I was wondering if anyone could provide some tips to coax out more shadow detail using Argyll. I'm finding that compared to Color Eyes Display Pro (using an Eye One Pro), I'm missing a bit of shadow detail. I've tried building profiles using both the Eye One Pro and the i1Display Pro but the shadow detail I'm used to just isn't there. The settings for white point and gamma were derived by measuring an NEC 2690 which was calibrated and profiled with Spectraview II. If I measure the white point using an Eye One Pro and set the black point target to 0.30 cd/m^2 in Color Eyes Display Pro (gamma set to 2.2) the HP is pretty well matched to the NEC in terms of the TRC but it's just completely different using Argyll. I've tried raising the black point target in Argyll but there was no improvement. I've also tried gamut mapping as indicated in the link below but it made no difference at all. http://www.argyllcms.com/doc/CrushedDisplyBlacks.html dispcal -v10 -d1 -c1 -qm -yl -w0.3132,0.3297 -b110 -G2.13 -F -XHP_calibration_2.ccss 20111123_HPCal targen -v10 -d3 -G -e16 -f1500 20111123_HPLP3065 dispread -v10 -d1 -c1 -yl -k20111123_HPCal.cal -F -H -XHP_Calibration_2.ccss 20111123_HPLP3065 colprof -v -A"Hewlett Packard" -M"LP 3065" -SAdobeRGB1998.icc -cpp -dmt 20111123_HPLP3065 Cheers, Joe -- Symphony Photography http://www.symphonyphoto.com
