A film exposing equipment such as motion picture cameras and still cameras is equipped with photometric devices measuring the quantity of light falling upon the film to be exposed. The display device showing the user the measurement result comprises a succession of light emitting diodes adjacent to each other, determining the measuring scale, these diodes being powered and hence lit up at all times with the exception of the single diode among them, which, unlit, constitutes the mark giving the measurement result. The succession of light emitting diodes comprises at predetermined intervals, specific diodes different from the other diodes by their dimensions and/or colors, constituting specific marks on the measurement scale. |
