Hi, 1) I'm looking for a way to add a (in this case linear) vcgt to a profile which was made with qtMonitorProfiler.exe (from lcms 1.09). Does someone have an idea how to do this? Are there free tools which help me with this task?
Regarding the monitor profiler I have some additional questions: 2) qtMonitorProfiler.exe from lcms 1.09 was available as a binary. Did I understood it right, that the support for the MonitorProfiler was dropped with latter versions of lcms? 3) What's the relation/difference of pf.exe (regarding monitor profiles) to qtMonitorProfiler.exe? pf.exe seems to have lost the ability to create LUT based profiles or to use a measurement sheet to create the profiles. Is this right or is this just "hidden"? Are there changes how the Matrix profile will be created by pf.exe or qtMonitorProfiler? 4) I want to create a generic profile for a certain monitor and needed to average the profiles. These where the steps I did: a) I calibrated some displays with pf.exe (and an EyeOne Display2). b) Used icc2it8 to get the "measurement data" (of course not the real measurement data, but sort of) and to average the data. Then I would use qtMonitorProfiler.exe to create a new profile. But I found that using icc2it8 and then directly converting the it8 values back to a monitor profile will loose precision. For example when a monitor profile has a gamma value of RGB (2.09; 2.15; 2,2) the resulting recreated profile will show an averaged gamma for all the channels, which might be a gamma for RGB of 2.12 (or something like that -- I haven't noted the real values). Now I will use Gretag's MeasurementTool to make the it8-sheets and to average them and then use qtMonitorProfiler.exe to create the monitor profile, but I'm still curious to know if the loss of precision for the gamma curves is a "bug" or unwanted feature or if that was a designers choice for a specific reason? Looking forward to hear any ideas or pointes.
