Linda adjusted the gain, apperture, and the focus of the camera to get a better picture and then she sends the message. The "Camera Configuration" screen can also come up if Linda selects "Video" from the "Configuration" option on the menu bar. The window on "Camera Configuration" allows Linda to view how she looks on the camera. However, if she configures her camera while another user is connected to her, that user can also view the result of the configuration and can tell Linda if her picture looks too out of focus.
