Balance Out Display Technology
A free piece of software called Calibrize uses colorimeter measurements to calibrate the screen on your laptop. Hue, expressed in hues per inch (abbreviated “HPI”), is the measurement that Calibrize uses. You can quickly measure the maximum and minimum colors with Calibrize.
Calibrize’s effectiveness can be attributed to the fact that it employs two techniques for measuring color: a traditional observer method and a digital camera method. Between the two, there are certain distinctions. With a traditional tester, you would snap an image with the camera after setting the Calibrize threshold to a number you think is accurate. That is, a brief gamma test would be conducted.
