4.3 Flash Modes
The TT350S supports several flash modes to suit different shooting requirements:
- TTL (Through-The-Lens) Mode: The flash output is automatically adjusted by the camera's metering system for optimal exposure.
- Manual (M) Mode: Allows manual control over flash power output from 1/1 to 1/128, with 22 levels of fine adjustment.
- Multi (Stroboscopic) Mode: Fires a series of rapid flashes during a single exposure to capture multiple movements of a subject.
- S1/S2 Optical Slave Mode: Triggers the flash optically when another flash fires. S1 fires on the first flash, S2 ignores the pre-flash of a TTL system.

4.4 Synchronization Functions
- High-Speed Sync (HSS): Enables flash synchronization at shutter speeds up to 1/8000s, allowing for wider apertures in bright conditions or freezing fast motion.
- Front-Curtain Sync: The flash fires immediately after the shutter opens.
- Rear-Curtain Sync: The flash fires just before the shutter closes, creating a trail of light behind moving subjects.
- Flash Exposure Compensation (FEC): Adjusts the flash output to fine-tune exposure.
