Hugin packages downloaded during the installation of DigiKam. Please post the log from the terminal as described here for MacOS: https://www.digikam.org/contribute/ Maik It works with JPG files without any problems. I see in the screenshot that you are using NEF files and I can reproduce the problem with that. A first analysis shows that when Exiv2 writes the metadata, the temporary TIF files are no longer readable. We can switch to ExifTool under digiKam-8.0.0 to write metadata. Then there is also no longer a problem with NEF files. Maik Git commit 3d3870f743c1c0309196595a444c77f435514902 by Maik Qualmann. Committed on 09/06/2022 at 06:47. Pushed by mqualmann into branch 'qt5-maintenance'. copy not original metadata over metadata already saved by DImg This destroys the image files with Exiv2.

Yes the interim solution worked for me too. When do you estimate digiKam-8.0.0 will be available to download?

My work flow is Nikon Z7 > Nikon's NX Studio > export 8|16-bit TIF image. Thanks again. -Steve Git commit 7efc95ba540bf1d758d42ac604d704c026b89d93 by Maik Qualmann. Committed on 09/06/2022 at 16:42. Pushed by mqualmann into branch 'qt5-maintenance'. better metadata handling in the panorama tool Setting metadata via QByteArray can buggy in current Exiv2 versions.

However, the Exposure Blending tool has already been fixed in this version. The Windows version cannot be compiled at this time. After that we will probably switch to alpha/beta versions of digiKam-8.0.0. Maik |
