X-Rite ColorMunki Smile I met by a contribution from photokinaTV and can be ordered immediately due to the low purchase price. The package includes a measurement device with USB cable and counterweight, quick start guide and installation CD. First, the software needs to be included. Driver installed on the PC (only possible with administrator rights!). A reboot is required before commissioning. Then: Plug gauge to a USB port and start the software by clicking on the desktop shortcut. The user interface on the screen immediately (position measuring device in the designated area of the screen, measuring process by clicking on the corresponding button start) course. About 5 minutes test colors, black, white and gray tones are displayed and measured. Then, the monitor is automatically generated by means of a color calibrated and activated profile, and you can check the changes based on the before / after view of photos. I've performed the calibration for my desktop PC / Laptop and LCD (beginners products!) And am thrilled. Finally on both devices identical colors! Overall, the appearance of the image reproduction after calibration is warmer and richer in details. For example, skin tones are natural, green values and fresh black and white pictures rich in gradations and smooth transitions. The manufacturer recommends a week (due to low time requirements of routine safe easily possible) to use the colorimeter; ie well but at the same time that screens age more quickly than expected from your users!
