Are you used to ACES tone mapped for your game products Now?在這裏插入圖片描述

首先,您知道ACES正在通過學院委員會推廣統一色彩空間。

First of all, you know that ACES is promoting the Unified Color space from an Academy Committee.

爲什麼? 爲什麼…學院委員會這樣做? 知道這一點有助於我瞭解很多ACES。

Why? Why … did the Academy committee do this? Knowing this helps me understand ACES a lot.

ACES的最大部分旨在簡化您所拍攝的相機和顯示圖像的設備(監視器,投影儀等)的色彩空間工作流程。

The biggest part of ACES aims to streamline the color space workflow of the cameras you shoot and the equipment that displays the images (monitors, projectors, etc.).

在其中,VFX或CG只是故事的一部分。

In it, VFX or CG is only part of the story.

阿里(Arri),索尼(Sony),佳能(Canon),尼康(Nikon)等衆多相機和傳感器通過其專有技術,色彩處理,
ACES開始於該學院提議使用每個傳感器如何捕獲其捕獲的光信息的配置文件來創建色彩空間工作流程。

Arri, Sony, Canon, Nikon, and so many cameras and sensors express their color with their know-how, color processing,
ACES started when the academy proposed to create a color space workflow using a profile of how each sensor captures the information of the light it captures.

這稱爲輸入設備轉換。 換句話說,每個照相機制造商和照相機型號的顏色配置文件用於統一稱爲ACES的顏色空間。

This is called an Input Device Transform. In other words, the color profile for each camera manufacturer and camera model is used to unify the color space called ACES.

由於ACES FULL實際上是一個巨大的色彩空間,因此對於VFX和後期製作無效,因此我們創建了一個稱爲ACESCG / ACESCC的色彩空間,這是我們最熟悉的色彩空間。

And since ACES FULL is actually a huge color space, it’s ineffective for VFX and post-production, so we created a color space called ACESCG / ACESCC, which is the color space we’re most familiar with.

在ACES轉換後的色彩空間中工作時,將在ACESCg色彩空間中渲染渲染,並在ACESCg線性化狀態下合成相機捕獲的圖像,並執行最終傳送。
轉換爲所示設備的過程稱爲輸出設備轉換。
在此部分中,轉換爲每個設備代表的色彩空間的過程,即Rec.709,Rec.2020,sRGB,P3等。

When working in the ACES-converted color space, the rendering is rendered in the ACESCg color space, and the images captured by the camera are synthesized in the ACESCg linearized state, and the final delivery is performed.
The process of converting to the device shown is called Output Device Transform.
In this part, the process of converting to the color space represented by each device, that is, Rec.709, Rec.2020, sRGB, P3, etc.

使用ACESCg進行CG渲染時,同樣重要的是將紋理分配給ACESCg。
ACES有一個參考渲染變換(RTT),它是最難理解的一種。
RRT是一個簡單的想法,攝影導演(或稱“看”)使用“外觀”來創建圖像感,這可以是電影外觀,而不是光的真實表達,而是藝術表達。 該部分通常在ODT之前應用。
此類IDT配置文件的集合是ACES。

When CG rendering with ACESCg, it is important to assign a texture to ACESCg as well.
ACES has a Reference Render Transform (RTT), which is one of the hardest and most difficult to understand.
RRT is a simple idea that a director of photography, or “Look”, uses a “look” to create a sense of imagery, which can be a film look and not a realistic expression of light, but an artistic expression. This part is usually applied before ODT.
The collection of such IDT profiles is ACES.
