New Denoise AI incompatibility with photo format....Why ?

I've updated to the new LRC and wanted to try out the new Denoise Ai but in every image in my library, it says that it doesn't support the photo format.

I shoot with a nikon D500 on a Sony XQD card in Jpeg......What is so radical about that format that it wouldn't be supported by the new denoise AI ?

[TheDigitalDog]

A new button in the details panel.

If the option is grayed out, the likelihood is, the data you're trying to denoise is not a true raw. Linear DNG or some compressed raw formats are not supported as they are not truly raw data.

Hi I as well have uploaded my raw files and it is not supported. I shoot with Canon 5d Mark IV medium format raw files are not supported . 😞

You uploaded what kind (flavor) of CR3 and where?

[Sean McCormack]

Yes, only full size raw is currently supported. mRAW and sRAW are not. 

[Keith Reeder]

Correct. Canon mRAW files are already demosaiced, and as Adobe has made amply clear, Denoise doesn't work on such files.

[wfroyce]

Denoise AI is not compatible with my Leica M10 Monochrom DNGs or exported versions in TIF or jpeg.  I have to use Topaz Denoise instead.  My Q2 and SL2 DNG files are compatible.  When will this get fixed?

[dj_paige]

Fixed implies that it isn't working as designed, but it is working as designed, so nothing to fix.

Perhaps new features or enhancements are on the way? All anyone can tell you is what Eric Chan wrote: "Denoise is currently supported only for Bayer and X-Trans mosaic raw files, but we’re looking into ways to support other photo formats in the future."

Thanks, good to know

I'm finding some are able to use AI Denoise and other photos are not.  Wondering if I have already done an edit in LRC then it is not supported?...only before an edit is done?  Working with Sony A1 raw and Sony A9II raw.

[markoe52603651]

It works REALLY great with some files (like fr3) but with Ricoh GR3 dng files it processes to no difference (to my eyes)- it is compatible, but changes nothing.

[Sean McCormack]

I can definitely see differences there. What you get depends on the level you set it to in the Enhance dialog. Maybe try a higher setting. 

[markoe52603651]

Maybe. That's 300%. Setting is 25, which is high for iso 2000 at least for my other files. 
The problem is that no matter which setting from 0-100, the result is the same for these Ricoh gr3 files-it changes nothing.

[markoe52603651]

Here is a 200% view of a 3200 file with +0,5 stops plus shadows lifted to 25 to show more noise. Denoise at 100. The un-enchanced file looks better to me. This is only with Ricoh gr3 dng files.

[Sean McCormack]

If you're asking my opinion, there's horrible chroma noise in the original that's definitely improved in the NR version. If you're asking if this is what Denoise should look like at 100, then no, it's absolutely not what the results should. It should be silky smooth. So yes, there's something up. Start a new post, mark it a bug. Reference this for writing the post:

[Sean McCormack]

Nope. Previous editing in Lightroom Classic makes no difference. It's all down to the demosaic. Some of the Sony raw options for smaller files are demosaiced. It has to be the full-sized raw.

It's 2025, 2 years since this thread was started and no other formats are still supported but RAW. 

I really want to try it on a scanned image, but my scanner doesn't save in other formats but JPG, PNG and TIFF. I thought TIFF was a raw format but seem I was wrong and now I have thousands and thousands of TIFF files.

Is there a workaround or a way to trick the app so a TIFF is masked as a RAW? I really want to see the result of Denoise AI on old photographs.

[dj_paige]

Workaround? Yes, other software can AI denoise JPG and TIFF. I don't know which other software has these features, but that's what the internet is for.

[Loredim]

I've seen a lot of tools, mostly online platforms where you upload a photo and get a result. I'm not interested in uploading any personal stuff online or in paying more money for new tools, I want to use my Adobe licence, which was isn't exactly cheap, to do the job it's supposed to do.

[dj_paige]

I am told that Topaz AI denoises JPG photos.

By @Loredim

The reason there isn't a workaround is that (I think) the way they are currently doing Denoise depends on being able to analyze true raw data, that is, data that hasn’t been demosaiced to RGB channels. I think it might have to do with being able to read the values originally recorded at each camera sensor photosite, to create a better model of that sensor’s noise characteristics. That is not possible after the raw data has been converted to channels, because that conversion loses the raw level data.

But TIFF files are post-raw files with channels, so they are already beyond the point where Denoise can analyze them. A scanner can’t produce the same kind of raw file that a digital camera sensor can, because just the fact that you’re scanning film or a print means it’s a generation or two away from the original scene data.

I thought TIFF was a raw format but seem I was wrong and now I have thousands and thousands of TIFF files.

By @Loredim

It can be a little confusing. I think some camera raw files are stored in a form of TIFF, but the common TIFF format many programs can read is not camera raw data.

I am on your side. I have lots of TIFF scans of old photos and would like to reduce the grain. But there’s a problem here. Denoise is specifically designed for digital camera sensor noise. If we have scans of old film photos, we are not talking about that at all. We are seeing film grain, which is a completely different kind of thing altogether. You would need a feature specifically designed (or trained, if AI) to recognize and remove patterns of analog film grain. 

So, if you did manage to find a way to trick Denoise into accepting a TIFF file (or if Denoise was upgraded to accept non-raw files), you would probably find that is not enough to meet your goal, because Denoise is currently trained on digital camera raw sensor noise only. This means, for old film scans, you (and I) don’t just want Denoise to be trained on non-raw formats. You and I also want Denoise to be trained on something it is not currently designed to handle, which is analog film grain.

[DdeGannes]

@Conrad_C , I agree with this post from Canrad.

Simply put LrC is designed as an application to work with RAW files from Digital Cameras and this is it's core function. It is nondestructive processer and dose not alter the original imported images all edit info is stored in the Catalog file.

Just my thoughts.

[ExUSA]

Yes, AI Denoise only works on RAW images out of a camera. Scanner software can't create RAW files as it uses different technology. You can use the older denoise features in Lightroom or try a different app (there are numerous ones on the market.)
