This is very cool (and, amazingly, I've gotten it to work form me.) I'm still trying to figure out how to run the perl script, but I'm happy I at least have the commands working on the command line!
Any way, I'm curious, does this script produce essentially the same results as if you output differently exposed tiffs converted from a RAW file, or would that technique offer a slightly better result? I ask out of curiosity (I don't normally have access to a camera that shoots RAW.)
