I suspect the issue might be on my end / configuration / misunderstanding, which is why I didn’t open a bug / issue for it:
I read in many places that Darktable is supposed to be able to filter by tags, but my Darktable does not seem to support that. For example, darktable 4.0 user manual - collections lists ‘tag’ under ‘metadata’ for collection filters, but I have no such option (despite having images with tags):
Is that something I need to enable or activate somewhere in order to see it ?
It’s not a bug. Not all filters are implemented on that part by now. You could find tag filter on collections module only actually. The developer of that part didn’t have time until now and will begin to work again on that part to add other filters soon. Maybe tag will be there for 4.6 if he can.
In the collection module, click on ‘film roll’ and you will find the tag. You can also right click on the tag in the tag module to filter for that tag.
So if all search options should end up under “collection filters”, will they be removed from the “collections” module? Or, if they stay there as well, what’s the reasoning to provide the same filters in two places?
(One difference I think I noticed is that the “collections” module creates a new film roll, where the “collection filter” only limits what’s visible from the current film roll, and the resulting image set is not stored as a film roll. But that’s a bit thin im(ns)ho…)
@rvietor: I will not answer that. You will find some threads on that forums that discussed that. I let you search for collection filters threads. You will have many answers.
Huge difference in my experience.
The collections provide a way to show a group of images to work on.
With the filters you can narrow that group down easily - and repeatedly across multiple collections because the filters stay until you remove them. Also the filters keep your selection alive, which is very helpful when you turn a filter off, so you can see the filtered images in the context of the whole collection.
Thank you, @grubernd, I hadn’t grasped the effect of the independant modules, allowing a filter to be “reused” over several collections. With that, the “collection filter” makes a lot more sense.
