Are you referring to an optical slave?

If so, they are small electrical devices that are connected to a flash unit via a sync cord or a hotshoe adapter.

There fire the connected flash, when they "see" a flash from another flash source.

They are inexpensive and reliable.

They allow you to place a flash in a position and fire it without any connecting cord.

There are other types of slaves such as radio slaves.

Most current studio flash units have built in optical slaves as do a few hotshoe based flash units like the Sigma Super.

But, optical slaves do not easily work with recent Canon Speedlights.

Enjoy! Lon

Right, i think i understand.
cheers.

i'm a music photographer and im not usually allowed to use flash so i dont understand it that well .

so what is a radio slave? something that sends a radio signal off your camera hotshoe to fire an off camera flash?

yes... a radio slave like the Pocket Wizards will send a signal from a transmitter to a reciever and fire your "Slave" flash... I use two hotshoe flashes fired by Pocket Wizard "Trans-cievers" ( reciever / transcievers all in one) from my 30D... works like a charm but kinda pricey.. Optical slave triggers or Optical triggers do the same but vie infrared.. hence they need a "Line of sight" to work properly. A slave flash is one that ISNT the main flash on the camera, its usually because its told what to do.

Right, now i can saftly say i understand.
Cheers for the help guys.

I have 3 adorama slave flashes, If I want to fire them with my xti, I have to have a radio slave. Is that correct?

It all depends on what the flash is, if its optical slave and it will "read" your on camera flash...no.

Im using "pocket Wizards" they are prolly the best Radio Triggers out there...also the most expensive. They are the "Trans-ciever" ones,meaning, it doesnt matter which one you put on the flash, or the camera, it will automatically know wether it needs to transmit the signal to fire the flash or to recieve it. They still sell the older modles that one is a reciever only and the other a transmitter. You can fire your strobes many ways.... get radio triggers, get optical triggers, get a hotshoe to PC adapter that will sit on your cameras hotshoe and let you plug a PC cable into it to run the flashes ( if you dont mind dragging wires around your feet) or buy some canon 430 or 580 or 550 EX flashes and either use em with the canon transmitter or set one to master and the other to slave.

Thanks Zacker,
Thank you very much for the explaination. Now, the light in my head is getting lighter a little bit. hihi. The world of photography is so lagre, there are a lot of things I have to learn. How much for your trans-receives? and what the name it is? I want to learn about that product.

Hello Zacker,
