What does the Quadtone effect change?

Quadtone divides luminance into four coordinated color regions, retaining fine tonal transitions while building a richer four-color print-inspired grade. The strength control determines how much of that treatment replaces the unedited appearance.

Which photos work best with Quadtone?

Choose Quadtone for portrait color grading, product images that need a unified palette, or social posts prepared as a coordinated series when the source has clear detail and balanced exposure. Start with a lighter setting if it contains severely clipped channels, color-critical documentation, or images where an exact product color must remain unchanged.

About the Quadtone effect

Quadtone remaps channel and luminance relationships while retaining the source geometry. Its intensity control blends the processed output with the uploaded pixels, so the edit can remain restrained or become the dominant look.

Upload a photo, adjust the Quadtone intensity, compare its processed preview with the source, and download the finished result.

Less suited to: Quadtone is less reliable on severely clipped channels, color-critical documentation, or images where an exact product color must remain unchanged.
