Hello, I'm new to Argyll and the list. I'm trying to make a camera profile using the ColorChecker SG. The tif file is ~25 MB, shows the chart edges, and is located in the Argyll ref folder. When I enter: scanin -v h4_ag_kf32_l+l_rm_130509.tif ColorCheckerSG.cht ColorCheckerSG.txt I get: TIFFOpen: h4_ag_kf32_l+l_rm_130509.tif: Cannot open. scanin: Error - error opening read file 'h4_ag_kf32_l+l_rm_130509.tif' Might someone be able to diagnose the problem? Thank you, Alex Jamison
