摄影中的概念

闪光

光是拍摄中最重要的元素之一。然而,随时随地获得足够的光量并 不是很容易的事情。使用闪光灯可让您最佳化光设置,并营造不同效 果。

闪光灯可帮助在光线较弱的情况下获得足够曝光。在光线充足的情况 下也很有用。例如,闪光灯可以用于补偿拍摄对象阴影的曝光或在背 光情况下拍摄清晰的拍摄对象和背景。

闪光灯指数

闪光灯的型号指的是闪光灯的功率,获得的最大光量由称为闪光灯 指数的值表示。闪光灯指数越大,从闪光灯发出的光量越多。当将 ISO 感光度设置为 100 时,闪光灯指数是透过从闪光灯到拍摄对象的 距离乘以光圈值得出。

闪光灯指数 = 闪光灯到拍摄对象的距离 X 光圈值

光圈值 = 闪光灯指数/闪光灯到拍摄对象的距离

闪光灯到拍摄对象的距离 = 闪光灯指数/光圈值

因此,如果您知道闪光灯的闪光灯指数,您可以在手动设置闪光灯时

估计闪光灯到拍摄对象的最佳距离。例如,如果闪光灯的闪光灯指数 为 GN 20,距离拍摄对象 4 米,则最佳光圈值为 F5.0
