How to make a wide-angle effect of an ordinary photo?

You can use Filter-Distortion-Spheroidization, the mode setting takes precedence horizontally, and the number parameters can be set according to your preference.

The gradient blur on the right can be Layer-New Fill Layer-Gradient, and then adjust the transparency of the new layer in the layer window to cover the image on the right with the gray gradient of the new fill layer.

You can also use the feathering method, just paste the picture on a layer larger than the original picture, feather it in the selected box, and then cut it. You might do the same thing. Not much to say. If you need me to do it, send me a photo of 13@qq.com at 2857558.
