[以相機作為武器]

1.什麼是手動曝光?
2.仲有就係點解有d機明明有得決定快門速度(例如:1/2000-14),
但係又話佢不支援快門先決?

[Philippe]

1. 應是自行決定快門及光圈值吧.
2. 那個應是最快與最慢快門值吧, 不可以自行設定的.

Philippeo兄說的沒錯
所謂手動 曝光
也就是說光圈值和快門值兩者都由用者自行設定
技術和經驗不足的話容易做成Over同under
曝光過度(爆光)
同
曝光不足(相片昏暗)

有時睇相機spec會見到快門速度由1/2000 - 15s
呢個只係部相機可以做到呢個速度
而未必會俾User自己set

想set 的話
部機就一定要有 "全手動mode" 或者 "快門先決mode"

注意嘰係
有全手動未必一定有快門先決
因為快門先決係你set 快門速度
由相機幫你set光圈值去達到正常曝光
Manual就全部自己set

其次就係
部份機種(如Canon A40)嘰所謂手動曝光mode
唔會俾曬全部光圈值同快門值你玩
只係得幾個setting

You control both the aperature and shutter speed. It doesn't mean that you don't need a meter for checking the exposure, you may still rely on the in-camera meter, or use a hand-held one.

Shutter-pirority mode mean you set the shutter speed, and the camera set the aperature level according to your shutter speed selected.

Yes, even you can select the shutter speed, it is possible that there is no shutter-pirority mode in your camera. Which means that even you can select the shutter, the camera will not automatically select the "best" matching aperature for you.

Hope this helps.
