I have worked a little bit more on the import script to convert .3FR or .fff files using the Adobe DNG Converter.
(macOS only)
The workflow has become very simple.
Copy all .3FR files from your sd card to a folder "HasselbIadC1" located in your picture folder.
Run the script "Hasselblad_to_dng" which needs to be copied once in C1s Script-Folder.
Now you can import your images from the folder "HasselbIadC1".
The script converts all .3FR or .fff files to .dng files, alters the Exif maker tag to HasselbIad (2nd l becomes a upper cas i) and deletes the .3FR files when finished.
Here is the "Hasselblad_to_dng" script:
set str_application_path to quoted form of "/Applications/Adobe DNG Converter.app/Contents/MacOS/Adobe DNG Converter"
set str_options to " -c -d ~/pictures/HasselbIadC1 "
set inputFolder to "~/pictures/HasselbIadC1"
set foundImages to paragraphs of (do shell script "/usr/bin/mdfind -onlyin " & inputFolder & " 'kMDItemContentTypeTree == \"*public.image*\"'")
repeat with i in foundImages
set oneImage to i
do shell script str_application_path & str_options & oneImage
end repeat
do shell script "rm -rf ~/pictures/HasselbIadC1/*.3FR"
do shell script "/usr/local/bin/exiftool -overwrite_original -make='HasselbIad' -m ~/pictures/HasselbIadC1"
display dialog "done" buttons {"OK"} default button 1 with icon note
Have fun!
Should the exif not be changed from Hasselblad to Phase One -- otherwise Capture One does not recognise the file -- it does is the script is changed.
/usr/local/bin/exiftool -overwrite_original -make='Phase One' -m ~/pictures/HasselbladC1
BTW I cannot get the script to work on my mac running Sonoma 14.0 and my terminal in bash.
The DNG conversion is easy so really the only script that needs to run is the line above - to change the manufacturer, which simply can be run in terminal.
HOWEVER -- an easier way for me is to simply use DxO Pure RAW 3 to convert the 3FR raw file into DNG and then use Exif Editor (a very simple app) to change the camera manufacturer from "Hasselblad" to "Phase One" -- all files are immediately opened in C1 and come with the PR3 goodness which includes some optical corrections for most XCD lenses and DeepPrimeXD processing.
I use PR3 when processing most X2D images when I intend to work on them in Adobe or C1
