• TTL (Through-The-Lens): Automatic flash output based on camera's metering.
• M (Manual): Manually set flash output from 1/128 to 1/1 power.
• Multi (Stroboscopic): Fires a series of rapid flashes for multiple exposures in one frame.
• Master: Controls other slave flash units wirelessly.
• Slave (S1/S2): Triggered by another flash. S1 is optical slave, S2 ignores pre-flash.
• FEB (Flash Exposure Bracketing): Takes three photos with different flash exposures.

3. High-Speed Sync (HSS)

The NW870 supports High-Speed Sync up to 1/8000s, allowing you to use flash at shutter speeds faster than your camera's native sync speed. This is useful for overpowering ambient light or using wide apertures in bright conditions.

4. Wireless Triggering

The flash supports wireless triggering via light pulse or induction flash. It has 4 channels (1, 2, 3, 4) and 3 slave groups (A, B, C) for complex lighting setups. Wireless flash distance is 20-30m indoors and 10-15m outdoors.

5. Flash Head Rotation

The flash head can be rotated vertically from -7 to 90 degrees and horizontally from 0 to 180 degrees, allowing for bounce flash and flexible lighting angles.

6. Using Color Filters and Diffusers

The kit includes 20 color filters and hard/soft diffusers to modify the light quality.

• Color Filters: The 20-piece set includes 14 color effects, 5 color correction, and 1 diffusion filter. They attach quickly to the flash head using their tabbed design. Use them to add creative color to your lighting or correct color temperature.
• Soft Flash Diffuser: Spreads and softens the light, reducing harsh shadows and creating a more natural look. Simply slide it over the flash head.
• Hard Flash Diffuser: Reduces harsh shadows and eliminates red-eye effect, making the light more balanced. Attaches similarly to the soft diffuser.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the flash unit. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the unit. Do not use solvents or abrasive cleaners.
• Storage: When not in use for extended periods, remove the battery from the flash unit. Store the flash and accessories in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided protective bag for storage.
• Battery Care: Recharge the Li-ion battery regularly, even if not in use, to maintain its lifespan. Avoid fully discharging the battery frequently.
