Hi Mikolaj,

Your tiff looks very dark. Nevertheless all areas show sufficient detail.

Tested calibrating the same camera for cinepaint last week as follows:
load raw with dcraw (standard) no gamma, brightnes or something like
this, only a simple bitshift to use the upper 14bit of the raw format
and calibrate with the lcmsprofiler under linux. Works perfect.
Note, I implemented the bitshift in cinepaints raw plug-in.

Problems occured in the first place while trying to apply gamma or
birghtness before the calibration.

Marti,
is Your profiler somehow sensible to non linearities in the target image?
Scarse did it very well, but has other problems like back swapping curves.

... ah, now it comes back in my mind - more important:
Your target seems to be a simple reflective - high glossy.
You need an very carfull lightning to avoid any! reflections on the
patches. Very difficult.
The target I used was the C1 from Wolf Faust. Look at www.coloraid.de for
more information. It is an A4 non glossy IT8.

regards
Kai-Uwe Behrmann
