我指用一般dc而唔係單反影, 通常我會用慢速同步或者後廉閃光影, 總之就慢快門 + 腳架 + flash, 但結果會發現張相嚴重偏黃, 唔開flash 就唔會,. 用canon 既a系同sony w系都有同一情況, 試過用唔同白平衡都解決唔到問題(但未試過自己set), 請教有夜景人像經驗既各師兄師姐, 開flash造成相片偏黃既原因, 同點影先可以令張相唔偏黃, thz！

用輕便機的話沒法接外閃可以用感應閃燈,但小心部份機型一開閃燈會強制轉去閃燈白平衡.這時可用我以前的方法.手持按外閃,由於用了腳架快門會有一秒或以上,係夠時間見到快門開先按閃燈的.以下有一張照片供參考,係用輕便機加手按閃燈影的.

thz, 篇文章對我有用,. 手持外閃亦係一個方法, 但唔知仲有無其他辦法呢, 一來唔想特登買個外閃, 另外for一般朋友聚會用亦唔想帶太多野...

單純靠輕便機內閃由於本身輸出細,好難再搞乜花臣.
其實都帶得腳架唔爭在帶多個外閃,市面上有一些用來安裝感應閃燈的金屬架,可以一邊放相機,一邊放外閃,然後裝在腳架上.
唔想買外閃可以考慮用連續光,我之前就用過一支強光電筒,好處係即時睇到效果,唔駛好似閃燈咁估估下,缺點係擴散角度比較細,手持的話由於人好難於按快門後立即移去適合位置,要舉高從高處照下增加擴散距離,而且連續強光好困擾被攝者,同埋其實都唔平,或者可以考慮下DV用的補燈

至於乜都唔駛買的方法我暫時未有

至於同你講用自設白平衡或者影raw果D人好明顯係信口開河,自己根本從來冇咁試過.

[icekinhk]

thx Philippe, 你既意見對我好有用。
我既問題唔係因為內閃弱, 而係開內閃會偏色(可能用內閃會自動轉去閃光燈白平衡), 連續強光雖然唔係100%明係講咩, 但一句"好困擾被攝者"已經唔會考慮(而且被攝者人數可能會有幾人), 聽完你講, 似乎只有開快門後再外閃...

"至於同你講用自設白平衡或者影raw果D人好明顯係信口開河,自己根本從來冇咁試過"---> 有d 人講既野我係唔會理

開flash造成相片偏黃既原因,
==> When the flash of a DC is on, the white balance is set to be day light.
Since the flash light is of daylight white balance, the color is correct only within the reach of the 弱內閃 . The color of the rest is the color of the ambient light which is tungsten (yellow)
It is therefore 開flash造成相片偏黃

同點影先可以令張相唔偏黃, thz！
==> When a strong flash (外閃) can cover most of the scene then the whole scene is illuminated by the day light (white balance) and the whole scene become normal ie 唔偏黃

A complicated white balance environment is a challenging job for even professional photographers.

Happy shooting !

偏黃o既係現場光﹐o岩色o既係閃光。
由於兩者色溫唔同﹐成張 tune o既話係唔可能兩者都o岩色。

方法1
企位少o的現場光o既位﹐減少現場光對主體o既照射。
好處:
簡單﹐唔使外加o的咩。
壞處:
所制於場地。


方法2
係閃燈上加上燈光 filter﹐令閃光同現場光色溫一致﹐都係燈光。
好處:
唔使避現場光。
壞處:
要加o野﹐減弱閃光。

睇來都唔容易解決到呢個問題...
anyway, 大致上已經明白, 唔該晒各位師兄!

用死日光WB咪得囉

[Philippe]

icekinhk,內閃弱最大問題係你已經冇本錢再在佢前面加filter,我都試過但輸出真係細到等於冇.

[Cosplay]

未必是當時的環境所引至。

因為一般輕巧的數碼相機，
內置閃光燈，大多數都是微微偏暖。

不過，樓主最好上載一張相片，
等大家可以了解當時的情況。

[icekinhk]

我都知機仔內閃弱再加filter = 無開閃光, 所以唔考慮加filter
唔post 相啦, 有人樣的, 而且唔係我, 背景嚴重偏黃, 背景係無限遠果種, 例如對面海既大廈, 又或者係山下既背景等等, 其實連人像都有偏黃既情況出現

[Cosplay]

如果 WB 有閃光燈選擇，應該會好好多。
