唔該師兄^^
但是仲有一樣野唔明,白平衡都能調冷/暖色
咁相片風格中的"色調"功能和白平衡差不多??

Basically color can be described as 3 parameters

(1) Hue
(2) Chroma
(3) Luminance

And there are so many color system to describe these 3 color parameters in various color models, for example Pantone, Mussel...etc

色調 refers to as "Hue", sometimes it is called "Tone".
"Chroma" refers to as "Saturation"
"Luminance" refers to as"Lightness"

AWB is talking about color temperature, all color CANNOT be revealed UNLESS there is "Light", "Object" and of coz an "Observer", under different color temperature, different color will be revealed, for example a black suit in a boutique under tungsten light (around 2500K~3000K) may not be so "Black" under "Sunlight" (Around 6500K).....a "TRUE BLACK" or an "IDEAL BLACK" in clothing will usually contains some "Blue" light.

So you can regard AWB as how you reveal color in different venue, indoor, outdoor, flash light, rainy day, sunny day...etc

Thus color temperature actually affects 3 parameters simultaneously.

Hope it helps.^^

gavincheung ching, 這是我今天遇見最"爛"的GAG......XDD

一言以敝之, 紅色做例子

(1) 色調 (Hue) 是在說--> 乜嘢"紅", 紅都有好多種架嘛

(2) 飽和度 (Chroma/Saturation) -->即係問自己 "有幾紅先?" "紅到咩地步?"隻紅有幾鮮色呢?

(3) 光亮度 (Lightness/ Luminance) -->即係問自己"隻紅有幾光呢?" "係暗紅抑或比較亮的紅呢?"

(4)自動白平衡AWB / 色溫(Color temperature) -->即係問自己要係乜嘢場合見到隻紅呢? 响屋企D慳電白光燈見到呢? 還是响酒樓見到? 定係响個閃燈個1/3000秒flash duration之中見到呢?
