What if the flash of hot boots falls into the water?

Dry naturally or with a hair dryer. Hot shoe flash is a kind of flash, which is mainly installed on the top of the camera. When the hot shoe flash falls into the water, it can't be used any more. Let the flash dry naturally, and it can only be used normally after it is drained of water. You can also use a hair dryer to dry it, which can speed up the drying speed and avoid being connected to electricity or burned out.
