Hello,

I would like to know if it is possible to modify raw data or generate completely fake raw files with LibRaw?
If not can someone please point me in the right direction?

I searched intensively but have no luck with finding any information about generating NEF files or DNG files from scratch. Alternatively it would probably suffice just to somehow overwrite the image data contained in the NEF raw file.

Any ideas on how to do this?
I'm not a real developer I just write python most of the time.
