Background exchange

[psphufi]

Hello, I am trying to exchange this much too bright sky with an image that shows a pleasant sky.

When I use Artificial Intelligence to replace the background, the entire image turns red, there is no selection and I cannot use any brush to mark the outlines.

With the magic stick I can't mark exactly the areas I want to replace either.

How can I use the image "Himmel" to replace the grey background of the building?

Furthermore: It is surely not possible to change this "curved" panorama photo into a flat photo?

Many greetings
Norbert

The Background Replacer is for people only.

Others will be able to offer better suggestions but for this example I had three layers.

1) Sky layer
2) House Layer (with Blend ranges turned on, removing solid whites from the layer)
3) A second House Layer with a mask applied specifically targeting the gables.

For the third layer I used the magic wand tool, set to a low tolerance (3 or 4), the "contiguous" box checked (this limits it to the sky), with a feather of 2 set to "Inside". Then I did Layers -> New Mask Layer -> Hide Selection. And with a black paint brush I cleaned up the edges a little around the tree and edges of the building. If you there is still too much jaggedness around the gables of the house you can select the sky again (this time on the mask layer) and expand the selection by 1 or 2 pixels to help clean it up. Then fill the selection with black

To add to LeviFiction's solution (before to add the sky):

- Add a 100 pixels white border.
- Apply the Adjust/Barrel Distortion Correction at 100%.
- Use the Perspective Correction Tool:

- Finish with the Mesh Warp Tool:
