Canon EOS R50: Missing check_for_new_images script and tethering without Zadig on Windows.

Software darktable
1

Hi everyone,

I am currently using a Canon EOS R50 on Windows and I’m trying to set up a tethering workflow in darktable. However, I have run into two specific issues:

  1. Missing Hotfolder Script: I have installed the Lua scripts repository, but I cannot find the check_for_new_images script under the ‘contrib’ (aportados) folder or any other category in the script manager. Has this script been renamed, moved, or deprecated in recent versions? I would like to use a hotfolder to import photos while using Canon EOS Utility.
  2. Tethering without Zadig: Is there any way to achieve direct tethering (Capture) with the R50 on Windows without using Zadig to replace the USB driver? I would prefer to keep the default Windows drivers if possible to maintain compatibility with other Canon software, but darktable doesn’t seem to recognize the camera otherwise.

I have already checked the ‘Official’, ‘Contrib’, and ‘Tools’ categories in the script manager but without success.

Any guidance on how to fix the missing script or a workaround for the driver issue would be greatly appreciated.

Thank you!

Where did you hear about a check_for_new_images script. I’m not aware of a script like that.

Hey and welcome! I don’t think you can tether without the Zadig driver.

"Hi Bill, thank you for your quick response. I probably got that name from an outdated tutorial. To clarify, I am using darktable 5.2.1 on Windows.

What I am actually looking for is a way to set up a hotfolder (a watched folder) so darktable automatically imports new images as they are added to a specific directory.

Is there a current script or a native feature in this version that performs this ‘watch folder’ functionality? My goal is to use Canon EOS Utility to download photos and have darktable import them instantly."

Note that you can use the “Copy and Import” feature to move files from the camera media to disk while importing into darktable at the same time.

Good point… I appreciate your observation.

I actually wrote a script awhile ago (7 years) named filetether which polls a directory to see if anything has been added. If a new file is detected it is opened in darkroom view, IIRC.

Let me pull it out, dust it off, and maybe apply whatever knowledge I’ve gained in the last 7 years to it and then I’ll post it here.

EDIT: I actually found that I had updated it. It depends on a Linux/MacOS feature to notify the script when a new file appears. I think I can create the same thing in powershell so that it will work on windows.

Thank you very much for your attention and willingness to review how feasible it is to increase darktable’s connectivity in the Windows environment for tethering.
