Prolost Levels
Level Up.
This preset for Adobe After Effects provides detailed control over the classic Levels effect. Levels is an essential too for manipulating color, but it isn’t always intuitive. Prolost Levels allows you to drive Levels with eyedroppers, printer lights, and more. Use it to remove color casts from graphical elements, as well as to do basic corrections to live action footage.
Prolost Levels uses expressions to control the built-in Levels effect, no third-party plug-ins required. Anyone can open a project that uses Prolost Levels, forever.
Prolost Levels is part of Prolost EDC, a free (or pay what you like) set of After Effects presets that I use every day.
