Flash Mode — E-TTL Auto Flash
In ETTL mode, the camera’s metering system detects the flash reflected from the subject and automatically adjusts the flash output so that the subject and background are evenly exposed. In this mode, multiple functions are available: FEC, FEB, FEL, HSS, second curtain sync, etc.
Press < MODE > mode button to enter ETTL mode, the LCD panel will display <ETTL>.
Press the camera shutter halfway to focus. The aperture value and effective flash range will be displayed in the LCD panel.
When the shutter is fully pressed, the flash will fire a pre-flash that the camera will use to calculate exposure and flash output the instant before the photo is taken.
FEC (Flash Exposure Compensation)
With FEC function, this flash can adjust from -3 to +3 with 1/3 increment each step. It is useful in situations where minor adjustment of the TTL system is needed based on the environment. Setting FEC Amount 1. Press the <+/-> button, the < > icon and FEC amount will be highlighted on the LCD panel.
2. Turn the select dial to set the FEC amount.”0.3″means 1/3 step, “0.7”means 2/3 step.To cancel the FEC, set the amount to “0”.

3. Press set button again to confirm the setting.
FEB (Flash Exposure Bracketing)
FEB refers to the flash will automatically change the flash output for each shot from -3 to +3 with 1/3 increment each step. With this function, the camera will record three images with different exposures: one exposed according to camera calculations, one over-exposed and another under-exposed. This function helps get correct exposure especially in shooting moving objects or when environmental lights are complex. Setting FEB Amount 1. Press function button 3 <FEB>. The < > icon and the FEB amount will be highlighted on the LCD panel.

Aim the subject at the center of the viewfinder and press <FEL> button. The camera flash will fire a pre-flash and the required flash output for the subject is retained in memory. The “FEL” will be displayed in the viewfinder for 0.5s. The camera flash will fire a pre-flash and the new flash exposure settings is locked every time the <FEL> button is pressed down.
Note1. If the subject is too far away and underexposure, the < > icon will blink in the viewfinder. Please get closer to the subject and try the FEL again. 2. If <ETTL> is not displayed on the LCD panel, FEL cannot be set. 3. If the subject is too small, FEL might not be very effective.
High-Speed Sync
High speed sync (FP flash) enables the flash to synchronize with all camera shutter speeds. This is convenient when you want to use aperture priority for fill-flash portraits.
1. Press function button 2<SYNC> so that the < > icon is displayed on the LCD panel.

1. Press <MODE> mode button so that <Multi> is displayed on the LCD panel.
2. Press the function button 2 <Times> to select the number of flashes. Turn the select dial to set the number, then press it to confirm the settings. Press the function button 3 <Hz> to select the flash frequency. Turn the select dial to set the frequency, then press it to confirm the settings.
38

3. Press <+/-> button to select flash output amount. Turn the select dial to set the amount, then press it to confirm the settings. Flash output range: 1/256-1/4.

Calculating the Shutter Speed
During multi flash, the shutter remains open until the firing stops. Use the formula below to calculate the shutter speed and set it with the camera.
Number of Flashes / Flash Frequency = Shutter Speed
For example, if the number of flashes is 10 and the flash frequency is 5Hz, the shutter speed should be at least 2 seconds.
To avoid overheating and deteriorating the flash head, do not use multi flash more than 10 times in succession. After 10 times, allow the camera flash to rest for at least 15 minutes. If you try to use the multi flash more than 10 times in succession, the firing might stop automatically to protect the flash head. If this happens, allow at least 15 minutes’ rest for the camera flash.
Note: 1. Multi flash is most effective with a highly reflective subject against a dark background. 2. Using a tripod and TTL flash trigger XPROII is recommended. 3. A flash output of 1/1 and 1/2 cannot be set for multi flash. 4. Multi flash can also be used with”buLb”mode. 5. Multi flash mode cannot be set in high-speed sync mode. 6. If the number of flashes is displayed as “–“, the firing will continue until the shutter closes or the battery is exhausted. The number of flashes will be limited as shown by the following table.

Wireless Flash Shooting: 2.4G Wireless Transmission
This section explains wireless transmitting/receiving flash shooting. The V1Pro C attached to the camera is referred as the transmitter unit, while a V1Pro C that is wirelessly controlled is referred as the receiver unit. You can also wirelessly control the V1Pro C set as the receiver unit with the TTL flash trigger XPROII (sold separately). For details on setting the flash trigger functions, see the its instruction manual.
NoteWhen the camera’s shooting mode is set to a fully automatic mode or an image zone mode, the operations in this section are not available. Please set the camera’s shooting mode to Fv/P/Tv/Av/M/B.
Using a flash with a radio transmission wireless shooting function make it easy to shoot with advanced wireless multiple flash shooting, in the same way as E-TTL II auto flash shooting. As long as the channel, group, ID, and other relevant wireless settings of the transmitter and receiver units are set to the same, the settings on the V1Pro C (transmitter unit) will be automatically applied to the wirelessly controlled V1Pro C (receiver unit). Therefore, there is no need to operate the receiver unit during shooting.
Positioning and Operation Range (Example of wireless flash shooting)
Auto Flash Shooting with One Receiver Unit
Transmission distance is about 100m
Note1. Before shooting, perform a test flash and test shooting. 2. The transmission distance might be shorter depending on the conditions such as positioning of receiver units, the surrounding environment and whether conditions.
Auto Flash Shooting with Multiple Receiver Groups You can divide the receiver units into two or three groups and perform E-TTL II auto flash while changing the flash ratio (flash output ratio). In addition, you can set and shoot with a different flash mode for each firing group, for up to 4 groups.

The Reason & Solution of Not Triggering in Godox 2.4G Wireless
1. Disturbed by the 2.4G signal in outer environment (e.g. wireless base station, 2.4G wifi router, Bluetooth, etc.) To adjust the channel CH setting on the flash trigger (add 10+ channels) and use the channel which is not disturbed. Or turn off the other 2.4G equipment in working.
2. Please make sure that whether the flash has finished its recycle or caught up with the continuous shooting speed or not (the flash ready indicator is lightened) and the flash is not under the state of over-heat protection or other abnormal situations. Please downgrade the flash power output. If the flash is in TTL mode, please try to change it to M mode (a pre-flash is needed in TTL mode).
3. Whether the distance between the flash trigger and the flash is too close or not ( 0.5m). Please turn on the “close distance wireless mode”: X1 Series: Press and hold the triggering button then turn on the device until the indicator blinks twice. Xpro and X2T Series: Set the C.Fn-DIST to 0-30m. X3 Series: Set the trigger distance to 0-30m.

Other Applications
Sync Triggering
The sync cord jack is a 2.5mm plug. Insert a trigger plug here and the flash will be fired synchronously with the camera shutter.
Modeling Flash
If the camera has a depth-of-field preview button, pressing it will fire the flash continuously for 1 second. This is called modeling flash. It enables you to see the shadow effects on the subject and the lighting balance. You can fire the modeling flash during wireless or normal flash shooting.
Note1. To avoid overheating and deteriorating the flash head, do not fire the modeling flash for more than 10 consecutive times. If you fire the modeling flash 10 consecutive times, allow at least 10 minutes’ break for the camera flash. 2. The modeling flash cannot be fired with the EOS 300 and Type-B cameras.

Auto Focus Assist Beam
In poorly-lit or low-contrast shooting environments, the built-in auto focus assist beam will automatically light on to make it easier for autofocus. The beam will light up only when autofocus is difficult and get out as soon as the autofocus becomes correct.
If you want to turn off the auto focus assist beam, set the “AF” to “OFF” in the C.Fn settings.
NoteIf you find the auto focus assist beam does not light up, this is because the camera has got a correct autofocus.

Position Center Periphery

Effective Range 0.6~10m / 2.0~32.8 feet 0.6~5m / 2.0~16.4 feet

Bounce Flash
By pointing the flash head toward a wall or ceiling, the flash will bounce off the surface before illuminating the subject. This can soften shadows behind the subject for a more natural-looking shot. This is called bounce flash.

330°

-7-120°

To set the bounce direction, hold the flash head and turn it to a satisfying angle.

Note1. If the wall or ceiling is too far away, the bounced flash might be too weak and result in underexposure. 2. The wall or ceiling should be a plain, white color for high reflectance. If the bounce surface is not white, a color cast may appear in the picture.

ZOOM: Setting the Flash Coverage
The flash coverage can be set automatically or manually. It can be set to match the lens focal length from 28mm to 105mm. In auto zoom mode, the focal length changes in response to the camera’s zoom lens to provide optimal flash results.
In manual zoom mode, press the <ZOOM> button.
Turn the select dial to change the flash coverage. If < > is displayed, the flash coverage will be set automatically.
NoteIf you set the flash coverage manually, make sure it covers the lens focal length so that the picture will not have a dark periphery.
