Overview

The Halftone effect allows you to simulate the look of a printed halftone image. Halftone patterns are commonly used in printing processes to reproduce continuous-tone images like photographs using a limited number of ink colors.

Halftone breaks down the smooth tones in your image into a pattern of dots or shapes of varying sizes.

The effect divides your image into a rectangular grid of cells. Within each cell, it calculates the average brightness value. It then renders a circle whose size correlates with the brightness - the larger the shape, the brighter the tone.

By varying the sizes of these rendered shapes across the grid, the halftone effect achieves the illusion of smooth gradients, even though the image is now made up entirely of simple dots or shapes.

Controls

You can adjust several parameters to control the halftone pattern:

• Size: Determines the width and height of each cell in the halftone grid pattern.

• Scale: Controls the relative maximum size of the rendered circle within each cell

• Rotation: Adjusts the orientation of the overall halftone grid pattern.

• Luminance: Determines how much the brightness values in the original image influence the size of the rendered shapes. At 0, all shapes will be the same size regardless of brightness.

• Grayscale: Converts the halftone effect to a black and white output, removing any color information.

• Invert: Original color will pass through the entire cell except for the rendered circle.

• Pass Through: Allows the original image colors and brightness to show through any areas of the halftone pattern that would normally be rendered as full black.
