Right now the initial hot industrial application for NeRF's are recovering radiance fields from ordinary video footage. You can have someone just walk around with an ordinary camera or phone, just making sure they have decent coverage. Then back in the studio after a bunch of crunching you get a 3d virtual set you can position a camera in arbitrarily. The quality of this is considerably better than previous approaches that were based on recovering 3d meshes. The work in the original post can now extend that process to capturing HDR data, which should enable better quality when compositing with other footage or rendered elements. And you don't need some special HDR video camera, just an ordinary one can sample the same thing.
