Description José Oliver-Didier 2022-02-01 21:14:44 UTC 
SUMMARY
Add view option for separating/grouping images by camera or device


STEPS TO REPRODUCE
1. Launch Digikam 7.5.0
2. Select an Album with images taken using diffrent devices/cameras
3. Go to menubar and select "Views" -> "Separate Items"

OBSERVED RESULT
- No option for "Camera" or "Device" exists

EXPECTED RESULT
- Option to separate/group 

SOFTWARE/OS VERSIONS
Windows 11


ADDITIONAL INFORMATION
- Windows Photo Gallery had a similar option for grouping devices using the EXIF Camera "Model" and "Maker" data into a single grouping option. It happens that some camera makers repeat the "Maker" name in the exif "Model" so Windows Photo Gallery would not repeat the maker's name. For example:

Case 1:  Maker="Google", Model="Pixel  3" would appear as "Google Pixel 3" as the grouping item.
Case 2:  Maker="Canon", Model="Canon EOS REBEL T3i" would appear as "Canon EOS REBEL T3i" (instead of "Canon Canon EOS REBEL T3i")

- This grouping option is quite usefull when working with multiple devices and cameras and one wishes to apply specific metadata based on camera make/model.

I programmed it as a test for the camera category. However, I knew beforehand that it would be very slow. Why? Technically, we have an item info that reads a lot of information from the database once and then keeps it in a memory cache. The photo information is not cached because we don't need it in the view. A lot more work is also needed so that building a view with several 10,000 items doesn't take minutes. Incidentally, the same applies to the location information. I don't think we will implement the category according to locations, as there are already wishes for a sidebar for locations.

Ok, it's not entirely correct. We have a cache for the image metadata. But it's too slow...
