How to use water droplets to make mobile phones shoot macro?

Of course, you can use a flash, or even it is better to shoot water droplets with a flash. Because shooting water droplets requires a high shutter speed to solidify the moment when the water droplets fall, and the indoor light is dark, the shutter speed is generally not enough if a flash is not used. Moreover, it is best to use an external flash. On the one hand, the high-speed synchronization function can be used to make the shutter speed exceed 1/200 seconds when the flash is turned on, which is more conducive to capturing the moment; On the other hand, the light distribution of the external flash is more flexible. When shooting, put the camera on a tripod, use manual focusing, aim at the place where the water drops fall, don't worry, try to focus accurately. Then set the flash, you can consider putting the flash in the position of the side backlight, which makes it easier to show the feeling of crystal clear water droplets.
