How to Use Canon Speedlite 430 ex flash

Turn the flash on. Wait for the flash charge to recycle and the red "Ready" light to come on.

Put the Speedlite on the "ETTL" setting to activate fully automatic flash.

To use it as wireless flash, switch the wireless setting to "Slave" and adjust your camera accordingly. Set the right channels and slave IDs before clicking the shutter to avoid any problems.
