I think the first need is to add diagnostics to profiler packages to warn of light/flare problems; and to stop pretending it is straightforward point and shoot solution. The procedures must be described and beta-tested; lighting/target kits must be tested and made available for the reasonable price; and all that for the market that generally not only does not use raw, but even if they do, ask "the camera set f/16, how the exposure could possibly be wrong?" -- the subject is a small dark bird, with the sky as a background ;)

The marketing materials certainly don't help...they make it seem like all you have to do is hang a ColorChecker off your model's neck for one shot and you've magically got perfect color for the entire shoot.

When I was still wasting my time with it, I had to hand-craft an offsetting curve in the DNG profile editor -- and it was murder doing iterative approximations. Never could get better than sorta close.
