How does PS integrate the picture into the background Let's have a look.
Method 1
Open two pictures in ps, and put one picture on the other with the selection tool
Put it in the right place
On the layer panel, select the layer you want to blend into the picture, and click the mask button to create the mask layer.
Then set the foreground color to black and the background color to white
Use the gradient tool, select the mirror gradient, and pull out the gradient. Sometimes the picture is not exactly square, and some edges are not wanted
You need to use the brush tool
Brush selection edge with transition effect
Paint around a little
Method 2
Use the Lasso tool to create a selection on the picture
Right click and select [Feather] to set an appropriate feather value
Right click the selection area again and select [Reverse Selection]
You can see the reverse selection area. At this time, press the [Delete] key on the keyboard to see the effect
There may be some minor defects, just use the mask and brush in Method 1 to decorate
