4. Иштөө режимдери
4.1 TTL (Through-The-Lens) Mode
In TTL mode, the flash automatically adjusts its output based on the camera's metering system, providing accurate exposure for various lighting conditions. This mode is ideal for quick shooting and situations where lighting changes frequently.
4.2 HSS (High-Speed Sync) Mode
High-Speed Sync allows the flash to synchronize with shutter speeds up to 1/8000s. This is particularly useful for shooting with wide apertures in bright conditions or for freezing fast motion, as it allows for a perfect exposure even with high shutter speeds.

4.3 Optical Slave Control (S1 & S2 Modes)
The NW645II-N can function as an optical slave unit, triggered by another master flash. It is compatible with original master flash units and can be activated when set on the same channel and group.
- S1 режими: The flash triggers when the master unit is in manual flash mode.
- S2 режими: The flash triggers when the master unit is in TTL flash mode, ignoring the pre-flash.

4.4 Rear Curtain Sync
Rear curtain sync fires the flash at the end of the exposure, just before the second curtain closes. This technique is used to create a streaking effect behind a moving subject, while the subject itself remains sharply frozen by the flash.

4.5 Manual Output Adjustment
Flash output can be manually adjusted from 1/1 (full power) to 1/128 in 1/3 stop increments. This allows for precise control over the flash intensity to match specific ambient light conditions and creative requirements.

5. Өзгөчөлүктөрү
5.1 Flexible Bounce Angles
The flash head offers extensive articulation, allowing it to swivel up and down between -7° and 90°, and rotate 270°. This flexibility enables you to bounce light off walls or ceilings, creating softer, more natural illumination with reduced harsh shadows.
5.2 Built-in Diffusers and Reflector
The NW645II-N includes a built-in reflective board and a wide-angle diffuser. These accessories help to broaden the flash output and soften the light, which is beneficial for portrait photography to create more pleasing catchlights and reduce harshness.
