I think I may have finally found a working base for the scanner machine’s calibration! And it also seems likely that the feature and trailer will now use the same WB/tint (or at worst maybe +/- 1) as the rest on the same stock. It will probably take up to ten working days to fine-tune it and verify it across tons of frames across a few trailers and bits of a couple of features. But if it all works out, finally I should have a 1.0 of the calibration ready and can start processing final 1.0 versions of everything. I hope!
