DarkAdapted is an application program. It controls the amount of red, green, and blue in your screen gamma so that you may, for example, preserve your dark adaptation while using your computer. Gamma fades can be scheduled, AppleScripts may be scheduled, and system-wide hotkeys can be set up to execute AppleScripts and gamma fades.

DarkAdapted is being used by astronomers, planetarium operators, graphics professionals, medical professionals, airline pilots, air traffic controllers, and others worldwide to provide flexible, dynamic control over their monitor's screen color response. People with monitors that appear too bright (such as owners of certain iMac models), also find DarkAdapted to be valuable. Users may define an unlimited number of gamma presets, and invoke them via global hotkeys, by menu selection, or by typing the first few letters of a preset’s name.

DarkAdapted Applications

Dark adaptation — view screen in shades of red or green.

Reducing display brightness — turn down the brightness with a touch of a hotkey or at scheduled times.

Reducing monitor/display hum or buzz — a common cause is running an LCD backlight at less than 100% brightness.

Turn the backlight to 100%, then use DarkAdapted to reduce the brightness.

Photographers — after color calibrating your display with a professional device, use DarkAdapted to tweak the colors for special applications.

Scotopic sensitivity — those with sensitivity to certain colors can often find relief via DarkAdapted’s color adjustments.

Colorblindness — the display can often be tweaked so that color coded maps, etc. can be properly interpreted by the colorblind.

…and much more — we receive many reports of solutions involving DarkAdapted in addition to the above.
