Wonderful photos and superb report. Can I ask what camera and lense(s) you used? A DSLR presumably?
I just snapped a very hasty TR on an iPhone on a recent trip and it's obviously impossible to get any depth of field on that without resorting to effects. I have Canon 5D MkII and a bunch of lenses but it is so conspicuous that I somehow wouldn't dream of using it in an airport or on an aircraft.
