    Yes, I do have the same problem and i can reproduce it with any portrait picture. Those dead (red green blue) pixels appear almost every time when applying the portrait enhancer tool. At the moment it is not possible to work with this version. I tried it with my imac and macbook. I even tried it without graphic card rendering and also tried it as plugin in apple´s photos. Always the same failures.

    I have the same problem. It does not happen every time but randomly... Mainly in the dark shadows or blacks. Color pixels appear like clusters, not all together but scattered: red, green and blue.

    Has there been any update on this? I just downloaded a trial and I'm having the same issues. I'll email support as mentioned above, but I'm curious to know if anyone has figured it out.

    If I see them, I can use the mask feature to focus on the face, and then the pixels disappear, but that won't really help if I'm trying to bulk update pictures.

    Hi Eric,

    Regrettably, this issue is still a work in progress. Our team is doing their best to get this fixed ASAP, but at this time there's still no precise ETA on this matter.

    There is too much of problem with AI portrait enhancer.

    - AI Skin enhancer create pixel noise on low key images. Mostly at the darket part with random white and color pixels.
    - eye enhancer and face slimmer render the image preview (at fit screen mode) unsharp

    :(

    Having the same issues of dead pixels in the shadows.  Very frustrating having to clean up an image that was already cleaned up to begin with.

    I have experienced this problem as well in both Luminar 4 and now in Luminar AI. There is significant noise in the shadowy areas. I do my RAW processing in Capture One and then edit a JPG in Luminar. Editing the JPG in Luminar produces noise, while editing that same JPG in Capture One does not, even when boosting shadows or increasing the exposure to an extreme level.

    Oh no. I was hopping for Lumninar AI to work. This will make me wait for a fix, before I buy. I love the Luminar workflow, but it is not useable this way. Sad. Please support, fix this problem :-D

    I noticed that, if I don't clip blacks when pre-editing in Lightroom, I don't get those artefacts in Luminar

    I upgraded to Luminar AI and the issue is there, specially in the dark areas: multiples dots or pixels in raw colors like blue, green or red, in scattered clusters. This is not new and I did hope the upgrade appeared with the issue already fixed but it looks well will have to wait more. I'd appreciate, if somebody knows, could tell us if this issue is being addressed by Skylum teams.

    Thanks in advance,

    Ricardo León

    @Angela Andrieux This issue exists in Luminar AI. I've sent a screenshot to support. I'm not sure if it's explicitly stated in this thread, but the dead pixels are visible in export from Luminar AI.

    Unfortunately, I bought the software without trying it first. This is incredibly disappointing. I can't believe I never saw this issue mentioned in any professional reviews of the software. 

    iMac 19,1

    OSX 11.1
    Latest versions of Photoshop and Lightroom Classic

    Same problem here with Luminar AI.  Really frustrating to do edits in Lightroom, export to Luminar for more edits, export back to Lightroom continuing my work flow and somewhere down the line discovering the dead/hot pixels in dark areas and then have to start all over again.  I really want Luminar to work because it genuinely speeds up my workflow.  Hopefully the next update fixes this issue.  Mac Mini OSX 11.1, latest version of Lightroom CC

    This is the first time I noticed "dead pixels" in Luminar 4.3.2 (MacOS 10.12.6 Sierra)

    These are of green color and appear in a small dark area (forrest) of a landscape photography - therefore NO "AI portrait enhancer" was in use, but of course some other AI tools. 

    As Member Michael Velasquez already stated for Luminar AI, this problem of "dead pixels" in my case occur in export files, too. I even can't find any "dead pixels" while editing that (original) picture, but ONLY in export files (in this case export as PSD).

    Most annoying:
    I never knew about this issue before. A couple of days ago I sent the mentioned photography to a print shop and cound't believe what I got delivered today. "Just" 100 Bucks wasted for a crap! Just because I didn't check the exported file - for the first time ever, I did not check an export file for the first time and got punished immediately for my dumb trust into Luminar 4.

    By the way:
    I already bought Luminar AI when got the opportunity to pre-order. Because I have to upgrade my OS to High Sierra first, I am not using this version at the moment. Until this bug isn't fixed, I see no sense to upgrade my OS and install another buggy program. Maybe just some other "wasted bucks" if the bug will not be fixed...

    I really hope, this bug will be fixed soon. But by now, I have to look up for another gift for my girlfriend's birthday. Thanks alot to Skylum and kind regards.

    Well Helga, the only so-called "AI tools" I've been using in this particular image are the following:

    On the original picture I used
    AI Accent & AI Sky Enhancer (with a gradient mask)
    AI Structure and Boost with a copy of the mask mentioned above

    Further
    Color with the same mask
    Detail Enhancer with a Luminosity mask
    Denoise with the same Luminosity mask, but inverted
    Landscape enhancer (w/o any mask)
    and Adjustable Gradient and Dodge & Burn

    Next I made use of the Erase tool and Crop & Rotate. This created a new layer.
    On this new layer I made use of the following AI tools:

    AI Accent & AI Structure (with a gradient mask)
    AI Structure w/o any Boost but with a copy of the mask mentioned above

    Of course there were also some other tools in use with this layer (e.g. in Light, Color, Vignette as well as Fog and Adjustable Gradient) 

    In the view of Luminar's main window, no "dead pixels" appear. Neither when cropping to 100%. But those pixels appear in the exported PSD and JPG files. No need to crop to 100% - they are visible with ease even at 20% or below.

    No big problem for me to send the requested files. But which of them do you like to receive? JPG, PSD or what? I can also provide screenshots when Luminar is running with that image after the final step (just before exporting) - even the 100% crop of the area affected in the later export files. Just specify a bit more what you like to receive.

     

    EDIT:
    Now the story starts to become weird!
    To make the statements above in english language, I turned Luminar from German to English and restarted the program. Right after sending my comments, I switched over to the fullscreen preview to make the screenshots and NOW I discovered the "dead pixels" for the first time on the edited original image! Unfortunately, after turning Luminar back to German language, the "dead pixels" remain on the picture. Therefore it is impossible now, to provide a screenshot without that pixels...

    BUT:
    I switched all the filters used on the upper layer off and on - one by one, just trying to find the filter responsible for these "dead pixels". And finally I found it!

    In my particular case, the filter ADJUSTABLE GRADIENT is responsible for the green colored "dead pixel".

    Well, I cannot say whether or not there is any other filter responsible in combination with Adjustable Gradient on the upper layer. But I hope, this information helps to find a solution for that problem.

    Still interested into the pictures / screenshots? Just let me know.

    Also experiencing the issue - exclusively with the skin enhancement tool and exclusively in low key photos.  Completely and reliably reproducible.  Y'all got yourselves a bug.

    Hi Joshua,

    I'm sorry to hear about the issue you have faced. Could you please reach out to our team at https://skylum.com/support and send a couple of screenshots illustrating the issue? Thanks!

    Hey Skylum support - I'm baffled as to why you keep asking us to send screenshots etc. This issue has been ongoing for a year. I get the impression that rather than fix it, you just ask for images, and hope we'll forget about it. Surely one year is long enough to fix this bug? Why is it taking so long?

    Hi Joshua,

    I can confirm that those are exact the same problems that I have since I bought the software over one year ago. I can reproduce them every time. I think it appears when dark areas are clipped.

    Hi Everyone,

    I had the same issue and updated to the recently released version and this issue is gone. Which is good, because it was unusable and I was about to ask for my money back. I still might since it took a year to solve this problem.

    For those following along... skylum acknowledged the problem and said that the best fix was to buy luminar AI at a discounted rate.
