How to create pinhole photography effect with Photoshop filter

In the middle, use the round tool of the marquee tool to select the area, and set the feathering value according to the requirements. Use the magic eraser to select the middle point, become transparent, and edit and clear it. Make it a pinhole with an imaginary edge, exposing only part of the background. For reference.
