Need some enlightenment for a total photography noob here on the use of flash.
I was trying out the 430EX flash few days back to do some casual shoots at a personal indoor event. I realised that when I try to take pix continously, one after another, in short time intervals (need not be immediately), some of my shots will turn out to be underexposed (dark).
Is it that the flash cannot charge up in time?
Is there any settings that I'll need to set on the flash/camera to avoid this again?
Does the type of batteries I use have any effect too?
can the CS gurus advice?
