my guess is rotate the image counterclockwise so that the shiny panels currently on the top of the image are on the left and the bar lights are on the right. My theory here is the light fitting is the only giveway, those things are usually high up and that would put it in normal place. :?:
This would make the place a narrow corridor of some kind.
The easy way to explain the location is to correctly orientate the image and zoom in to reveal the two people...
Picture quality not so good of course, but not TOO bad for 1/40th of a sec
So...all revealed?
