Fun at the Aero Museum in Calgary.
I ended up using 4 speedlites on manual settings. One large overhead softbox to fill in the front directionaly. Then one bare speedlite on either side of the group to give it some hard raking side-light. Then one single speedlite tucked in behind the aircraft to light up the canopy.
Full group setup with large kit in the outside hangar - very cold that night.
I love it when a client wants to do something different and we get to come away with more than just the standard stuff. Looking forward to more of this in 2017.
