The UI currently allows sorting items by Creation and Modified date/time. I'd like to be able to sort by the EXIF metadata "Date/Time Original"
The digiKam creation date is 99% the Exif.DateTimeOriginal date. If it is different for you, send me a sample image to my private e-mail. Maik
When using the Exposure Blending plugin, DigiKam sets creation and modification times for the output image to the time of the operation. As things stand now, that means the output image gets sorted hours or days later than the component images in the collection/album view. In the later step of my workflow where I copy tags/labels from a component image to the output image I am also setting the Exif.DateTimeOriginal on the output image to one increment (currently 1s, later .01s) after the component images. I am not changing the creation or modification times because I anticipate future cases where I need the accurate information in those fields. That workflow plus this feature request (which I'm trying to implement myself but will require DB changes (to ImageInformation, I think) which would be hard for me as an unknown to get merged) would allow me to sort the HDR images right next to the component images.
I understand that so, you reset the original time + x seconds afterwards, probably externally with ExifTool and not with digiKam's Time Adjust Tool. But then you have to read the metadata from these images again (Item Menu or Album menu or maintenance tool ) so that digiKam updates the creation date in the database. Maik
I am updating the original time, not the creation time, so re reading the metadata has no apparent effect.
