[Pkg-phototools-devel] Bug#991381: darktable: camera not showing in lens correction list and not recognised but is supported

[Stas Zytkiewicz]

Package: darktable
Version: 3.6.0-1.1
Severity: normal

Dear Maintainer,


I have a Canon 800D.
When I open a RAW image in darkroom the lens correction always fails to detect the camera. It will recognize the lens but not the camera. It tells me to add it manually.
But the list with Canon cameras doesn't show a 800D/Rebel T7i.
Looking in /usr/share/darktable/rawspeed/cameras.xml I see that the 800D is supported (also the 80D is in the xml but not in the list)
I have double checked that the exif data displays the correct camera type and the firmware in the camera is up to date.
Not sure why multiple cameras that are inside the xml file don't show up in the "manual add" camera list?

This is the out put of the exiftool:
exiftool IMG_1638.CR2 | grep -i "camera.*name"
Camera Model Name : Canon EOS 800D

The fix is to add the dependency for liblensfun-bin which contains the lensfun-update-data tool.
Then run the lensfun-update-data to update the lensfun dbase with all the supported cameras.
