No not really. It's not required. It is a process to attempt tweak the
rendering. I could use sliders provided and the info palette which doesn't
affect the internal profiles one bit.
What you've yet to define is how creating a camera profile isn't
fundamentally the same as creating a scanner profile (the original point I
asked about). Certainly the algorithms are not the same but the approach
appears to be; shoot some target in some controlled situation. Compare the
reference to the measured data. That works well for scanners. Works very
well for printers and displays. Sometimes works with cameras, sometimes
doesn't. At least that's my experience and those of others. Could it be the
way the fundamental process is structured? How is profiling a digital camera
different than a scanner?
