Leica M Monochrom (Type 246) raw file (DNG) analysis
As usual when new Leica cameras come out, I took a quick look inside a DNG from one of Leica's new Leica M Monochrom (Type 246) cameras:
The camera is using what appears to be production software - version 1.0.0.4. The camera name shows as "LEICA M MONOCHROM (Typ 246)" The image data is 12-bit. There is no compression used in the DNG I looked at. The data is packed, four 12-bit values in 6 bytes, as is the case for the Leica T. The DNG version is 1.3, with a "backward version" of 1.1. There is nothing in the file that goes beyond the DNG 1.1 specifications; no opcodes, etc. The DNG is encoded as "LinearRaw" ("PhotometricInterpretation: LinearRaw"), as was the original Monochrom. The way the DNG spec works, you can either set that to CFA (aka a Bayer array type camera) or to LinearRaw.
