I was shooting a conference in Adelaide and the client wanted a group shot of all the delegates. The original plan was to do the shot outside at a nearby park, but time was running short so the request was made to setup a shot as close as possible to the conference room, in 15minutes. The stairs in the foyer was the only practical location and the main problem was that it was so dark. I found a vantage point on  the next level up and set up the speedlights along the balcony to flood the space with a light from the left.
