I've been playing around with this a bit more, and have added some preliminary code to provide read/write support for the PhotoStation trailer. It still needs some testing, but I have uploaded a 6.51 pre-release with these changes for you to play with if you want.

I have decoded a bit more information since my last post, but I was wrong about the crop position being in inches (I haven't figured out what units these coordinates are in yet). You can use the -U option to see unknown tags in the crop information, and the -v3 option to dump the FotoStation trailer records in hex.

I'll let you know if I discover anything else.
