LIghtroom's AI denoise is terrible for my drone's DNG files

[nikoskostan]

So I have Canon and Nikon cameras and AI denoise works fine on their RAW files but I also have the DJI AIR 3 drone that when I try to use AI denoise on it's DNG files it doesn't denoise at all, instead it just sharpens the existed noise.

Is there hope?

Can you provide more information? What ISO are the Air 3 images taken at. How is the exposure. Are the images from dark or dusk condition? 

I tried Denoise AI on some DJI Phanton 3 Pro DNG images. Those images had some pretty serious noise in the deep shadows that Denoise AI handled very well.  Not the same as yours of course.

I suggest you post samples here in a reply. Click on the little box with the mountains in the tool bar above the text area to imbed an image in your post.

Better yet, upload a sample DNG to Dropbox, Google Drive, or similar and post the sharing link here.

i have the same problem... its really horrible...
my photos after denoise looks worse than before... (dji mini 4 pro -iso100).
any solutions?

"i have the same problem... its really horrible... my photos after denoise looks worse than before... (dji mini 4 pro -iso100)."

Upload a couple original photos (not screenshots) to Dropbox, Google Drive, or similar and post the sharing link here. Without examples, Adobe is less likely to take any action.

I dont have a raw files what i can share to public (i mean raw files)... 
doesnt matter - after denoise photos looks worse than before... its not ok
this is fast samples... after denoise i see a lot of  "blurry places" etc. 
my friend sended to me raws (dng) from dji mini 2 and denoise works really super nice

Without sample files, Adobe is unlikely to pay much attention.

@amokphoto These images look way too dark and flat. Underexposed by quite a bit. The underexpsure is almost certainly the cause of the noise. Properly exposed images will have less noise, even at higher ISOs. 

Is the drone camera set to a minus exposure compensation by any chance?

Ok, but we talk about denoise, not about dark images. 
I have a problem with denoise - curtain. 
This crops are from all photo and this is problem when i need correct shadows to plus. 
I cant go with exposure +, becouse im shooting sunrise etc and after that picture is totally white - now you know where is a problem?

The problem is :
Denoise on the DNG files from dji mini 3/4 do not work good (its a lot of blurry places and looks totally sh^%) - this is a main problem
THEN, I need solution to repair this on my own (buy TOPAZ, dxo and resignation from Adobe), or adobe need to update the plugin (denoise AI) becouse Im not only one person with this problem... 
Its really easy to solution in my opinion, on my canon R and R6 mk2 denoise works perfectly, and I want to use the denoise on the DNG Raw files.

Hello,

One issue with drone cameras is that the sensor size is fairly small. In your case, the drone DJI mini 4 is small 1/1.3 inch. Despite what it might say on the box, the quality cannot compete with a larger sensor e.g. a DSLR

The drone sensor is similar to a smartphone camera. The sensor is not good in low light. Noise will appear. However, when viewing small it is not so noticeable, but when you enlarge you can see the noise - as in your case.

It is not the fault of Adobe's AI Denoise, even though other programmes may seem to do better.

This is a problem with smaller sensors. The larger sensor sizes in DSLRs allow for better image quality, more detail, and better low-light performance.

That's because the shadows are underexposed, increasing the noise when you "plus" them.

"I cant go with exposure +, becouse im shooting sunrise etc and after that picture is totally white - now you know where is a problem?" In this situation, the easy solution is to do multiple exposures to create an HDR final image. You can do it manually by controlling the Exposure Compensation on the drone (multiple shots of the same subject) if the drone does not have an HDR mode. My old DJI Phantom 3 pro does not have an HDR mode, so I do it manually. In a sunrise situation with the sun in the frame, you may have to do +3 and -3 stops of exposure compensation or more. I'm sure the drone you use does not have the dynamic range that the Canons do.
