ExifTool truncates ASCII MakerNote data

ExifTool can be used to output a specific Exif MakerNote from your images’ metadata by using the following command:

exiftool -u -Unknown_0x0013 image.jpg

This will output makernote Id 0x13, however if the makernote that you are interested is long, then ExifTool may truncate it and output only the start with […] at the end!

Unknown 0x0013                  : {"distortion":{"factory":{"version":"1.0","medium":"air[...]

To have ExifTool output the full makernote, use the -b (binary) option like this:

exiftool -u -b -Unknown_0x0013 image.jpg
