Today updated my LR from 13.x to 14.0, looking forward for the improvements, especially
Denoise supports more RAW file formats. (incl HDR and panorama DNG files)
Just tried it on my windows machine (Windows 11, version 23H2)
I did:
HDR Merge of 5 Sony .ARW files into a new HDR-enhanced.dng file : looks good / as expected

Denoise AI of this file results in many (awful) : see partial screenshot (100%)

Am I doing something wrong?
Can give details if needed (computer info, Driver details etc.)
Thanks!

Thank you for sending the sample files. The dynamic range of the scene you've photographed and merged is beyond the ability of the Denoise model for Linear Raws. The team is evaluating future enhancements for this tool, and your images are a nice real-world example.

Thank you Rikk for the instand feedback.
fyi. I've applied the same workflow, this time not on 5 but only the 3 brightest pictures, the result is better but still a mess. (unusable)

Some additional improvements were made in the December Release.

Hello Jeffrey,

This is the link https://we.tl/t-z5zCPh4o2H to the
* 5 original RAW files (Sony .ARW)
* HDR merge (.dng) this is looking correct
* HDR merge with Denoise AI with the awful colors and artifacts.
Thank you for looking into this.

Thanks for catching and reporting this. Can I request the originals that were used to merge to HDR? I have not been able to reproduce this will similar night ARW HDR images.
