- Thread-topic: GMB ProfileMaker 5.0.5 is out!
Do you think us plebs using EyeOne Match can expect a revised version which
will carry any improvements to the default PM5 settings (default size,
Chromaplus, D50 lighting, neutral grey and OBAs on) through to Match?
I would also appreciate a "lay term" (or "newbie") explanation of the
improvements that have been introduced. I thought there wasn't a lot of
room for interpretation in any intent except Perceptual.
Thanks
Steve
