Cameras these days are computers with lens mounts. A calibration chart could be used to create a metadata profile one might refer to as "white balance on steroids". Many of the latest in lighting technologies have odd spectral spikes and dips that can cause color shifts not fully accounted for via standard color temperature and tint adjustments. By comparing actual values with nominal values on a couple dozen chips, a sophisticated offset LUT could be built. That LUT could be used for WYSIWYG monitoring, as the reference point in grading and as a multi-cam alignment tool. With some clever design the same chart could offer grid lines between the patches that could support various geometry correction protocols like lens distortion inversions.

Not sure what is needed to move this concept forward. Sure seems like a great way to leverage the technology already built in...

Very cool. So you use the Passport for this?

Yes, i think the passaporto and Macbeth are built in to resolve, but with enough feedback, they could probably incorporate many more charts.
