Thanks for the link, however i'm still not sold on the term. You "generate"
hdr data, not "reconstruct": it's generated/estimated/made up data, not
data that is lost and needs to be reconstrcuted. I suggested "tonemap"
because you're mapping SDR tones (aka colors) to HDR ones, and that seems
the right term to use. If you really dislike it, at least consider "HDR
image generation from a single exposure using deep CNNs" which would work
much better.
