thanks. I try it out. Without flash, my shutter is bout 1/30, with 580ex2 my shutter is 1/60. This is in av mode. I had already set my iso highest, and aperture widest at f2.8.
I go shaky hands. Anyway to achieve faster shutter speed? I tried tv mode. I can set the speed to 1/200, but when i focus, the f2.8 is blinking. Any issues with that. When i low the shutter back to 1/30, the f2.8 stops blinking.
ooh, din see this...
ok, just to add on, like i say before, most camera default will use 1/60 unless you press AEL or use rear sync, or manual mode.
the truth about this thing is, if you have got shaky hands, then use a tripod. nuff said.
When the f2.8 start blinking means it goes beyond it's range... for eg, its suppose to use f1.4 but your lens is max f2.8, so its telling you there will be error.
From what i think now, i guess you are shooting in complete darkness or the background is very dark, and your exp comp is either 0 or +1, cos its iso1600 with a f2.8 setting giving 1/30... but if i was shooting, i might even go 1/4... if my lens have IS/VR or body have stabiliser.
To let you know your work about... damnit late for work, wat the heck...
Just to give you a better idea...
you should illuminate the background, if you have a light meter or maybe just use your camera's, like now, it shows, f2.8 1/30 iso1600. you take a shot, you see if the background is nicely illuminated... if it is, good... next step.
now to lightup your subject. using the same setting before, you dun use the normal flash sync, instead, use rear sync flash, esp for any speed lower than 1/60, y? cos if you use front sync (forgot the name, since not rear, must be front), you will get your subject over exposed (most of the time), cos your flash goes pop 1st and then it wait for 1/30 or more to close shutter, instead, we should illuminate the background, meaning, shutter open, expose background, flash pop, illuminate the subject, then close, this is especially good if your subject tends to move.
anyway, try it and you will know what i mean...
