This was shot using a D202 power pack in a rolling cart, and the power was provided by a Tronix Explorer 1200 portable battery and sine wave inverter. A single M90 flash head was elevated about nine feet high, and the light was placed nine paces distant from the model. The M90 has a non-interchangeable, 8.5 inch diameter reflector.
