The latest update to Apple’s popular MacBook Air line should tell us that there isn’t much new under the sun for traditional PCs. The MacBooks got a speed bump, a slight lower price tag, but otherwise the next great thing for personal computers may never ever see the light of day again.
Hardware improvements these days are incremental, but that’s increasingly the same with software. Take a look at Black Light. This inexpensive utility brings a few useful visual effects and other features to the Mac’s screen, though aimed mostly at Mac users who work at night, in the dark, or in poor lighting conditions.
Black Light can invert the Mac’s screen; reversing blacks and whites, which makes it look like a negative of the screen.
The inverted screen can be useful in some situations, but so can HDTV luminance adjustment, as well as over exposure, color filter and dim screen– all additional screens in Black Light.
The Overexposure mode replaces white grays with white, which removes stripes, which then makes white the background of most app windows.
The HDTV Luminance Adjustment changes the screen to match some HD television screens when connected to the Mac via HDMI.
Of course, Dim Screen and Color Filter are obvious.
Cycling through the different screen options in Black Light can be handled through the Dock icon, or global keyboard shortcuts, or the Menubar icon. To remove the screen adjustments entirely, simply quit Black Light.
Not every Mac user needs Black Light, but for those who work in odd lighting conditions, the Color Filter can be especially beneficial. For Mac users with digital attachments with HDMI connectors, adapting the luminance range can eliminate a few screen issues, too.
