heya, this 60D case is really unfortunate. the way we handled defaults in the past isn't very good.. in a sense that if we now replaced the apparently broken 60D "enhanced matrix" it'll break history stacks for all old images.
we should probably store at least a 3x3 matrix in the parameters of the input profile module such that it doesn't depend on an external icc file. now if you select an external profile, you'd have to move the icc file around with your library to be able to reproduce the same results. the darktable-chart workflow is somewhat better, because it does store all required information in the history stack (and it's editable and a more expressive mapping/lut). so if you are going to create a profile for a chart.. i'd recommend you do it with darktable-chart as a preset/style for the colour lut module. i think i should prepare an extended tutorial how to do this. cheers, jo On Mon, Oct 23, 2017 at 8:10 PM, Thomas Werzmirzowsky <werzi2...@gmx.de> wrote: >> Gesendet: Montag, 23.
