Missing data in 'image information' #6686
Comments
I guess this is because dt checks for those (and possibly some other Exif tags) only in the Exif.Photo IFD, while DNGs only contain Exif.Image? |
Yep, almost everything is pulled only from Exif.Photo here. Focal length info is curious though, as it uses Exiv2's own accessor, no idea though if that one checks all possible IFDs... |
Turns out the Exiv2 accessors do the right thing. |
One has to remove the DNG files from the collection and re-import them unfortunately, I don't know any other way of triggering metadata re-read... |
The test that I made was with a re-imported image. Renamed and without
sidecar.

But does it have this patch applied, or you just built clean master? |
When using a DNG format file that was produced by a Huawei camera-phone I note that both the aperture and the speed information is not available in the 'image information'. I questioned this problem over the dt-forum and have confirmation from an other that this appears to be the same problem on other (Android) cameras.-->
When the DNG file is exported to a JPG file all of the image information including the aperture and speed are correctly written to the EXIF file in the JPG.
I am running the daily git ... Manjaro .. Arch ... XFCE
