Strobist: Canon 430ex II from behind a sheet of tracing paper directly behind the glass. It’s set at 1/16th power at 14mm zoom with wide angle diffuser. There are black flags to the left and the right of the tracing paper to prevent spill. A vivitar 285hv at 1/16 power shot over head through a softbox. White posterboard under the glass to reflect light back up to the glass.
