Below you will see a composite from the evening photos. The main shot is the ambient light from the street. Other shots of Mila and the smoke were taken with a Canon Speedlite on a Quantum battery, triggered remotely by an Aputure Trigmaster (more reviews on the device in a future post). The camera is on a tripod while I hand held the flash at different angles pointing at Mila, and my assistant Tiffany would press the camera shutter on my command.
