Can ps solve the problem of insufficient depth of field in portrait photography?

PHOTOSHOP can solve the problem that the depth of field is too long and the protagonist is not prominent, but it can't solve the problem of incomplete coverage before and after the depth of field.

After the photo is taken, the scene has been recorded on the memory card, and the information lost due to the operation can no longer be retrieved. PS can erase the redundant parts, but it can't increase the lost information.

Using PS, you can simulate the blur of the clear edge of the photo center, or you can simulate the gradual blur, but only simulate it. The best way is to master the aperture and distance when shooting.
