This is a stitched image that is too large to post on UHH.
Interior pano DNG format, 172MB.

The idea here is to show what we can do using the warp tool offered by PS CC.

The first step is to create guides in order to control when, where and how to warp.
► Creating guides:
 → Place the mouse or pen on a ruler (vertical or horizontal)
 → Press Control (Command) click on the ruler and drag the created guide into position.
 → To edit a guide Ctrl-Click on it and drag.
► Select warp (Menu ► Edit ► Transform ► Warp)
 → The key here is not to try to do everything at the same time, it will not work. In this case I started on top, ended this process then went to the bottom, ended this process and went to the sides, one at the time.


That's it, it is a simple process.

To remove the guide, control click on one, drag it back to the ruler, done.

As usual, you provide needed tutorials and you provide the tutorial well. Good work Rongnongno

Is warp the same as in some editing programs ... "Perspective"?
When I am using the perspective tool, I enlarge the canvas so as to save something of importance at the image edge that would be lost... perhaps saved by doing some clone brushing fill-in of background.

I do not know.
PS CC offers several perspective and warp tools as well as perspective warp!!!
Each has their use and limitations.
They are not to be confused with liquefy...
