How is the IT-8 colour calibration accomplished in practice?
In filmscanners, the IT-8 target is contained in the form of a framed slide that is introduced as a normaal KB-slide into the scanner and a preview is made of it. In this preview, the 22 x 12 colour fields are recognizable as also 24 grey fields thereunder from black up to white. By pushing the It-8 button in the SilverFast software, the calibration procedure is started where SilverFast shows a scan frame with a lot of small fields that has to be exactly adapted to the preview mask. This procedure is supported by an explaining dialogue. As soon as the mask is positioned rightly and has the right size, the colour calibration is started per mouse click. After one minute SilverFast has scanned the IT-8 target and compared the scanned colours with the referred table. The differences are filed afterwards by SilverFast in an ICC-profile archive. In the following scans, SilverFast uses the individually created profile automatically and embeds it in the image files. By this way, one gets scans
