clstrong>ss

targ targ targ targ targ targ当我们凝视一幅优秀的风景照片时,有时心中不免自问:“为什么这幅照片从前到后都拍摄得很清晰?我也clstrong>ss

有用光圈f/22,为什么景深还是差了那么一截?”回答这个问题,有必要先看一下光圈,焦距和对焦点的作用clstrong>ss

和相互影响。首先光圈控制景深,大光圈如f/4景深浅,相反小光圈如f/22景深就大。拍摄风景时光圈的设置一clstrong>ss

般在f/8到f//a之间。要慎重使用更小的光圈f/22或f/32,这是因为光圈太小,容易产生衍射现象,使图像糊。ss

当光圈缩小时,对焦点前后的景深就会扩大。通常对焦点的前三分之一和对焦点后的三分之二为有效景深。如ss

果你对焦在无穷远(远处的山脉),只有山脉前三分之一的景深用上了,山脉后面的三分之二的景深就浪费clstrong>ss

了。把对焦点朝自己方向移,换句话说,在你近处对焦,那么前后景深也就有了。这就是专业foll师们为什clstrong>ss

么推崇“对焦画面三分之一”的道理。ss
