Ask Yongnuo how to use manual flash.

1. when shooting, the automatic metering point of the camera is aimed at the background first, and only the exposure of the background is considered. At this time, the photometric parameters displayed by the camera correspond to the background.

2. At the same time, in the ETTL automatic flash mode, the photometric parameters of the camera will be automatically transmitted to the flash at the same time. At this time, the flash will emit a flash with appropriate brightness. In most cases, the exposure of the subject is matched with the background brightness, and the film can be released without the user's further consideration.

3. If you feel that the subject is too bright or too dark after shooting, press the camera's exposure compensation button at this time to make exposure compensation.

in addition, pay great attention to the settings of the camera and flash. The general setting suggestions are as follows:

1. In camera setting, it is necessary to set the flash synchronization speed in aperture priority mode to automatic.

2. Press the high-speed synchronization entity button of the flash at the same time until the highlighted H and flash symbol appear in the upper left corner of the screen.

as long as the above two conditions are met simultaneously. The camera can realize high-speed synchronization in AV file. Correct flash photography can be achieved in most cases.
