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 Pro Features (Mac only):

DarkAdapted Pro is available only to Macintosh users. For a small registration fee ($10 US), the following capabilities are enabled:

* A system-wide menu lets you control DarkAdapted from any program, and you can define system-wide keyboard shortcuts for almost any DarkAdapted Pro feature.
* Control displays independently, using separate control windows, or in unison.
* Use the RGB Sliders Window in any application. This window provides instant control of red, green, and blue values, via sliders or numeric input.
* Activate the Brightness Window in any application, and control screen brightness via a slider or the keyboard.
* Define your own Brightness keyboard shortcuts, allowing you to brighten or dim the screen from within any application program.
* Schedule unlimited gamma fades by time of day or relative to sunrise or sunset.
* Choose whether or not to start DarkAdapted at login, for the current user or for all users.
* Run any AppleScript via the system-wide menu or a global hotkey. Schedule AppleScript execution by time of day or relative to sunrise or sunset.
* Define Preset Sets that apply different gamma settings to different monitors, and specify a Preset Set to be applied at startup.
* Specify a minimum allowable brightness to prevent an unreadable display.
* Change presets via mouse scroll wheel.
* Move gamma sliders in unison, preserving or discarding relative gamma values, using the mouse scroll wheel.
* Share DarkAdapted Pro’s preference settings among all users, or specify that any or all users maintain their own individual preferences.
* Choose to hide the Mac OS X Dock icon.
* Apply Gamma Toggle keys to all displays at once, or choose to only apply them to the selected display.
* Create a custom icon for DarkAdapted’s system-wide menu.
* SHIFT-click the Dock icon to immediately open all control windows that you have previously closed.
* Employ expanded AppleScript support.
* Save and load shared preferences, so that mutliple users on the same machine may share settings.
