Are you serious about #photography on #Linux ?
Then you probably used #code derived from #dcraw . It's an amazing store of information about developing raw pictures.
But there's one problem.
It's write-only code. My mind goes blank when I read it.
Thankfully, someone started a readable library for raw files, called #libopenraw :

I ported Panasonic #decompression and made it possible to understand :D
(#Fedora plz package it)
