摘要： In a strobe controlling apparatus, there are provided respective information outputs for outputting respectively the guide number information GV, film sensitivity information SV and object distance information DV, a judged diaphragm value is determined by the operation of GV+SV-DV from their outputs, the above-mentioned diaphragm value is compared with a predetermined value memorized in advance, in case the above-mentioned diaphragm value is smaller, the diaphragm will be controlled and, in case the above-mentioned diaphragm value is larger, the flash amount will be controlled so that, particularly, at the time of strobe photographing, the short distance exposure may be prevented from being over-exposed and a proper exposure is made possible.
