Hello, I have recently scan a photo under linux and I notice (it was not the first time) that the colors were too dark, tern. So I have scanned it under windows and the colors were good.
Linux scan : http://vrac.dumontweb.com/scan-bad.jpg Windows scan : http://vrac.dumontweb.com/scan-good.jpg So i have tried to calibrate it using the option calibration in xsane but it has changed nothing. After I have seen that I need to make a fine calibration using gamma/contrast/luminosity. But I am far from being a specialist and I have a lot of difficulties to obtain a good result. I succeed to improve the colors but it is not perfect :((( I have also try to understand how the calibration works and why windows is able to produce a good result. I think that I have understand how it8 / icc / icm work. So I have retrieve the icc file for my scanner under windows and I have tried to apply it. I have done : scanimage -i cnz005.icc --resolution 600 > image.tiff or convert -profile cnz005.icc before.tiff after.tiff But nothing happened and the image was still the same. Do I have understood how it works ? Can I apply an icc file to my image ? And how ? If it is not possible, how can I easily make a fine grain calibration ? Thanks a lot in advance for all your answer. Philippe OS : linux 2.6.16.19 SMP PREEMPT scanimage (sane-backends) 1.0.18; backend version 1.0.18 scanner : canon lide 30
