Hey, Clare, it's great to hear from you ! ! ! ! Thanks for stopping by this thread !
Although, like you, I thought that some of the people would fit perfectly in a Zombie walk, Chris and Sam were correct -- it was a large mass casualty / disaster drill at Dulles International Airport -- but, those two guys had insider information. Chris, in the army, and, as I recall, Sam was either a FF or a Paramedic for many years.
We had personnel and their equipment responding from within a 40 or 50 mile radius including fire, emergency medical and LEAs. There was somewhat more confusion than I would have liked to have seen, but I guess that's the whole purpose of such drills.
Anyway, here are a few photos ...
1. We had one of the main runways and associated taxiways blocked off for us for the entire day.
2. Engines and other emergency vehicles were staged in a holding area a km or so away from the crash site and called in as needed.
3. The volunteer "victims" were made up and staged near the site of the simulated disaster.
4. The victims were triaged, stabilized, and then transported to any of several nearby hospitals, as well as an on-site simulated hospital.
5. The next ambulance crew in line is ready to transport the next victim(s).
6. My unit was assigned two ambulatory victims. The woman played her part very well.
7. After the drill, we were treated to lunch by our hosts and had a chance to tour some of the large specialized vehicles used by the airport FD.
8. An example of a "black box" from a real crash was available for training purposes.
With respect to technical photographic issues, the main challenges were the very, very deep shadows and the fact that there was absolutely no way to reposition the subjects to try to minimize these. So, to provide fill light, one of my strongest flashes stayed on the camera for essentially the entire day, and I used the tonal adjustment sliders in Lightroom to either further minimize shadows and/or provide a more natural look. I think that the only image in this set that I took into Photoshop was #63, the foam vehicle. The shadows were just about impenetrable, and since I was limited to on-camera flash, I couldn't use fill flash because it would have brightened up the front of the vehicle much more than the rear. So, I turned off the flash for this one. After a first pass at brightening the shadows in LR, I used the much better selection tools available in PS to further brighten the shadow areas.
Everyone learned a lot and a good day was had by all.
