Welcome to Linear Workflow in After Effects. We are going to start off going over how light behaves linearly and how our vision system perceives light non-linearly. Then, we will learn what video gamma space is and why we use it to store standard digital images. After that, we will go over some of the problems that occur when you composite in video gamma space. We will see all the advantages of a 32-bit float using a Cineon file, and we will also learn more about the advantages of working in linear gamma instead of video gamma. Then we will set up a project in linear color space and see what After Effects is doing behind the scenes. Finally, we will put theory into practice and composite a forest fire in linear gamma, learning how to render it out and comparing it to the same shot in video gamma. Software required: After Effects CC 2015.

Introduction and Project Overview
Hello, I'm Evan James. No matter if you're compositing visual effects for feature films, or motion graphics for commercials, understanding and using linear workflow will bring all the beauty of how light behaves in the real world to your projects in After Effects. In this series of lessons we'll be using some beautiful videos of the real world from Dissolve. Before getting started we'd like to say thank you to Dissolve and their contributors, MS Photographic, and Juan Jose _____ for their videos. We're going to start off by going over how light behaves linearly and how our vision system perceives light nonlinearly. Then you'll go over what video gamma space is and why we use it to store standard digital images. After that we're going to see some of the problems that happen when you composite in video gamma space, in particular when you add. We will see all the advantages of 32-bit float using a Cineon file, and learn more about the advantages of working in linear gamma instead of video gamma. Then we're going to set up a project in linear color space, and see what After Effects is doing behind the scenes. Finally we'll put theory into practice and composite a forest fire in linear. Then we'll learn how to render it out and compare how it looks to the same shot composited in video gamma. So with that let's get started.
