[FFmpeg-user] How do I prevent this FFmpeg from removing the Exif metadata?

Hi

How do I prevent this FFmpeg from removing the EXIF metadata?
It|'s a single frame image||.|

|ffmpeg -i "Input.JPG" -vf scale=iw*.5:-1 -update true "Output.jpg"|

I tried combinations of |-movflags use_metadata_tags| and |-map_metadata 
0| but with no success.
Maybe I'm not implementing the command correctly?

Thanks in advance
