metadata problem

[Alan Clifford]

I recently put open camera onto my mi Xiaomi mi a2 lite and noticed that the camera information did not show up when viewing using nikon viewnx-i on my macbook.
On examination of the metadata with exiftool, the following is shown:

PS.
If your photo also has a color profile which you want to preserve, execute ...
exiftool -all= -tagsfromfile @ -all:all -icc_profile *.jpg

If you actually wanted to delete the metadata, (in this instance, why? <grin>) use ...
exiftool -all= -tagsfromfile @ -all:all -unsafe *.jpg

Finally, if you wanted to remove all the 'unsafe' metadata but retain your color profile ...
exiftool -all= -tagsfromfile @ -all:all -unsafe -icc_profile *.jpg
