Fill lightThe fill light is also moved, being placed on the opposite side of the camera from the key light and close to the camera–subject axis. It is important that the fill light not cast a shadow of its own in order to maintain the one-light character of the portrait. The only position from which you can really observe whether the fill light is doing its job is at the camera. Check carefully to see if the fill light is casting a shadow of its own by looking through the viewfinder.
