I just ran into the same problem when converting RAW into TIFF, see
https://imagemagick.org/discourse-serve ... 71#p167971.
It took me some time to find out that the problem was created solely by ImageMagick that deleted the Exif information during the conversion TIFF --> TIFF. And yes, there is no way of changing this by -define or -set. So this is a bug that I am going to report.
The solution is Exiftool by means of which you may just transplant the Exif information from one image to another:
Code: Select all
magick input.tiff output.tiff
exiftool -overwrite_original -TagsFromFile input.tiff output.tiff

This is the official answer of the development team:
The TIFF delegate library has support for EXIF but we found it to be buggy. It often caused faults and exposed a security vector. We eventually disabled EXIF. Until we see improved support for EXIF in the TIFF delegate library, you will instead need to rely on post EXIF tools to copy, edit, or inject EXIF data.
