I even tried adding -define tiff:exif-properties=true, but I suspect that define is really when reading tif files.

ImageMagick relies on the libtiff delegate library to read and write TIFF images. The TIFF delegate library can read EXIF tags but cannot reliably write them. Try exiftool to write a EXIF profile to a TIFF image.

Curious what you mean by "reliably" write them. Does that mean it sometimes does?

What we mean is that there were some attempts by the TIFF developers to support EXIF and they decided against completing the implementation suggesting it was a "rabbit hole." In previous versions of ImageMagick, we tried to support EXIF ourselves but we did not have much success so we abandoned the effort.

Thanks for the clarification.
