Title: Should I use exiftool to batch convert files to Big Endian ?
Post by: Tr on May 09, 2014, 11:03:37 AM
Reading previous posts (https://exiftool.org/forum/index.php?topic=3539.0)
and the FAQ #20, there seems to be some hesitation using exiftool to perform this task:

exiftool -all= -tagsfromfile test.jpg -all:all -unsafe -exifbyteorder=big-endian test.jpg

I believe photoshop has a scripting ability to do this.

Which do you recommend?

Thanks,
Tr

The hesitation is because the byte ordering of the maker note information (and any other proprietary information) can not be reliably changed.

ExifTool will preserve the original byte ordering of the maker notes, but the inconsistency in byte ordering may break things for other utilities which normally would extract this information.

Photoshop is not the solution.  It simply deletes the maker notes entirely.
