Sky replacement with my own pictures

Hello

I tried to use my own sky pictures for the sky replacement. In general it's working, but the sky looks very pixelated. You might think the resolution of my pictures is not high enough. But this is not the case. No matter if I take pictures with 3500x2300 pixels or 5500x4000 pixels, the inserted sky looks very pixelated. But my sky pictures are looking good in Lightroom. So where is the secret? What are the requirements for your own sky images using it in the sky replacement tool?

Andreas

    Possible color space issue? sRGB vs AdobeRGB? What ever the case, I am not seeing this in my sky replacement tests.

    Je n'ai pas de problèmes avec mes fichiers de ciels .

    Mais je regrette qu'on ne puisse pas les intégrer dans une bibliothéque permanente prise en compte par le logiciel comme les bibli pré installées.

    I tried to use the same sky picture with just 2000 pixel and it looks better.
    But then the question is why a sky picture with a much lower resolution looks better? It should be possible to use pictures also with 5000 pixel.

    I would convert the sky to the same res and dimensions as the photo I am changing.  That way L4 does not have to rescale.

    I use Windows 10, I started a collection of my own skies. I saved them as Tiff files. The ones I have used so far as sky replacement have worked find. I do not process my own sky only export to TIFF. That way I can adjust as part of total photo.

    However, I find the AI Sky Adjust tool provides better results, if there is any sky to recover.

    For some pictures it works if I use a TIFF file for sky replacement, but not for all.
    But I think I find out the problem now. What I find out is the following:

    After changing the sky, the sky in Luminar 4 looks pixelated, as if it was photographed with a high ISO value. However, if you export the image with Luminar 4 as jpeg with the maximum resolution, the exported image will looks better than the displayed image within Luminar. The image looks then OK. Maybe somebody who has the same problem could also try this.
