Are you used to ACES tone mapped for your game products Now?在这里插入图片描述

首先,您知道ACES正在通过学院委员会推广统一色彩空间。

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

为什么? 为什么…学院委员会这样做? 知道这一点有助于我了解很多ACES。

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

ACES的最大部分旨在简化您所拍摄的相机和显示图像的设备(监视器,投影仪等)的色彩空间工作流程。

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)等众多相机和传感器通过其专有技术,色彩处理,
ACES开始于该学院提议使用每个传感器如何捕获其捕获的光信息的配置文件来创建色彩空间工作流程。

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.

这称为输入设备转换。 换句话说,每个照相机制造商和照相机型号的颜色配置文件用于统一称为ACES的颜色空间。

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.

由于ACES FULL实际上是一个巨大的色彩空间,因此对于VFX和后期制作无效,因此我们创建了一个称为ACESCG / ACESCC的色彩空间,这是我们最熟悉的色彩空间。

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转换后的色彩空间中工作时,将在ACESCg色彩空间中渲染渲染,并在ACESCg线性化状态下合成相机捕获的图像,并执行最终传送。
转换为所示设备的过程称为输出设备转换。
在此部分中,转换为每个设备代表的色彩空间的过程,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进行CG渲染时,同样重要的是将纹理分配给ACESCg。
ACES有一个参考渲染变换(RTT),它是最难理解的一种。
RRT是一个简单的想法,摄影导演(或称“看”)使用“外观”来创建图像感,这可以是电影外观,而不是光的真实表达,而是艺术表达。 该部分通常在ODT之前应用。
此类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.
