Consistent monitor brightness

Since I do a lot of photo stuff, I use a calibrated/profiled monitor at home. While I also calibrated/profiled my MBPs screen, it’s way inferior, but good enough for the first edits on the go. One problem: the calibration is dona at a specific screen brightness, so to get accurate colors, the brightess setting should always be the same.


  • I use Shifty to turn off Night Shift when starting Lightroom, Photoshop, Photo Mechanic and other photo stuff.

  • I have a Keyboard Maestro macro that sets the brightness to 85% whenever I activate LR, PS, etc. I just starts an AppleScript:

    tell application “System Preferences”
    reveal anchor “displaysDisplayTab” of pane id “”
    tell application “System Events”
    delay 1
    set value of slider 1 of group 2 of tab group 1 of window 1 of process “System Preferences” to 0.85
    end tell
    end tell


  • doesn’t work with auto brightness (yet?)

I’m in the exact situation as you and I’ve thought of doing something like this but never got to it. Thanks for the inspiration and script, I’ll get it set up asap. :+1:
