Evening all,a quick question on flash photography,should the flash fire to every acctuation of the shutter in high speed ?? thanks Brian:thinking:
 
Not sure what you mean there Brian. The flash fires at the beginning (or end) of the exposure. High speed sync flash strobes the flash through the duration of fast (above the sync speed) exposures.

Does that answer your question?
 
Hi Alex,probably does answer the question,but I just thought that the flash would be a rapid fire of flash's like the shutter,it seems that it is so many flash's then it's like the shutter is too fast for it.(hope this makes sense)
 
I think he's asking will the flash will fire on each shot in the continuous drive mode. And the answer is yes, but you will find the continuous speed slows down as the camera needs to recharge the flash.

If the flash needs to be on full power on my 450d its takes a four or five seconds between shots

If the flash is on a lower power its a little faster. But still slower than usual continuous mode.

My camera doesn't miss any shots, it just waits for the flash. Nor sure about Nikons though
 
If you mean in continuous mode, no the flash will not fire every release as the flash will not recycle quick enough, 5-10 frames a second is to much to ask of a flash, you may get 2 or 3 frames, but this is all dependant on how mush light is required.
 
Thanks all for the info,thats whats happening Dave,so you've answered my question,is there no way of getting the flash to fire every time ???external battery pack or will this not be enough???:shrug:

I very much doubt that an external power pack would do what you want. If you do not mind me asking what are you trying to shoot/ achieve.
 
Hi Dave,photographing birds and mammals,but just bought a 580EX and been playing about with it trying differant things and noticed that it did'nt fire all the time so thought it was something I was'nt doing right,it's on a MK11n.So these pro users have the same problem then do they???
