Hi,
I'm just analyzing my Sony ILCE-7RM3 ARW metadata and stopped at SR2 IFD with Offset, Length and Key entries (7200, 7201 and 7221).
It is a way to extract the decoded content of the SR2SubIFD (pointed by 7200 and 7201) in a binary form, so that I can analyze the data directly?
I don't really understand how the coding mechanism with the key (defined by 7221) works, so the decoded content will be the best!
Any help appreciated!
You can get a hex dump using the ExifTool -v5 option. To get it as binary data you could either convert this hex or hack Sony.pm to add a statement to write the data to file after it is decrypted.
