CR3 in my case, files. None of that works when it gets a file from Lightroom Plug-in export (TIFF).

I may be wrong, but I suspect-

A DNG from Topaz DeNoise AI is really only a TIFF image file in a DNG file 'wrapper'

As a result any Profile for a 'true raw' image will not work with the DNG/TIF.

[davidr98816850]

I am concered that you are correct. As the exported image from a RAW file is more detailed than the image from a TIFF file, I really want to use DeNoise on the RAW file and then process the exported DNG file in Lightroom. 

Is there any way to take the camera profile and make one that I can use on the DNG?

[Rob_Cullen]

Apply your Camera Profile to the raw file in LrC before you send it to DeNoise.

"then process the exported DNG file in Lightroom. "- well this is not a 'raw' anymore- it is a TIF (RGB) file 'called a DNG'.

(DNG files are not always exclusively raw data!)

(I am getting a little out of my league with this topic- maybe other gurus will chime in with some technical details. 🙂   )

[davidr98816850]

Thanks Rob_Cullen,

 I am trying to get away from exporting the photo from Lightroom into DeNoise as the resulting image, returned to Lightroom after noise reduction, is not as sharp as opening the RAW file directly by DeNoise, which is one of the new features of it after a recent update. 

 I think the resolution to my issue is in creating a profile for the DNG file that I can apply after I open it in Lightroom. I don't know, however, how to make one that processes the photo the same way the one does on the original RAW file.

At David r, I am on a few days vacation and do not have access to my Computer at the moment to test. Try the following workflow to see if it works for you, use LrC to apply the profile you wish and then use the edit in PS option to send the raw image data to PS, the data should be in memory in PS until you save when a tiff or PSD would be created. Before saving use the filter in PS to send to Topaz DeNoise AI, you can check the resulting tiff t see how it compares with the process directly through DeNoise.

Some thoughts that occurred to me last night.

Workflow LrC to Topaz DeNoise as opposed to straight into DeNoise. Issue is thee TIFF that gets created, the TIFF that you cannot use the RAW model in DeNoise, hence a lesser result. So Going into DeNoise directly is the better option than LrC Edit in.

Topaz created DNG. Is their an update to the app? I ask because a on-line video  (that I cannot share in this community, doing so errors) shows saving the DNG in DeNoise, then bringing into LrC does provide the profiles normally available in a RAW.

A possibility, in LrC, accomplish the minimal, apply profile, correct WB, undo the LrC default sharpening, add your metadata (Title, Caption, CopyRight, etc). THEN convert that to a DNG. Open that DNG in DeNoise, when saved, does DeNoise honor th full spec DNG? Or does it override upon save with the lesser than full spec DNG (as seen in lack of profiles in LrC).

I see I need to go and upgrade my Topaz to AI, etc, Not normally a Topaz user....

Update/

Installed DeNoise, worked with it, in LrC created (exported) DNG file from RAF, in DeNoise, ran that, tried different preference and save settings. No matter what, when brought back into LrC, and in Develop, I get Profile missing. So, not a true DNG???

Not at home at the moment but will check on my desktop when I return on Friday. I tried a couple of videos one that shows a procedure from the develop module to drag the raw file from the filmstrip to DeNoise AI on the desktop. Use DeNoise returned DNG to folder then synchronise the folder to import. Did not work no Adobe profiles are available only user or other third party profiles available.

[DdeGannes]

Another thought, when the DNG is created in LrC make sure metadata is savad to the file before draging it into DeNoiseAI. Will test friday.

[davidr98816850]

GoldingD,

 You are correct. The DeNoise exported DNG is not the same as the DNG that Lightroom would create from the RAW photo.

The is from the latest email I got from Topaz:

"The best workaround I have other than sending the TIFF to DeNoise AI is to use the Photoshop plugin as that sends only the pixel data to DeNoise AI and does not require a camera profile at all.

If you are able to copy and paste the original metadata to the DNG that DeNoise AI outputs, you would be able to use the camera profile.

The exif reader that we use in DeNoise AI is unfortunately very deeply embedded and difficult to replace. It is missing the metadata tags that are required for camera profiles and currently has no easy solution aside from the TIFF and plugin workflows I've shared."

So, do you know how to copy the Metadata that he is refering to from the original RAW to the DeNoise exported DNG? I think that would solve everything.

I have tested this extensively and the dng output by denoise is just a tiff in a dng wrapper. You probably don't want to use it and are better off exporting as tiff with zip compression from denoise for compatibility and for saving a lot of disk space. If you want to do this, the simplest way is to right click in Lightroom Classic and do a show original and drag that onto denoise. Then do the raw denoise and save as tiff. Then simply synchronize the folder in Lightroom Classic which will import the tiff. 

I have not seen eny major advantage of doing this by the way. The raw denoise seems to be much more noise sensitive and give unpredictable results if the originals are very noisy. Also, i like not having to completely redo the image when it comes back into Lightroom as the raw converter in topaz behaves completely different from the one in Lightroom.
