For utmost precision in Monitor Profiling,
if I have both a Sprectrolino and a DTP92, assuming an application that
fully supports either devices (forget a spectroradiometer like a CM-100,
which I just can't afford), in your opnion, which instrument is by design
going to yield the absolute best measurement of a Monitor? Bearing in mind
that the Spectrolino, in emissive mode, is limited to sample every 10nm,
whereas the DTP92 is filter based. Anyone ever made the comparison?
I have tested true spectros versus colorimeters using the same software, and
find that the theoretical advantages of the spectrophotometers don't
necessarilly translate to actual advantages in the resulting profiles.
I have seen this too. Although where I had a problem, the spectro
built the better profile.
Remember, when all is said and done, we are applying these profiles in a
rather primative manner; at best there are three phosphor values, a white
point and a gamma...
This is not necessarily true. Several monitor profiling packages -
ProfileMaker comes to mind but I am sure there are others - build
profiles that have LUT's. So rather than the simplistic matrix
information typical of working space profiles we have the selective
color correction ability of a table-based profile working for us.
I have found larger profiles of this type have solved some problems
for me in the past but admit I have not had the chance to fully test
if it was the table-ness of the profile that did the job.
