Alpha Compositing Modes

Romain Guy's Alpha Compositing Modes is an informative guide that explains the different types of alpha compositing modes used in digital imaging.

The guide covers the basics of alpha compositing, which involves blending multiple images with transparency or alpha channels to create a new image. It describes the different types of blending modes, such as normal, multiply, screen, overlay, and more.

The guide also details each blending mode's characteristics and how it can affect the final image. For example, multiply mode multiplies the color values of the two images to create a darker effect. Meanwhile, screen mode creates a lighter effect by inverting and multiplying the inverted values.

Alpha Compositing Modes further explains using alpha mattes, which use grayscale images to define transparency. It also includes sample images that display each blending mode.

This guide is useful for graphic designers, photographers, and anyone interested in digital image manipulation. It provides clear explanations of complex concepts and helps users understand how different blending modes can impact an image.
