When saving a JPG image it fails preserve exif information. Steps to reproduce: 1, Open an image that has camera exif information 2, make a minor edit (I did colour levels adjustment) 3, Use File->Overwrite to save image. In the dialogue window I had the following options set (including the advanced settings): - Quality 98, Optimize - Progressive - Save Exif data - Save XMP data - Save IPTC data - Subsampling 4:2:2 (chroma halved) - DCT: Integer Expected result: image saved with original EXIF data present Obtained result: image lost all EXIF data Camera model for my images is a Pentax K100D and this feature has been working for my images in previous GIMP versions.

Hello Zoltan, do you have information on which version of Gimp you had installed before 2.9.4? 2.9.2-r2? Does this upstream ticket cover your case? Colors -> Decompose discards exif data https://bugzilla.gnome.org/show_bug.cgi?id=727780 If not, would you mind reporting a new bug upstream using https://bugzilla.gnome.org/enter_bug.cgi?product=GIMP linking bugs back and forth? Best, Sebastian
