Use off-camera flash.
During a wedding, our speedlites are never on-camera, even during the reception. Flash rarely flatters a person’s face when it is straight on, and the image looses its dimensionality.
Using flash to light our subjects from the side, we are able to create both light and shadow on our subjects, flattering their features and bringing a greater range of highlights and shadows to the image. It also helps us bring out details in the background to create a more dramatic landscape.
Yeah that was a good technique avoiding those unwanted light on flash to make it natural scene
