Dark background is very important, or you can underexpose the background. 



This is ( http://evrimgallery.com/Proofs/JacquelineM/jacq_2_023s.jpg ) one
that worked a little better than another one, in which it was very dim
bulding, but i was using 1hz (1 flash every second), and even at f22, the
background registered. Also, the GN drops radically with this approach, and
with a high f number, even more so.
