flash

In photography, when you're trying to add flash and want it 'off-camera' there's a few options. Off-camera flash is important, because let's be honest, on-camera flash looks harsh and just plain bad. So we have to move the flash away from the camera. Sometimes it's to the right, sometimes left, sometimes up. Other times you might add more than one flash to light the frame.

One way is to use a sync cable. This involves the possibility of adapters, and stretching a long cable between you and the flash. My camera doesn't have a sync socket, so I'd need an adapter.

Another way is to use an optical flash. This is a flash that is triggered any time it sees any other flash light up the scene. I have one of these, and it's great until there's other people in the same area with flash cameras. Then it gets flashed for them instead of me.
