bismarck,
u will need to keep ur shutter open for longer than that.. 1.3
seconds? eheh well if that's the longest u can go for, then use
that setting.
as for ur iso and aperture, it's hard to tell. typically u won't
really blow out fireworks since it's pretty instant. still, a mid
range aperture would be safer (f5.6?), and plus u don't wanna over
expose the stadium on the ground. iso200 to keep the noise levels
down.
btw.. ur cam can choose aperture settings meh?
alamak actually aitaiyuan should ans ur questions.. he's the one
that's taken so many fireworks shots!!
