How does a slave flash work?

Slave flashes are simply self-contained flash units which respond to external triggers of some kind. They’re frequently used in studio situations. For example, you might have a multiple-flash setup – one flash to illuminate the subject and another unit or two to illuminate the background separately.

What triggers the slave camera?

The only additional feature on them is that they can be triggered by firing another flash, i.e., optically without the need for a radio trigger or PC sync cord. All slave flashes come with a sensor in them which senses the light fired out of another flash. That in itself triggers it to fire the light.

What is guide number for camera flash?

For any given “correct flash exposure” situation, guide number is simply numerically equal to the aperture number (like the number 8 in f/8) multiplied by the subject distance (like 10 feet). Then for example, the guide number is f/8 x 10 feet = GN 80 (feet units).

Can you use a speedlight off-camera?

The cheapest and most reliable way to fire your speedlights off-camera is by using a sync cord — basically, you connect your speedlight to your camera via a long cable. The drawbacks of using a cable are that it reduces the distance you can be away from your flash, and it can create a tripping hazard.
