Summary
This review was originally posted on VersionTracker.com.<br />This is a well thought-out program. Besides inverting the screen, it has options for 'hide stripes', dimming the screen (with a slider), and a nifty color filter. All of the options are selected via check boxes and can be used in any combination. You can also control whether the effect is activated at launch and when the dock icon is clicked. The user interface in general is good. The only thing I'd like to see added is a slider for saturation Ã¢?? from full greyscale to normal.
Excellent Little Program

This review was originally posted on VersionTracker.com.<br />Very nice. Thank you. asaxton: FYI, at least on my powerbook, that key combo you meantion inverts to grayscale black and white. On the other hand, this program does a true inverse, which means colors are inverted instead of being greyscaled. So I'm gonna keep using this :)
Well Done.

Brilliantly simple

This review was originally posted on VersionTracker.com.<br />This is a fantastic tool for powerbook users, especially while writing/working on trains and planes in low-light situations. The simplicity of simply toggling it on or off with a click of the dock icon makes it very habit forming.
elegant, simple, useful ...save on eye strain

Developer’s Description

By Michel Fortin

Apply screen effects such as inverted color, color filter, or 16-235 luminance for certain HDTVs.

Black Light applies visual effects to the screen by changing its gamma curve. You can invert colors, darken the screen beyond what's usually allowed, apply a color filter, or apply the 16-235 luminance gamut expected by some HDTVs.
