From ESOUI Wiki
This function zooms the third-person gameplay camera out. If the player is in first-person view, the camera will automatically switch to a third-person camera at maximum zoom.
When camera zoom is bound to the mouse wheel, calling this function is equivalent to moving the mouse wheel backward by one notch.
for i = 1, 3 do CameraZoomOut() end d("You should be zoomed out a little more now.")
