My quite recent test showed than there is almost nil difference between
the GN at the open (at night, zero ambient light) and inside an ordinary
white_walled room. Within 1/3 f-stop.
BTW, it also revealed that (by definition?) all flashes have less GN
than advertised and that only good_quality cells are capable of feeding
the flash to it's maximum output.
