As suggested in another comment, the best way would probably to shoot in RAW (so you get the data directly from your camera's sensor) and then use postprocessing tools made for negatives. Darktable has a new module called "negadoctor" for this, see https://www.darktable.org/2020/08/darktable-3-2/ https://www.darktable.org/2020/08/darktable-3-2/ (ctrl+f negadoctor). Darktable also supports Lua scripting, maybe that could be used to automate a workflow.
