aperture priority

基本解释

Aperture priority mode works in much the same way.
光圈优先模式基本相同。
If you camera has an aperture priority setting, use it and set the aperture to f-8, f-11, or f-16 if possible. This will give you greater depth of field and cause the shutter to slow down.
因为较长的曝光时间，所以你需要一个三脚架来保持稳定，当然还要使用自拍模式了，使用光圈优先模式，然后把光圈设置到f8甚至更小，这将会使你获得很大的景深，同时让快门也慢下来。
Since aperture is the main event in aperture priority mode, you may not need to press the aperture button; simply rotate the command dial and look for the changing numbers in the LCD status screen.
就光圈优先模式来说，光圈是最主要的参数，所以你并不需要再按光圈按钮，直接转动指令盘并且在LCD上查看数值变化即可。

Additional tweaks include a manual volume adjustment (as opposed to the automatic gain the cameras usually employ), a brightness or RGB histogram display (this function, like some of these other features, has been available for a while as a hack), shutter and aperture priority modes have been added for movie shooting, and the audio sampling ramp has been bumped from 44.1KHz to 48KHz.
