Darktable uses gphoto2 for tethering. Does the standalone gphoto2 recognize your camera? If not, there is nothing dt can do....

cparadis777 commented 7 months ago

I was able to tether the camera using the troubleshooting steps found in the manual. I was able to take a test picture with the gphoto2 CLI.

MStraeten commented 7 months ago

was able to reproduce this with my R7 but just if not connecting the camera in the darktable GUI;) So: did you connect the camera in darktable (and just forgot to mention that in your steps to reproduce)? from the manual (https://darktable-org.github.io/dtdocs/en/tethering/overview/): After the USB cable is connected, go to the [import](https://darktable-org.github.io/dtdocs/en/module-reference/utility-modules/lighttable/import/) module in the [lighttable](https://darktable-org.github.io/dtdocs/en/lighttable/) view. If your camera is available for use, a new section should appear in the import module containing the name of your camera and a “mount camera” button. Click this button to connect your camera and three additional buttons will appear: “copy & import from camera”, “tethered shoot” and “unmount camera”. Click “tethered shoot” to enter the tethering view. When you are finished, press the “unmount camera” button before physically disconnecting it.

Hi there. I am experiencing the same difficulties with my Canon 5D mkII. Xubuntu, DT 4.4.2 installed from Ubuntu(snap), gphoto2 installed afterwards separately. Success in all troubleshooting steps in https://docs.darktable.org/usermanual/3.8/en/tethering/troubleshooting/ The import module in lighttable view does not show the additional buttons.

The snap won't see the separately-installed gphoto2.... You would need to add it to the actual snap package, but I don't know how that would be done.

@ralfbrown : Great hint. Removed the snap Darktable instance, installed from the binary package prepared for my version of Ubuntu on the darktable.org and tethering works!

Thanks a lot!
