本人近日去左影夜影,用慢門4秒,光度幾好...我記得個陣用快門先決所以光圈auto的,之但係睇返d相...發覺d相唔sharp...點解呢?係唔係因為auto detect,光圈太大呢?借機比我朋友說,要開閃光燈,之但係跟機既唔係得個幾m而已~之後跟佢講咁影,係好左d,但係偏柔...唔係本身既色...究竟點解呢?

另一樣就是...光圈多大影景深才好呢?光圈幾細影景好呢?

最後一樣就是...M mode可唔可以關了曝光補償的?

照片不夠銳利有很多原因, 你的問題沒有附上照片, 很難妄下斷語, 常見的原因是:

(1) 相機晃動
(2) 對焦不準
(3) 鏡頭質素差 -- 大多數鏡頭的最大光圈都比較差

一般來說, 拍攝夜景可用 f/5.6 或 f/8, 視你需要的景深而定, 光圈大景深淺, 光圈小景深大; 同時, 拍攝靜態畫面(例如夜景)比較適合用光圈先決模式, 當然, 調較光圈後要留意快門值是否超出了相機的極限, 閃燈補光只是對有效範圍內的景物或人像有用。

手動模式下, 曝光補償是沒有作用的, 看測光錶讀數過度式不足, 就是「補償」了。

首先你有冇用腳架呢?4秒快門一定唔可以手持相機.
留意相機有冇暗環境對唔到焦的問題.影遠景其實手動無限遠最穏陳.夾硬自動就算相機話得都成日對錯焦的.
如果唔係影近景唔好開閃光燈,一來冇幫助,二來搞錯晒色溫,張相會變橙色的.

get a tripod heavy enough you can sit on it when it is fully extended.
You will always get stone stable image.

As for focus, you depth of field should well cover your error of focusing.

For get the auto exposure. It give you reference only. YOU NEED TO BLACKET

NIGHT SCENE IS WAY TOO CONTRACT FOR A BALANCNCE EXPODUERE. SHOOT DUSK STRAT INSTEAD.

用 Maunal.....刪到個光圈最細 (F8 或以上), 用番 4 秒咁上下, 腳架...再試影...唔夠光就 Shutter 長番少少

F stop should not be used more than you need as it will degarde the optcal quality. F/8 is not a rule.
