Not a .dng, just an unzipped form if itself.

I have to believe a compressed .raf uses some form of rar or zip algorithm. And as it’s lossless there must be a way to unzip it.

Presumably so - but its not the entire file that is compressed - just the CFA raw data within the file - that complicates things a bit

That makes sense.  The camera writes out the header portion of the file then engages the compression on the  cfa data since the compression method is (likely) tweaked to work only with the cfa data anyway.

And I’m thinking the compression can’t be too complicated because the camera has to do this all in real time.
