I am trying to linearize my workflow of doing panoramas using Hugin and Darktable. My current workflow looks like this:
- I do all of the linear (or scene-refered) operations in Darktable
- Export as 32 bit floating point TIFF
- Stitch in Hugin
- Reimport the Hugin TIFF in Darktable and do the rest of the operations on the panorama (tone-mapping via filmic, local contrast, etc)
My problem comes from picking the color space for step 2. If I pick Linear REC2020, then Hugin forces me to operate under its HDR workflow, meaning that I have fiddle with their exposure merging options to avoid creating ghosting. If I export in sRGB, Hugin lets me only stitch the images and no ghosting appears, but I am not sure if Hugin does operate in a linear space when using sRGB images for input and I’d like to avoid using a smaller colorspace for intermediate steps.
Any pointer would be appreciated.
