I want to ask about portrait photography, how to PS effect after shooting, and cut it like this!

To tell the truth, there is no trace of Ps in this photo, and all the effects are taken at one time. And it is not difficult.

First, the sun is behind and above the graph. This is the edge of hunger and the edge of clothes. The face is obviously made up, and there is a big reflector in front to fill the light.

As for the background, it's really not worth mentioning. With such a distant background, any lens can achieve this degree of blur.

good luck
