  • 光圈值越小,光圈越大;光圈越大,景深越小,曝光值/通光量越大(或曰设定曝光值下,速度越快);
  • 快门值越大,速度越快;速度越快,景深不变,曝光值/通光量越小【注:快门值小於一秒的分数值】
  • 通光量减半,相当于快门速度翻倍,或光圈值递增/光圈缩小,即曝光值减一;
  • 通光量翻倍,相当于快门速度减半,或光圈值递减/光圈变大,即曝光值加一;
  • 感光度越大,相当于快门速度越慢,或曰在设定曝光值下,速度越快;
  • 焦距值越大,景深越浅;物距越近,景深越浅。(决定景深的三要素:光圈,焦距,物距)
  • 焦距值范围:10~14mm(鱼眼),14~35mm(广角),85mm(标准),120mm以上(长焦);注:用于非全幅数字相机时,焦距值要乘以系数(佳能1.6/尼康1.5)。
  • 光圈值范围:全开(1),1.4,2,2.8,4,5.6,8,11,16,22,32(通光量依次倍减)
  • 光圈优先表:设定感光度100,光圈f8时的快门=1/1000(阳光下白亮物体),1/500(全晴),1/250(薄雾),1/125(多云),1/60(阴天);
  • 月夜曝光值:设定感光度100,光圈f5.6时的快门=1/60(满月);1秒(月牙);60分钟(满月月光,景中无月)
  • 星轨曝光值:设定感光度1600,光圈f2.8时的快门=30秒以上(无月、野外;星星以北极星为轴心,每小时15度角旋转)
  • 烟花曝光值:设定感光度100,光圈f8时的快门=1秒以上(使用快门线)
  • HDR预置:下载 Photomatix Pro Presets
