Alpha compositing is the process of combining one image with a background to create the appearance of partial or full transparency. Learn about the history, description, and comparison of alpha compositing methods, such as over, in, out, and premultiplied alpha.
The term "rendering" is also used to describe the process of calculating effects in a video editing program to produce the final video output. A software application or component that performs rendering is called a rendering engine, [1] render engine, rendering system, graphics engine, or simply a renderer.
A second high-contrast copy is then made from the first, rendering the backing clear and the foreground opaque. Next, a three-layer sandwich of film is run through an optical printer. On the bottom is the unexposed copy film. Above it is the first matte, whose opaque backing color masks the background. On top is the negative of the foreground ...
Adobe After Effects is a software application for creating and editing visual effects, motion graphics, and compositing in film, video, and television production. It can also perform basic editing, audio editing, and media transcoding functions.
Learn about the process of digitally assembling multiple images to make a final image, typically for print, motion pictures or screen display. Explore the mathematics, software and workflows of digital compositing, such as node-based and layer-based compositing.
Ambient occlusion is a shading and rendering technique that calculates how exposed each point in a scene is to ambient lighting. It creates a diffuse, non-directional effect that darkens enclosed and sheltered areas and can affect the rendered image's overall tone.
Blend modes are used to determine how two layers are blended with each other in digital image editing and computer graphics. Learn about the basic blend modes, such as normal, dissolve, multiply, screen, overlay, hard light, and soft light, and see how they affect the colors and shapes of the layers.
Ray tracing is a technique for modeling light transport in 3D computer graphics, simulating optical effects such as reflection, refraction, and shadows. Learn about the origins of ray tracing from Albrecht Dürer to Arthur Appel, and the evolution of ray tracing algorithms and applications.
