The tunnel-like construction of the test images allows for the visual examinationĪnd set-up of the display's linearity. The third test image serves the pure gray calibration You can find a bigger test image for controlling and calibrating gray rendition You can use the small square in the middle,Īs viewed from sufficient distance it always should be pure gray. Setting up the blue channel is the most difficult. Just begin on top and move on counter-clockwise. The second color image serves fine tuning of gamma calibration separated If it is not, the test images flickers diagonally. If your Gamma calibration is correct you should see only a general flickering. Vertical areas in this image change their location two times in a second. (Please allow yourīrowser to show such images continuously.) The halfes of the horizontal and The first test image is an "animated GIF". Set-up tools of some graphics cards allow for such system-wide gamma corrections, ![]() Adobe Gamma (comes with Photoshop for Windows). The case, correct the gamma value using an adequate tool for system-wide In brightness (the transition should not be determinable). Respective halfes of the horizontal and vertical areas should match exactly If your gamma value is set up correctly at 2.2 then the Below you will find two color test images and a grayscale test image for ![]()
