Thanks for the thread. Good education. Especially helpful was the side-by-sides from Greyfox. It highlights the need to have appropriate shadowing in the subject area for the sky being inserted. The result was very good but I got the "feeling" that something was off. Be careful when fooling with Mother Nature.

ACDSee have a quite small allowance for images uploaded to the forum, they don't actually want users to upload high res images.
In most cases relatively low res screen shots are adequate for forum subjects. Where it is necessary to pass on high res images, use a file transfer service like Dropbox or the free WeTransfer service, and post a link in the forum to the download.
In regards to Luminar 4, if you do use it be aware that it's support of metadata is not good, particularly IPTC and XMP, so if it is used freestanding you might find the saved version no longer has some of the metadata. You can avoid that by using it as a plug in from ACDSee's edit mode as I do, but there were some issues reported getting that to work.
Good to know we can use L4 as a plugin to ACDSee.

Hi Regor250!
Thank you very much for these great instructions. I'll try that in a moment.
All the best and stay healthy!

Still, I'm surprised at how well the ACDSee can do. How did you do this? I would be very happy to receive an answer. Thanks in advance.
Sorry for the google translation

One thing that happened when editing this image, I lost the ability to see selection overlay. I could still make a selection, but the overlay wasn't visible. There's an obvious bug, but I am not sure of the sequence of edit I need to do to replicate it. I'll have to work on that. Sometimes saving and closing the image restored the selection overly for a brief moment. I could still save selections (that I couldn't see) to the selection basket, and opening the overly option window showed the presence of the selection, but it wasn't visible in the edit preview window.

I've downloaded and installed Luminar to see how well it handles the sky replacement. I've also decided to start with the original undeveloped raw version instead of the previous processed version. Here is a comparison of the three.
I'm getting better results with Luminar with just a few click. It does a better job blending the two images and with no color cast. Still, I have no plans on using Luminar as my main raw processor. I like how ACDSee features better. I will probably use Luminar in cases like this.

I could only get a low res 300 x 449 image from the forum post, so did an initial enlargement in Topaz Gigapixel AI, then ran L4 as a plug in from ACDSee.

As Alec mentioned in the video, you can download sky images from free on line sources like Unsplash.
I have ones I have downloaded, sky packs I purchased some time ago (but rarely used because they tend to be too dramatic). Mostly though I use ones I have taken myself.
I try to take the images from places where there is a horizon, but with minimum protrusions of objects into the horizon (so taken from a hill or high point, or from a beach). I post crop the bottom of the images at or close to the horizon (so the bottom edge is effectively the horizon point). Knowing where the horizon was helps when positioning the sky on the image.
If you take your own sky images, you can choose ones where the light is from the left, from the right, or evenly spread. Morning shots with the sun rising, evening towards sunset, lots of clouds, relatively clear sky's etc. I would avoid using "spectacular sky shots" at least in the beginning, because there will be few images where they will look real. Remember that the main subject in photos where sky changes are considered would rarely be the sky itself.
Other than shots taken for a specific purpose, like real estate sales photos, or where for artistic reasons one wants to change the tone of an image, most sky changes are probably only considered for images where the sky, or parts of it are blown, but the rest of the image is worth keeping. For realistic results with that type of image, the replacement sky would be expected to be relatively bright and clear.
This is not something I'll do often, but it's good to know it can be done within ACDSee without having to go to an external editor.
I'm not sure how to post the images here that will allow resizing. Sorry about that.
