I stumbled upon the Darktable and would like to give it a try to process photos of art pieces such as paintings.
The predefined base curves for Nikon Cameras produce much different results in comparison to my Nikon’s D3100 JPEGs.
Manually made base curve looks horrible even-though I think I followed all instructions correctly. (readme.md and video below)
Processed them like this
for each raw in the folder do darktable-curve-tool-helper -s “NIKON-D3100-100.dat” “raw”
after that darktable-curve-tool -s “NIKON-D3100-100.dat” -z -e “one-of-raws” -n 16 > insert-curves-for-NIKON-D3100-100.sh
script if you wish
Computed curves are deformed pdfs
Can you please suggest any hints to make it work?
Thanks in advance!
