I just wonder which camera mode is more often & better to be used:-

(1) Full Auto ? When ?
(2) Program ? When ?
(3) Shutter Priority ? When ?
(4) Aperture Priority ? When ?
(5) Full Manual ? When ?

F給家人或朋友用的時候，P給剛剛學攝影的時候，s影運動或賽車比較高速的時候，影水也很好，慢快門和高速快門有唔同效果，A影微距和影人像比較多用，M在影樓或一些比較高要求用，其實都冇一定什麼時候用什麼功能，各師各法，只要張相出來靚就可以了。

Many Thanks!

M係用??逼曝光不足或過度曝光 又可以控制快門光圈, 例如影星星

Then when do you use exposure compensation?

Some people say he deliberately make the exp. comp one step up (+1) or one step down (-1) to exaggerate its contrast, is that used often?

In a shutter priority mode, how do you know which shutter speed is to use in a particular setting (PLUS the function of the flash, etc.)?

同意cherrykenny所言：「各師各法」！

我習慣使用光圈先決，無什麼獨特之處，習慣而已！而用光圈先決時，多會增加2/3級捕光。(視乎情況！)

如在同一光源和時間許可下拍照，會用m mode，出來的效果會比較「準」。

Some text book also suggest to use AV mode more often in portrait photographs esp. when the setting is some indoor places.

[cherrykenny]

多謝，但我部相机在多數情況下都會under，所以我會加3/2捕光，影完再看看再決定。

Some says it is rather "under" than to "over" expose, as you could always fix an "under" exposed image in photo editing software.

An "over" exposed picture may be very difficult to do post-editing

光圈的多少對你當時的拍攝最為重要，就用av mode 囉！例如影人像時景深的多少對你而言相當重要，那麼用 av mode 或 m mode 會較為方便。

同樣道理，快門的多少對你當時的拍攝最為重要，就用 tv mode 囉！

[leepsj]

How do you choose a suitable shutter speed / aperture value ?

That's a problem esp. for an inexperienced amateur like myself.

Do you have any rule of thumbs?

[cherrykenny]

所以現在會影RAW，後期處理自由度會大Ｄ，同時現在相机多數會有即時看看捕光資料，所以唔會差太多。

但係我聽人地講...如果你唔用盡histrogram右邊高光o既話, 就會晒左個sensor, 因為大部分SENSOR的photon都會用來處理高光,所以影o既時候要盡量用盡佢,之後再post processing就會有最高質素...只限raw

[madxngai]

"An "over" exposed picture may be very difficult to do post-editing"？
真的嗎？

我多以 raw+jpeg 拍，jpeg 用來出相，raw 用來改相，最近暑假往沙巴，部份相 overexposed 2/3 級，以raw 執相後沒有問題呀！

To madxngai,

Thank you for your advice!
