Trying to overpower the sun seems to have become a popular thing again lately. The go-to technique for these results is a fast shutter speed and high speed sync. But the limited power available in speedlights often falls a little short. Now, with more powerful HSS-capable strobes on the market, like the Godox AD360II and AD600BM, it’s become a more common look.
This look has been available for a long time, though, with the use of neutral density. These would allow you to shoot wide apertures in the daytime while keeping your shutter speed below the flash sync. In this video from photographer Levy Moroshan of sector5films we see how that technique works. Balancing the bright daylight with the flash, to make our subjects stand out with a shallow depth of field.
