摘要 |
A flash photography system includes a first photometering device including a multi-segment photometering sensor having a plurality of zone sensors for measuring a pre-flash emission; a second photometering device including a single-segment direct photometering sensor for measuring a main flash emission; a weighting device which assigns a weighting factor to an output of each of the plurality of zone sensors; a calculation device which calculates a correction value based on each photometering value and the weighting factor of each zone sensor of the first photometering device, wherein an appropriate receiving light amount of the second photometering device is calculated in order to attain a compensation exposure for the main flash emission based on the correction value; and a controller which terminates the main flash emission after the light amount measured by the second photometering device reaches the appropriate receiving light amount. |
