as with every other type of photography there's a really easy answer, thats of no use whatsoever.
"the appropriate one"
and without any more information as to what kind of night-time photography you're trying to do, it's all we can offer.
are you looking at light-trails from moving vehicles
are you looking to shoot people portraits outside in the dark, or near dark
do you want to capture fireworks displays
are you wanting to shoot architectural imagery...
all four will need completely different settings, and possibly additional hardware over and above the camera.
