I’m intermittently working on adding data from other projects to my github repo, GitHub - butcherg/ssf-data: Spectral sensitivity data for digital cameras. For this camera, Nikon D750, I have SSF data from the OpenFilmTools eneavor but I haven’t worked out the license to add the data itself to the repo. So, I just made the ICC profile from it and am uploading that here:
Nikon_D750_dcamprof.icc (212.5 KB)
Appropriate credit to OpenFilmTools is in the ICC desc tag.
