I've download the snapshot tonight, and make some test on it. The quality calibration seems to work as expected, until the 1200 dpi. I don't know exactly what is a quality calibration, but I guess it would had solve my previous problem since we clearly hear the stepping motor during the calibration process. But I have always problem above the 1200 dpi. The resulting scan is not always bad. I explain : - at 2400 dpi : I have done several try, at least a dozen. Sometimes it's all dark, sometimes all white, sometimes a succession of colored bands, and sometimes I have a good scanning, but at least it doesn't scale the entire selection I have made on the preview screen. And I have always the shaking between line. (and I am sure I have the latest snapshot of the snapscan backend and of xscanimage frontend) - at 3600 dpi : it's in part all the same, except that when it's work, the scan cover the entire selection I have done. The shaking seems always visible, but I am not sure because of the quality of my film. Those problems arise with or without quality calibration.
