A method for the recording of pictures, preferably living pictures, by means of a camera (2) and simultaneous recording of corresponding sound by means of one or more microphones (6) being displaceable in relation to the camera (2), that one or more signal wave fields are formed, each passing closely outside or touching a boundary surface for the recording field of the camera. For the formation of said field signals are transmitted from one or more signal wave transmitters (1), and the relevant signals are received and transmitted, from one or more microphones (6) to respective microphone guiding receivers by the transmitted possibly reflected signals. Thereby is achieved that it is facilitated to avoid erroneous recordings, where microphones unintended are taken into or are visible in the edge of the picture field of the film.
