Hum... ok I think I figured out a way to do it in camera...
but it would involve things like:
1. very very very careful positioning
2. probably cropping some of the frame, though I'm not sure that would ALWAYS be necessary
3. owning a tilt-shift lens
I suppose a 45 TSE shot at F11 or thereabouts with the right amount of tilt (and maybe shift to get yourself out of the shot... though I'm not sure that's really an issue) ... could get this baby done in one shot.
One lucky lucky lucky, skillful shot... at least based on my experience with T/S (then again there's live view now)...
and I think it's more likely to work for the cityscape photos than for the Davina+Daniel shot due to the shooting on a rooftop tilted plane of focus running into the city below... but maybe not, maybe it works even in the volcano shot.
Whether this is an answer or not, there's a lesson inside... it can't hurt to try out some of our lenses at apertures narrower than 2.8 sometime
