Sorry I don’t know the technical term for what it is I’m asking for but I can show you with this video. Its from the indie game “Evil” and at 17:31 is the effect im going for. Its like the camera narrows and looks longer. Some type of Field of view trick.

I think you are looking for the Field of View of the camera. You can change it in script through Camera.fieldOfView. To change it on the main camera:

Camera.main.fieldOfView = 120;

You can also click on the camera and adjust the slider.
