adding images to an existing group

After importing images (roll film) into DT 4.8 and made some rejections, I would like to group the images accoding to one criteria (say, family, landscape, buildings)… I select some of them and create a group.
Hence, 2 questions:
1.- can I give a name to every group?
2.- can add images to an existing group?
3.- can I move an image from a group to another one?

I didn’t find my way, so I suspect I am misunderstanding what groups are intended for…

Thanks

Not that I’m aware off. Applying tags probably is the better approach for this kind of grouping task

Yes. By selecting both the grouped images and the image in question and using the grouping shortcut. You should use “collapse grouped images” to easier select the whole group.

Yes. It’s the same procedure as adding an image to an existing group. You may find it easier to ungroup the image in question first though.

It sounds like you are trying to use darktable groups to be like lightroom collections. I suggest that you use tags with hierarchic like Michael suggested. I have 4 branches in my tags (year, place, people and event). Every image gets a combination of those (eg. 2024, France | Paris | Louvre, Family | John Smith, Vacation | Museum). You could create a 5th branch (landscape), with different categories (landscape | buildings, landscape | bridges, landscape | mountain).

Thanks, this helps me a lot

After reviewing tagging documentation (DT 4.6 manual, page 230 to 235 section 8.3.5.11) I am confused.

Does the dictionary store just words or strings, or it allows a certain structure or hierarchy (like xml-style)

I really can’t follow the doc when talking about paths, tags, nodes and free nodes. And how can they be used when searching

Looks like search capabilities are limited to bulk text search.

Date is a quite important data, and it can be derived from the datestamp of the file

I would appreciate any hint to better understand tagging.

thanks

But usually, you do not want to use that date, as it is set and changed by the operating system.
You’re usually better off using the dates from the metadata.

Darktable allows for at least 5 time stamps:

  • EXIF datetime : set by the camera when you take the picture (i’d never change this one, but I try to keep my camera set to my local time)
  • import timestamp : when did you import the image into darktable
  • change timestamp : when did you last edit the image
  • export timestamps : last export
  • print timestamps: last printing.

And for me, none of these correspond to the timestamps from the file/operating system… (OK, the OS “last modified” timestamp on the sidecar file has the same value as the “change” timestamp, without the seconds).
