Understanding Halftone Effects

The halftone effect converts continuous-tone images into patterns of dots of varying size. This technique was originally developed for printing — since printers can only apply solid ink or not, they simulate shades by varying dot density. The comic book aesthetic is the most famous application, but halftone patterns appear everywhere from newspaper photographs to pop art.

When you look at a comic book up close, you see rows of dots. From a normal viewing distance, your brain blends those dots into smooth gradients. This optical illusion is what makes halftone work. By reducing your photo to dots of different sizes, the tool creates a striking retro effect that transforms ordinary images into something that looks printed.

Adjusting the dot size changes the texture. Small dots preserve more detail but give a finer texture. Large dots create a bolder, more graphic look closer to Roy Lichtenstein pop art. The monochrome mode produces classic black-and-white newsprint style, while color mode preserves the original hues with a dot-screen treatment.
