Lumen Automatically Adjusts the Brightness of Your Mac Based on What You’re Watching on the Screen
Mac: An app like F.lux is great for adjusting the screen temperature, but not everyone wants to look at an orange screen just to make it more readable. Lumen is a tool that automatically adjusts brightness without losing temperature.
Many Macs automatically adjust brightness based on the brightness it detects in the room, but Lumen does this based on the brightness it detects on the screen. So, if you are looking at a dark application window, it automatically becomes brighter. If it is all white, it will darken. Ultimately it’s most useful if you tend to use dark modes in applications or are often in a terminal window, but it’s a handy tool for anyone who isn’t a fan of how F.lux works but doesn’t want to be. blinded.
