Overview of how ambient light affects printed photos and how you should adjust the ambient light.To the article
Adjusting the monitor display conditions
After the ambient light has been adjusted, the monitor can now be configured according to the altered lighting conditions. Use the ColorNavigator calibration software, which is included with every ColorEdge monitor, to perform simple, quick, and precise calibrations. If the monitor does not have an integrated measuring device, you will also need a sensor.
Almost all of these sensors are supplied with their own calibration software. However, we recommend that you only use ColorNavigator to calibrate your ColorEdge monitor.
If the monitor rendering and photo printout are to be compared visually, the white point and brightness of the monitor must be coordinated with the photograph paper, upon which it will ultimately be printed. Fasten the paper in a position, which allows a simple comparison with the monitor, and follow the instructions below to match the white point and brightness.
The white point, brightness, and gamma value are used for calibration in ColorNavigator.
 White point
As mentioned above, the white point of the monitor should be matched with the colour of the photo paper, upon which it will ultimately be printed, as well as possible.
Find out the colour temperature of the fluorescent bulb you are using (e.g. 5000 K) and enter this value in ColorNavigator. If the white on the monitor has a slight blue cast after calibration, reduce the colour temperature of the white point and repeat the calibration.
White photograph paper sheets can be directly measured using ColorNavigator. This enables precise calibration of the monitor white point and brightness, taking into account ambient light and the colour of the paper.
In some Eye-One range models, the ambient light can be measured. This function is also supported by ColorNavigator. If you wish to use the function, click [Measure the target] to measure the ambient light. The measured value with x-y coordinate values is determined for the target white point.
If the white point measurement described in paragraph  is performed, the brightness adjustment can be skipped. If not, the brightness adjustment is very important. With a typical monitor, the brightness of photo paper that is seen at night under artificial light is equivalent to a light density of 80 to 100 cd/sq m. Of course, this value depends on the number of fluorescent bulbs and their distance from the paper. First, try to calibrate to 80 cd/sq m. If the monitor seems brighter than the paper, reduce the brightness settings and repeat the calibration.
 Gamma value
Set the gamma value to 2.2, regardless of whether you are working with Windows or Mac OS.
Calibrating with ColorNavigator on Mac OS
(15) If paper measurement with the sensor used is not available, enter the target values manually (brightness, white point, gamma) and click [Next]. For general applications, we recommend setting the white point to 5000 K and brightness to approx. 80 cd/sq m.
The ambient light has now been adjusted. The white point and brightness of the monitor have been coordinated to the white tone and brightness of the printing paper. To check that the colours match, you should display a white surface (such as an empty file folder). Drag the area to the size of the printing paper. Hold the printing paper alongside it and compare the colour impression.
