- Make a screen shot of your desktop
- Check with a viewer and see no EXIF data
- Load it in gThumb to use its crop feature, crop and save
- Check again with a viewer and see that gThumb added EXIF data including the gThumb version
In the mean time I’ve started to use other software to crop screen shots but I am still puzzled why gThumb always adds EXIF data ?
My favorite general image viewer is nomacs.
