Three lights at full strength, and one low-power one to bring up detail on the fireplace, in order to pull in the view out the arched window. One light to camera left, aimed at the ceiling, another to camera right, also aimed at the ceiling, both bare-bulb, both 1/1 power. On-camera 430eX w/ diffuser cap, aimed up and more or less at the rear corner of the room. And an old Promaster strobe set at 1/16 and gelled down to 1/32 hidden behind the coffee table, to bring up some detail on the fireplace. more detail
