The following is one line from a linux focus stacking script
After shooting a stack of Nikon *.NEF raws I use rawtherapee to edit only one raw from the stack. Save now.pp3 in the local directory and then invoke the following to create a corresponding stack of *.tifs (in a ./tifs directory), all edited as per the first one.
rawtherapee-cli -o tifs -p ./now.pp3 -b16 -t -Y -c .
What syntax would I use to do the same thing with darktable? (with now.pp3 as now.xmp)
Ah. Perhaps I need to wrap this in a loop:
for file in *.NEF
darktable-cli $file now.xmp tifs/$file.tif
