Thank you, a seriously insightfully comment. It's post as you said and I have thought about using CG trickery for it and super impose a background. It will come up eventually. 2 tries with a 1/400 Shutterspees f. 6.7 I believe with flashes to assist.
It is unusual now that you come to think of it. I don't know however whether it's a good thing or not. In effect you can easily render CGI into it but then it wouldn't be authentic as it would be in the scene it was best placed in I.e. Jecht is best seen on smouldering Rocks and crumbling Blitzball Arenas or Temples... Who on EARTH HAS THAT in their back garden?!
