How to make photos like this?

It looks like someone added a fisheye filter to their lens.

As you can see, there is not a full 180 degree view. but only extreme distortion caused by an app.

Here is an add-on fisheye lens you can attach to your iPhone

Here is a sample using an actual fisheye lens

You will notice that the person standing next to the lens is in the shot and part of my foot is as well.

This shot using a fisheye, was with the camera on the floor of the basketball court a few inches from my colleague Max
