Missing EXIF on export?

I’m running 2.10.14 on a PC. When I open a photo it contains a ton of metadata. Following a series of edits and an export, the volume of metadata is severely reduced (eliminating the data that would be shown on say: a camera discussion forum). I use another editor which also does this. My main reason for transitioning to GIMP was to preserve this metadata for subsequent sharing. Any ideas?


What ate your Preference settings? https://docs.gimp.org/2.10/en/gimp-introduction-whats-new-metadata.html

Thanks Mica! My preferences seem to be correct. In playing some more I’m wondering if scale might have something to do with the loss? Things seem fine until I scale.

Like scale the image size? That doesn’t seem right.

Hi Mica,
As a novice GIMP user I’m stumbling but after fiddling with things I’ve figured out how to do what I wanted with fewer steps and which preserves the metadata. - Gary

I happen to experience the same problem: camera and lens data are gone since December 2019

Stefan - does this happen with all opened images? Do you have your PREFERENCES sorted out? Does this happen after a particular sequence of operations ending with an EXPORT. As I was muddling around earlier I found that I could get where I needed to be by using a more direct set of steps and then my EXIF data was there on EXPORT as well as complete.

Can you detail your previous and current workflow? Sounds like a bug we should report.

My workflow hasn’t change a bit: I open my .NEF in darktable, edit and convert them, then export to TIF 16 bit, 2560 px on the long side into a special folder.
From there I open the photos with the Gimp, heal some skin problems or do some dodge & burn before exporting to .jpg

Since some day in December 2019 the camera and lens data are gone. This bug is consistent in the experimental and in the stable versions of darktable 3

Have you set up the metadata export in DT? Have you verified that the data is there in your tiff export?

December is a while ago… has your compute platform changed? New software? OS updates? Anything that might have overwritten what was stable in December?

yes, the metadata (my name as author and the license) are exported correctly, show up in the Gimp and finally in the photo’s exif, too, But all technical info (camera, lens, aperture, focal distance and such) are lost

not really - I am no distro-hopper (unchanged since 2007) and I tend to use computers up until they fall apart.
