枫下拾英 / 摄影艺术 / im a newbie to photographer, if you can explain the following basic concepts a little you'll be greatly appreciated.i looked at the pbase pics and always saw there are some words like that: 1/125s f/4.0 at 50.0mm iso800 , what's that mean? thanks!

俺试试:1/125s 是快门速度(秒) f/4.0 (光圈大小,越小光圈越大,光圈和速度组合决定胶片暴光量) 50.0mm 是镜头焦距(数字越小越广角,200-300mm 相当于望远镜)iso800 胶片的感光度,对光线的敏感程度,800适合光线很暗的场合和高速运动物体

使用大光圈(Z)

简单的说,光圈越大(数字越小),景深越浅,景深是指最近的清晰距离和最远的清晰距离的之间的一个范围,你说那种照片就是简单的使用大光圈,譬如下面这张,,,

这个问题留给器材派,俺不懂了,

关于数码相机的景深,器材派权威详解。

单反以外的所有数码机,在近距、微距拍摄时,才能体现比较明显的景深控制。比如这个,F/4.6, f=26.4mm, 物距约15cm。

我不是器材派,只不过对数码了解一些。同样焦距、同样光圈大小,光学相机、数码单反和纯数码相机的景深是不一样的。比如同样100mm焦距,光圈F=4.0 结果你会发现纯数码很难达到浅景深,数码单反略好些,光学相机效果最好。
