High- speed sync flash is particularly convenient when using aperture priority to fill flash for portraits. Short press the function button [SYNC] to turn  on or off the high-speed synchronization function. After the high-speed synchronization is turned on, the LCD screen will display the high-speed synchronization icon.
   When this product is used as a slave unit, the flash synchronization mode needs to be set by the master control unit.

2. Rear-curtain Sync
   When the rear-curtain sync is turned on, the flash will fire at the moment when the shutter is about to close. Using a slow shutter speed and rear-curtain sync can create smear for the subject. The rear-curtain sync function needs to be set from the camera, please refer to the camera manual for the method.

3. Remote Wireless Flash YN685EX-RF supports remote wireless flash: 2.4GHz radio wireless flash shooting (602/603 wireless flash system) has an effective flashing distance of up to 100m; For optical transmission wireless flash shooting (Ss/S1/S2),the longest distance for indoor use can reach to 25m, and the longest distance for outdoor use can reach to 15m. Please refer to the “Wireless Flash Shooting” chapter for detailed setting methods.

4. Flash Exposure Compensation
   To make the shooting effect better meet your needs, you can set flash exposure compensation through the camera menu or flash setting. The exposure compensation value setting range on the flash is -3EV ～ +3EV, and the exposure level increment is 1/3EV. Short press the function button [+/-] of the flash to enter the exposure compensation setting state, rotate the [dial] to adjust the exposure compensation value, and press the [SET] button to save the setting.

5. FEL/AEL lock

To use this function, you should lock the center of camera’ s viewfinder at the subject which needs flash exposure, press the flash exposure lock [FEL/AEL] button of the camera, the flash will emit a pre-flash, and the camera will calculate the appropriate flash output data. You have a period of time to recompose the picture, you can press the shutter to shoot after composing the picture (this function needs to be supported by your camera itself, please refer to your camera manual for setting).

6. High-speed Continuous Shooting

This product supports high-speed continuous shooting function, please set the camera to continuous shooting mode, and then shoot.
The quantity of photos of burst shooting depends on the flash output setting. Please use battery with sufficient power.

7. Bounce Flash
   Bounce flash refers to shooting by pointing the 「Flash head」 at the wall or ceiling, and illuminating the object with the light reflected from the wall or ceiling (commonly known as “jumping flash”)， which can reduce the shadow behind the subject and obtain a more natural light effect.
   If the wall or ceiling is too far away, the bounce flash may be too weak and cause underexposure. The wall or ceiling should be flat and white ,which helps to get efficient reflection, if the reflecting surface is not white, color cast may appear on the photo.

8. Use [Catchlight Panel] for shooting
   Use the ‘Catchlight Panel’ to flash, pull the‘ Catchlight Panel’ and ‘Wide Panel’ out of the flash head together, and push the ‘Wide Pane l’back.
   If you shoot at this time, you can create high light points in the model’s eyes, making the eyes more charming and beautiful(catchlight). This function can achieve the best effect when you position the flash head toward the front and 90°up.

9. Use Wide Panel
   Pull out the ‘Wide Panel’ and push back to the ‘Catchlight Panel’ , and place it as shown in the figure. The flash range will be expanded and the flash effect will be softer and more natural.
   When using the ‘Wide Panel’ , the flash coverage will be expanded and locked to 14mm.
