The invention relates to a control apparatus for the wireless remotely controlled power adjustment of flash-light units (4a to 4d), in which a light measuring probe (7) is connected to a control centre (1) of the apparatus, whereof the reported actual value of the light is compared with a reference value of the light derived from the sensitivity of the film and the selected aperture and that according to the differential value therebetween, the control centre (1) varies the power level of all the flash-lights (4a to 4d) independently so that the actual value corresponds to the reference value. In this way the manual adjustment of the power level is dispensed with, so that the photographer standing behind the camera (6) need solely initiate a trial flash, whereupon the control centre (1) adjusts all the flash-lights (4a to 4d) to the required power level in readiness for taking a photograph. <IMAGE> |
