SUMMARY The advanced search and the filter panels are already quite complete, but I have a user case which I cannot carry out using digikam right now. I would like to be able to find which pictures do not have an EXIF or XMP date. Sometimes I (or someone else using the picture library) receive pictures via instant messaging, which do not contain any metadata. I usually use the Adjust Time Date tool to set the date (otherwise the date ends up being the file creation or modification date), but I know there must be hundreds of pictures without a date in the metadata, and need to be fixed. I don't know exactly how could that be carried out in digikam. Maybe an "Images without date" in the Filters panel, and then inside a list of checkboxes for the different dates (EXIF creation, original, digitized, and the same for ITPC and XMP). Or maybe adding a "Date" section in the Advanced Search, I don't know. On the other hand, I don't even know if these specific fields are saved in the database or are read from the picture on the go. For the moment, I use a exiftool script that lists pictures without date in a given folder.
Hi Marc, In fact, this is not easily possible. We can only search or filter for things that are in the database. Since we always need a date, if no metadata is present, the file date is used. This would actually only be possible if the images were analyzed again with Exiv2 or ExifTool. Maik
I see. I wasn't sure if that info was in the database. Anyway, I'll keep using exiftool for that purpose. You can close this request if you want.
