摄影中的概念

光圈

光圈是决定曝光的三种因素之一。光圈罩包含小金属板,可打开和 关闭以允许光通过光圈并进入相机。光圈的大小与光量相关:光圈越 大,允许的光线越多;光圈越小允许的光线越少。

光圈大小

最小光圈 中等光圈 最大光圈

光圈大小由称为焦距比数的值表示。焦距比数表示焦距除以镜头

直径。例如,如果具有 50 mm 焦距的镜头的焦距比数为 F2,则光 圈的直径为 25 mm。(50 mm/25 mm = F2)焦距比数越小,光圈越 大。

光圈中的开口称为曝光值(EV)。曝光值增加(+1 EV)意味着光量

增加一倍。曝光值减少(-1 EV)意味着光量减半。您还可以使用曝光

补偿功能微调光量,细分曝光值为 1/21/3 EV,以此类推。
