I've included the results from the Photoshop and Luminar 4 sky replacement tools for comparison. Both tools have pros/cons. Photoshop errors on the side of not overlaying sky on the main feature and Luminar 4 errors on the side of overlaying main features. In cases like this it is probably worth the effort to resort to the tried and true method of sky replacement, i.e.: mask the main feature(s) and overlay them on the sky of your choice. Of course you could also just wait to shoot the picture when the sky is just the way you want it...

Enjoy!

I do not replace skies, but the one you try to show here is pushing the software to a limit beyond the AI technology. It is like to extract the face of a girl with her hair blowing with the wind and expect that every single hair will be recovered without any human action. I think sky replacement can be done with a new one but taken into account tonal and color according with the image.

Looks too phony to me.

"Sky replacement does have its place if the job requires it."

I agree. Many times, like Mr. Shapiro just mentioned, we are photographing a subject or landscape but we do not have the right sky for the image. It has happened to all of us. Under those circumstances sky replacement is a valuable tool IF done right. Nobody here needs to do sky replacement on every image we shoot but having such a tool when we are in need certainly can save an image.

Like others I prefer the original. I use Affinity Photo when I need sky replacement, it is not the best editor for that but I do not do sky replacement often.

The second one is so bizzarro it might make a good album cover for a group named "Blazing Ice" or "Frigid Fire"...

Obviously, both are bad!!!

Try ON1 Sky Replacement. With no tweaks, and just one click, it did an excellent job, far surpassing both examples here presented! If you wish, many further modifications are available, but this needed no modification.

The original is fine and the best. All I would do to it is lighten it a bit and increase the contrast. There is no real background but empty overcast sky as there should be during these weather conditions.

I work with Elements and they have an automated tool but it has shortfalls as well. Using the "refined edge tool" takes time and your tree could give you a migraine Tim Grey has some great videos on how to use the refined edge tool. Google should find it or Youtube. It fine tunes your layer mast. I shoot candids of our grandchildren and use it to change my backgrounds.

This worked ok but it took quite a bit of time. Enlarge the images to review the edges. I had to open some eyes as well, also automated in Elements. It becomes easier with practice. The marketing hype makes it seem so easy but complex images take time to clean it up.

Interesting results. The PS version didn't turn out very well.

I like the original image. Others are cheesy in my opinion.

This is the original image. I brought it into ACR, decreased the highlights, increased the haze and the shadows.
There was a bit of a vignette at the top corners, I removed them.
