Hello, Habrachelovek!
In this short article I want to share a useful feature from Photoshop.
May the design gurus forgive me if this seems obvious.
Nevertheless, I think, for beginners and “average”, which I am, the utility will seem very useful.
An accident
I discovered this useful feature for me completely by accident.
It took me some time to create a blurred pattern, I found a picture.
')

At first glance, nothing special, the picture is like a picture.
But upon closer inspection, one can see the lack of photography - an easy perspective.
Insight
I began to choose a dammed area.

But then this very "light perspective" manifested itself.
The picture shows a discrepancy in points.

No “rotations” of the Crop zone helped. The points did not converge.
And here is the illumination! There is also a useful feature Perspective Crop!

All the points we expose ourselves.

In the end, after some manipulations with brightness and offset, a nearly finished tiled picture is obtained.
(which would not hurt a couple more manipulations with brightness).

Now you can safely photograph the wallpaper on the wall next to you!
UPD: fixed, removed the version of Photoshop and the name of the post.
