how does a slave flash work?
hallo newsgroup,
i'm quite new to photography so i just hope these questions are not too stupid :-P take an slr camera where it's possible to attach a flash to it. there are special contacts on top of the camera for plugging it, and through those contacts the flash can synchronize itself with the camera, so it actually enlights the space at the right moment (i.e. when we shoot the picture). but then take a so-called "slave" flash: it plugs _under_ the camera, on the same plug we use for the tripod. how can it synchronize the light with the moment you actually shoot the picture? i hope you can explain this to me :) by the way, i don't like the enbodied flash of my camera (eos 300), would you suggest me to take a slave flash or a regular flash to be plugged on top of the camera? i also knew that a decentralized flash would avoid the nasty red-eye effect, so i thought a slave flash would be a good idea... again, can you guide me through this decision? :) thanx in advance francesco |
