The practice is as follows:ġst Step: Before starting the calibration, the monitor should be put back to the factory condition (e.g. The result is saved in an individual ICC profile that exactly matches the screen and that during the start of the computer is straight loaded to the graphical card and therewith provides a correct screen representation. But merely the measuring would be meanless, as the obtained valuehave to be compared with the reference values and the differences must be detected. It is only possible to achieve a configuration that is applicable for all pictures if the colours, brightness and contrast of the screen are objectively measured with a measuring instrument, a so-called colorimeter.
The human eye is not able to differentiate the intensity of the different colour channels. This might work exactly with this picture, but in the case of another picture, this subjective adjustments can lead to completely wrong colours and the picture can get much too dark. But many users think that this is achievable with the visual adjustments of the screen in which a model picture is simply compared with the representation of the screen and the determined deviations are corrected with the different controls of the screen menu.
The objective of a screen calibration is the right reproduction either of the colours as also the brightness and the contrast of the monitor. General basics about the screen calibration The toolset Datacolor SpyderX Pro is available in our online-shop.Īnd in almost all cases the answer is: "No, what for, and what is it at all, a screen calibration?" or "This is much too compplicated and also very expensive!" In the next chapters we will show on the basis of the Datacolor Spyder3Pro that a calibrated monitor is a condition for the exact colour reproduction in the digital pictures and that such a calibration neither is complicated nor much too expensive.
