Did you ever wonder how to replace the sky of an already rendered shot? Or how to turn a day scene into a night one? How to add 3D objects to camera footage with a natural-looking result? How to layer still images and movie clips and animate the result? How to add explosions, lens flares, depth of field, film grain, and shadows? How to simulate camera lens imperfections, such as vignetting and color fringing? How to color grade and completely change the mood of your video or image? Even relight scenes? Use masks and blurs? Maybe you never did but I bet you do now. And you can learn all about it in one terrific course by Daniel Nees. If you don't know that name, look him up: he's a compositor master who works on big productions (Marvel movies, Star Wars Andor). Blender's node-based compositor is a free and very capable toolbox. You'll learn to get everything out of it in this brilliant course by a brilliant teacher!
