Subject: [Leica] M9 gotcha

This weekend I learned, the hard way, that if you ask an M9 to produce 
compressed DNG files it only keeps 8 bits per pixel. If you want the full 14 
bits per pixel that the sensor records you have to store uncompressed DNG.

I didn't read the documentation as closely as i should have. Not that the 
documentation is explicit about this. On page 174 of the English-language 
manual it says that DNG compression is achieved "by non?linear reduction of 
color depth".

Foo. Next time I'll get this right.
