6.1 TTL (Through-The-Lens) Mode
In TTL mode, the flash output is automatically controlled by the camera's metering system to achieve optimal exposure. This is the most convenient mode for general photography.

6.2 Manual (M) Mode
Manual mode allows you to set the flash output power manually from 1/1 (full power) to 1/128 power, with 22 levels of fine tuning. This provides precise control over lighting for consistent results.
This image demonstrates the various flash output levels available in Manual mode, from 1/128 to 1/1 power.
6.3 Multi (Stroboscopic) Mode
In Multi mode, the flash fires multiple times during a single exposure, creating a stroboscopic effect. You can set the number of flashes and the flash frequency.
6.4 Højhastighedssynkronisering (HSS)
The YN568EX III supports High-Speed Sync (HSS), allowing you to use flash at shutter speeds up to 1/8000s. This is useful for freezing fast motion or using wide apertures in bright conditions.
This image illustrates the capability of High-Speed Sync (HSS) to freeze fast-moving subjects, such as water droplets, at shutter speeds up to 1/8000s.
6.5 Wireless Slave Mode
The YN568EX III can function as a wireless slave unit, triggered by other flash units or camera's built-in flash. It supports optical transmission wireless slave modes (S1/S2) and is compatible with Nikon's optical master units (e.g., SB-910, SB-900, SB-800, SB-700, Nikon internal flash). It can also act as a master unit to trigger other YONGNUO and C EX series speedlites (excluding YN585EX) across 4 channels.
