Introducing blue colors into the raw file

[thechaddtm (Chadd Dum)]

I have a dark image and wanted to remove a few noise but I’m getting this kind of image after loading it to lightroom

Steps to reproduce issue:

1. Step 1: loaded the raw (topaz photo ai)
2. Step 2: used auto, and used a custom setting (normal denoise)
3. Step 3: loaded to adobe lightroom (its showing these odd blue colors)

@thechaddtm Thanks for uploading that.

I suspect there might be a GPU conflict here.

hi @tim.he i just sent you a message.

Can you post it in this thread as well? I can send you a link to try and update the drivers.

It looks like this is happening in the blacks for the image. Does this happen on other images that have very underexposed sections or only on this image?

Hi @Lingyu ,

I just sent you a message about my updated dx diag file. and i have updated my topaz photo ai too. i also have other files that had those blue lines, again even after the update.

this is another batch of files i just took recently. i used strong denoise and strong sharpen and cropped.

now it has some weird boxes in it.

I’m starting to get hopeless on this tool. i have not encountered these issues using Adobe Lightroom AI denoise.

Please download and run the below installer which is the latest NVIDIA Studio driver. When installing, select Custom Installation > Clean Install. Then reboot your computer after the driver installs.

The two artifacts here (blue spots, grid) are both fixed in the new Remove Noise - Raw models that will be releasing in v2.0 in two weeks. I can check the file in the current beta to see if there are issues happening if you would like. Please send the original Raw file.

You can securely submit your image(s) to my Dropbox using the link below. Please be sure to send me a note to let me know you sent something.

I just finished updating my driver and restart my laptop

now there are 2 new issues

1. when using strong denoise, that’s where the blue colors shows up in underexposed area and its introducing boxes
   

   

2. normal settings and saved new DNG images have no blue color nor boxes BUT its introducing yellow colors to those overexposed areas.

We are releasing a new Remove Noise - Raw Strong model next week so the first issue should be resolved.

The highlight shifting color is a known issue. I am hoping to get a developer working on it very soon.
