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.

Features:

Try DarkAdapted Standard or DarkAdapted Pro before you buy, as often as you like.

Customizable gamma presets. Use predefined settings, create your own, and manipulate your presets with ease. For example, use the “Dark Red” setting to preserve your dark adaptation. Or create a preset to deal with monitor characteristics or viewing conditions.

Adjust gamma values via sliders or from the keyboard.

High-resolution sliders allow you to adjust red, green, and blue video components individually and in real time. Sliders can be set to report gamma values as percentages or as raw gamma values.

Keyboard control of gamma color values, using raw gamma values or percentages. Switch between percentage/raw display with a press of the spacebar.

Ganged Slider Mode allows you to control all three gamma components in unison, optionally preserving the gamma’s relative values between adjustments.

Small screen mode hides advanced controls, minimizing the use of valuable screen real estate. The control window may also be hidden entirely.

Select a preset by typing the first few letters of its name.

Export and import gamma presets to and from disk files. Many sample presets files are included with the download.

Full AppleScript support (on Mac OS), including a sample AppleScript with the Mac OS download.

“Gamma Toggle” keys offer a quick return to full brightness. Modifier keys are fully assignable, and display in the control window to remind you what they are.

Switching to gamma presets is performed via smooth fades, never abrupt shifts in screen color or brightness.

Gamma fade duration is user-configurable (from instantaneous to two seconds), and slider controls may be set to update in real time during the fade.

Almost all windows “remember” their positions on your screen.

Saved gamma preset can be restored when DarkAdapted is launched, and reset when DarkAdapted quits.

Automatic refresh preference can override gamma adjustments made by screen savers or other software.

Automatic or manual checking for updates via the Internet.

Useful display features show gamma changes’ effects on selected text, as well as text on different backgrounds.

Useful numeric and graphical readouts of gamma values.

Includes the same powerful night vision technology as ScopeDriver, a full featured telescope control program.

Excellent, hyperlinked documentation can be opened from within DarkAdapted.

And many other time savers and productivity enhancers.
