Andrew, I've addressed this multiple times. Let me try once again.
In the studio, I have a workflow that I've verified multiple ways, including empirically with spectrophotometer measurements and side-by-side visual comparisons, that, within the gamut limitations and minor (low-single-digit DE) variations we're all quite familiar with, I get output that's the same as the input.
When I apply the same process in the field, everything gives every appearance of working exactly the same way as it does in the studio. For obvious reasons, I haven't attempted to empirically quantify those results in the same manner as I have in the studio.
If this was a peer-reviewed journal, you'd be right to rip me a new one for sloppiness in verification methodology.
But this isn't a peer-reviewed journal, and I'd suggest that I've more than satisfied the burden of description for a forum such as this. That's especially the case since I've repeatedly described, in great detail, exactly what it is that I'm doing.
I'd at this point now suggest that, given your obvious interest in the subject, you owe it to yourself to attempt to replicate my findings, especially since you should already have all the equipment* and skills necessary to do so; the only investment you need is about as much time as it's probably already taken you in typing responses on this thread.
Cheers,
b&
*I'm assuming you've got a chart at least as good as a ColorChecker SG. It's not ideal but it'll at least work for a proof-of-concept demonstration. Better is a hand-made chart, but that's a lot of work.
