heya,
yes, this order of modules is intentional. changing exposure changes
the starting point of the colour transform.. those luts have been
created from well-exposed it8 charts, so heavily under- or overexposed
areas will not have any valid data points. also the colour transform
is non-linear and will do very different things.
and yes, i think in particular the velvia style has strangely lifted
blacks at times. that may need some manual intervention (delete some
data point and insert one near the blacks with a colour picker?), or
some additional calibration with more images than just one it8. would
need to think about how to do that in darktable-chart for generic
images where alignment isn't as simple as with an it8. potentially
it'll be enough to use multiple instances of the same it8 with
different exposure.
cheers,
jo
