changing the model ID is not a one-liner, sorry. (use a hex-editor) It's the tag id's 110 (hexoffset 5e) and C614 (hexoffset 106) - it writes its string-length and the string offset into the tag-data. i dont know if i wrote the string on the end of the metadata, possibly the length of the string changes the offset of forthcoming data - makes following entries illegal/defective.
so, i tried to write a more stable and better version to christmas (you've seen the 1.4.9

but the time before christmas is full of familiy-action. give me some days after newyear to stabilize raw2cdng.
toDo for the next version.
* stable read and write with mutlithreading (had a chat with g3gg0 about it)
* dng-header generation - modul rewrite
* IliasG's new LUT for 10bit/log (will work for older bodies with blacklevel 1023 as well)
* 12bit/log with bmcc like data (hopefully we're coming to an lovely workflow with premiere)
as is mentioned before, Resolve 10 is no longer a problem, so i dont want to "improve" any things there. speedgrade is working as well - but premiere and the dynamiclink-workflow lacks of being consistent/stable .
(happy new year - and: magiclantern rocked this year, so all my technical love goes to the ml-crew that made this happen)
