這次要來談的是在合成裡流動的顏色，特別是針對Nuke。我會從慣用的Linear-sRGB開始把前幾篇提到的內容串起來，再來比較和ACES不同的地方。基本上這些都只是特效產業裡的色彩管理-總論這篇的應用。 LINEAR-SRGB 以下畫面皆為ARRI官方網站所提供的影片素材。 上圖為ARRI自有的Alexa Wide Gamut色域以及LogC曲線的格式在Nuke裡不使用任何觀看LUT所看到的顏色。沒有太特別，就是一般所謂「看起來灰灰的」的log顏色，然後每個像素的數值都會位於0–1的範圍內。

There are already many many articles talking about ACES. Well, I’m not sure should I do the same thing on the same topic. But if I want to introduce other concepts I probably still need to do it anyway. Most of the definitions, explanations and introductions of ACES I will…

This time I’d like to talk about how color shifts in compositing, especially in Nuke. I will start from the basic workflow in traditional Linear-sRGB, then compare the difference with ACES. Basically, it’s just the implementation of the episode 1 of this color management series. LINEAR-SRGB The example footage is from…

大部分的特效產業的從業人員應該早就對LUT有些印象或些微理解。你的主管或總監會給你一個 .cube的檔案然後叫你用這個LUT去看你製作中的影像。但講真的，你知道甚麼是LUT嗎? 又或是你需要知道LUT是甚麼嗎? 好的，其實你並不一定要知道。但是如果對於LUT有更進一步的認識、了解LUT如何運作，那你也會比較清楚顏色在製作過程中的轉換，也會幫助你保持 …

If you are an artist you probably already hear this thing a lot. Your lead just send you a .cube file and tell you to view your image with this LUT. But really, do you know what is LUT? Do you have to know what the LUT is? Well, you…

我太懶了所以就基本直翻我上篇的原文。 原文連結 Color Management in VFX — Overall 在特效產業裡其實有不少從業人員不怎麼熟悉色彩管理。講白了，根本就是怕爆，連怎麼開始了解色彩這件事都不知道如何起頭，也不知道為何顏色總是不一樣，所以也就只能在未經色彩統一的情況下強行將顏色修正至一致。 了解色彩是在製作特效的過程中至關重要卻也 …

In the visual effects industry, there are still lots of artists who feel scared for color management because it’s quite hard to understand at the beginning and sometimes it’s too difficult for them to figure out why the color is not right, so they just continue to do their work…
