曝光多得制, 咁係應該校光圈大小定曝光補償?
兩者有乜關係?

咁白平衡有乜用? 同測光有冇關係?

測光同白平衡有乜關係?

有一連串既問題, 希望可以得到各位師父既幫手~ thx

最緊要係我想知佢地之間既關係, 我諗如果關係清晰左對我既影相技巧一定有好大幫助~

佢地= 白平衡,測光, 光圈, 曝光,iso

曝光多得制係測光問題,全手動的話較細光圈可解決.光圈先決的話相機會自動較翻快門去相同曝光值,問題得不到解決,應用曝光補償.
白平衡係適應唔同光源令照片唔會偏色,同測光冇關係.
測光就係找出適合的光圈快門值的方法.對相機來講有平均或點測光.
光圈係控制光線進入鏡頭的入口直徑. 控制景深及快門時間.
曝光就係相片形成啦
iso係感光度,越大曝光時間可以越短.但相片雜訊會增加.

philippe~ 唔該晒你~ really thx so much ~

但係仲有D 唔係好明~
==>''光圈先決的話相機會自動較翻快門去相同曝光值,問題得不到解決,應用曝光補償.''
可唔可以再詳細D 解釋下依句? 點解光圈先決的話相機會自動校返快門去相同曝光值? 咁校黎做乜?這時光圈是怎樣的? 有冇放大or 縮小?


咩叫光圈先決?and aslo 快門先決?

thx~~~~~

小弟都係新手,有錯既就更正更正la~
唔同既光圍大小可以影到唔同既效果(例如景深)
所以一定有得俾你較.
至於光圈先決同 快門先決,
就係影之前可以俾你較快門同光圍.

應該花心機o既唔係版友﹐係你自己。
去書包搵書睇下﹐買本返屋企﹐咁你就會明白o的基本o既知識﹐唔使下下問﹐又有 sample 睇。
一時唔記得又可以睇番。
朋友﹐即刻去啦﹐唔慳得o架。

我都建議你搵本書睇吓.
光圈先決係自行決定光圈,相機決定快門,曝光值跟據相機測光決定.所以你較大啲光圈,快門就會快啲,你較細啲光圈,快門就會慢啲,最終曝光值係冇改變,都係相機認為啱的曝光值.但相機唔係吓吓啱同埋有時可能拍攝者想自己加高或減低小小,這時就要用曝光補償.光圈先決的作用是因為唔同光圈對景深及光位銳利度等有影響.
快門先決係自行決定快門,相機決定光圈,曝光值跟據相機測光決定.快門先決主要針對移動物體,看你要涷結物體或做移動效果.

就算唔捨得買書, 圖書館都有大把攝影既書啦. 況且網上面都有大把好既網頁可以學到野.


例如呢個...

Agree with Philippe.

A tool book is needed for almost every photographer at the beginning.
I suggest you to buy one which teaches 135 film photography as these kind of reference book teaches more on photography techniques then those teaching only digital photography.

If you really wanna learn more in photography, you can always feel free to contact me using e-mail, avilable in my contact page.
I can tell you a lot more then I can tell here as typing chinese is far too difficult for me.........^^

Wish you enjoy photography!
