A method for taking image of face which is executable on an electronic device requires a speaker and a camera. An activation of the camera is detected and the speaker is controlled to emit sound from an audio file to draw attention of a target. If the face of the target is not facing the camera for a predetermined duration, a volume of the emitted sound is increased or another audio file replaces the currently played audio file and the camera is triggered to take an image of the target when the target is fully facing the camera.
