Just imagine you are digitalizing a magazine with 100 slides in batch processing for example with the magazine scanner Reflecta DigitDia 6000. But that would make the scan process considerably more complex. Now you could say: "Well, then I'm going to adjust the colours at the scan process with the scan software!". There it would make more sense if this fault would be eliminated at the source - the scanner. So one and the same image fault possibly needs to be corrected thousand or ten thousand times. If the scanner makes specific image faults these faults have to be corrected for every scanned picture in the image editing software. But this leads inevitably to image degradation because every single change of a finished image file means a loss in image quality.
HOW TO ADJUST COLOR ON EFILM LITE SOFTWARE
So you have to use an image editing software to correct those faults. This means that a picture from the scanner is not identical with the original. Why you should calibrate your scanner?Īs already mentioned every scanner generates image files with specific color faults. What that means and how this exactly works we want to show you on this page. In order to get a correct image file the scanner needs to be calibrated. If our output device – the monitor – is calibrated (more information on our website screen calibration) but the input device – the scanner - is not, then although we have a correct display of the image file, we do not have a correct image file itself.
This process is called calibration or profiling.
Eventually they also have to be adjusted with ICC-profiles. These have to be defined with a reference color space through a comparison of set and actual values. Every input and output device generates certain color faults when image data processing.
To understand whats going on you have to learn a few things about colour management. In our online-shop you can buy SilverFast Ai Studio with IT-8 targets for scanner calibrations.
