A good thread with an explanation by Erin Chan is here.
Thanks for that link, Chris. I had read that too. Still, I don't see what that should do for a pure studio work, for fashion and products?
towards the end of that thread:
If all you shoot is under daylight such as in landscapes then a single table is all that's necessary.
and than, as mentioned in this whole thread here and elsewhere, DNG "profiling" wont do that much for you. Just think, that middle formats RAW converters, like PhaseOne/Mamyia/Leaf, do not use DNG. Only ICC profiling there. And if you believe them, it has theoretical and practical reasons.
From what I understood till now, DNG is/was geared to photographers shooting under various lighting conditions and/or not willing to invest in professional means like targets and a ICC software (the now legacy ProfileMaker ... ~2K U$D). But what interests me, and I am certain a lot of others, is a pure studio perspective with tightly controlled lighting conditions. I don't mind to spend time, effort and money to get to the best result.
