应该在什么时候使用进行手动曝光

摄影师需要丰富的经验,才能自由设置快门速度和光圈并以适当的曝光进行拍摄。 因此,大多数人以“ P”模式或“ A”模式拍摄。

但是,即使您使用这些图案在同一地方拍摄,如果改变构图,曝光也会改变。 即使亮度条件相同,曝光也会因构图而变化。 拍摄者难以准确判断曝光补偿值,并且操作麻烦。

因此,尽管您想改变构图,但您始终希望以相同的曝光进行拍摄。 您可以先让相机确定曝光(在“ P”模式或“ A”模式下确定快门速度和光圈),然后更改为“ M”模式并将快门速度和光圈设置为该值。 在“ M”模式下,只要不改变快门速度和光圈,摄影师就可以始终以相同的曝光进行拍摄。

相机

The photographer needs considerable experience to be able to set the shutter speed and aperture freely and shoot with appropriate exposure. Therefore, most people shoot in "P" mode or "A" mode.

But even if you shoot in the same place with these patterns, the exposure can change if you change the composition. Even if the brightness conditions are the same, the exposure varies due to the composition. It is difficult for the photographer to accurately judge the exposure compensation value, and it is also troublesome to operate.

Therefore, although you want to change the composition, you want to shoot with the same exposure all the time. You can start by letting the camera determine the exposure (determine the shutter speed and aperture in "P" mode or "A" mode), then change to "M" mode and set the shutter speed and aperture to that value. With "M" mode, the photographer can always shoot with the same exposure as long as the shutter speed and aperture are not changed.
