A slave flash is a flash not electrically connected to the camera, and operates by sensing thelight from the camera built in flash.

If a camera has a built in flash, it will work. They are made to enhance the weak built in flash, even if the camera does not have hotshoe or PC terminal to connect a "normal" external flash. Slave flashes made for digital camera even "knows" the camera flash "profile" (one , 2, or more preflashes ...)

So is there certain compatability with flash salves, or does any camera with a flash work ok. What about a very weak flash(DSC T7) , would it still work?

Of course, I can't guarantee that every slave flash will work with every camera. But, there are good chances that some models do. Until someone tried a particular combination, we never know.

Hi

My 10 cents worth. Here is an adaptor I knocked up, it plugs into the 1/4" jack socket of a cheap studio flash, turning it into a slave flash

Hi

Plastic 35mm film cannister, a standard 1/4" jack minus the body, and a simple slave . The LDR is mounted into the cannister lid , The jack plug is mounted into the base of the cannister and araldiited in. Quite simple really, but very effective.

Forgot too mention, the slave is self powered from the flash trigger itself . Depends what voltage the flash is and what voltage the slave requires. You may have too use a potential divider too lower the voltage.
