Raw development looses Exif/XMP data


Recommended Posts

When developing a Raw image with an XMP sidecar Affinity Photo loses vital metadata (similar to darktable and raw therapee). Only Lightroom preserves the metadata.

I attach a screenshot of Geosetter and an Excel table summarizing the result. While non of the programs is perfect, Lightromm is the only raw converter with a decent handling of metadata. Affinity is good, albeith not perfect, when loading from jpg and exporting to jpg. It would be nice if the raw converter would keep the metadata.

Thanks

That is because the sidecar files are crested by Lightroom and ACR for their own use.they contain a record of the operation that the Adobe software has applied to the raw image to produce the developed version. Some graphics software will utilize these (they are fairly simple xml files). Affinity does not read these files, but they are not lost, just not used.

There ave been feature requests to add the ability to read and utilize this information. You could add your support to one of those threads.
