Ensure that the flash you have, or are thinking about purchasing has high speed sync capabilities! Examples of this high speed sync can be seen in sports photography where a soccer player is frozen in motion just before the foot reaches the ball, or in water droplet photography where the motion of water is stopped as an ice cube breaches the surface. Most basic flashes auto sync with the camera at EV’s of 1/200th to 1/250th, but in FP, or full power mode, the flash can sync with the camera at extremely fast shutter speeds.
In TTL mode your camera will communicate its current settings (f/stop, ISO, focal length, Exposure value) with your flash so that it can use the correct amount of power to light the scene. The flash is of utmost importance, ensure that your flash can shoot in Full Power TTL. This allows me to work in TTL Auto FP with the ability to mobilize the flash with my free hand to my liking.

I am pretty excited to see the bottom of this post, so let’s get down into this! I have been experimenting a lot lately with speed light macro photography and I can easily say, I am loving it! Once you get the basics down and start popping off shots, it feels like every one of them is a money maker.
